HasData MCP Server
OfficialServer Quality Checklist
Latest release: v1.0.1
- Disambiguation4/5
Most tools have distinct purposes across different domains (Amazon, Google Maps, etc.), but the large number of Google-related tools (e.g., multiple 'getMapReviews' variants and various SERP tools) can cause some confusion due to similar naming and overlapping functionality.
Naming Consistency3/5Tools generally follow a `source_category_action` snake_case pattern, but there are inconsistencies such as the odd `getImmersive_e29f691177` suffix, double underscores, and occasional mixing of depth levels (e.g., `hasdata_google_serp_ai_mode_getAiModeResponse`).
Tool Count3/535 tools is quite high for a single server, covering many different data sources. This broad scope may be overwhelming and suggests the server might benefit from splitting into domain-specific servers, but each tool individually seems purposeful.
Completeness3/5Coverage is broad across multiple domains, but depth varies. Some domains like Amazon and Google Maps have decent coverage, while others have gaps (e.g., no LinkedIn, Twitter, or full Google SERP organic results). The generic web scraper helps fill some gaps but not all.
Average 4/5 across 35 of 35 tools scored.

How is the quality score calculated?
The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).
Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.
Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).
Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.
Tool Scores
- Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description fully bears the responsibility. It describes the tool as a paginated fetch and lists return fields, but omits how pagination works (e.g., nextPageToken usage), rate limits, or authentication. This leaves key behavioral details unclear.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single paragraph that front-loads the purpose and efficiently conveys key information. It could be better structured (e.g., bullet points for return fields), but it is clear and without excessive verbosity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the main purpose, parameters, and return data, which is sufficient for a simple read tool. However, it lacks explanation of pagination mechanics (how to use nextPageToken) and error conditions, leaving some gaps given no output schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% parameter description coverage, providing basic definitions. The description adds value by explaining sorting options (qualityScore, newestFirst, etc.) and the topic filter, but does not elaborate on parameters beyond what schema already states.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool fetches Google Maps reviews for a place, using dataId or placeId, with sorting, filtering, and language options. It distinguishes itself from sibling tools like 'getMapPhotos' by focusing on reviews, but does not explicitly differentiate from the contributor reviews tool.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description lists specific use cases (reputation management, sentiment mining, etc.), providing clear context for when to use the tool. However, it does not mention when not to use it or compare with alternative tools (e.g., contributor reviews).
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, and the description only mentions 'Paginated fetch' without detailing rate limits, authentication needs, or error behavior. It does not disclose what happens on API limits or missing data, leaving gaps for an agent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences: a clear introductory line and a concise second sentence that packs the features and use cases. No redundant text, but could be more structured with bullet points for readability.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description lists return fields (title, body, rating, etc.) which partially compensates for missing output schema. However, given the tool's complexity (10 parameters, pagination), it lacks details on pagination limits, default page size, or error scenarios.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with parameter descriptions, so the baseline is 3. The description enumerates filter options (star rating, reviewer type, etc.) but does not add meaning beyond the schema. For instance, 'positive' and 'critical' stars are not explained.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Get Amazon Product Reviews' and specifies the action (paginated fetch) and resource (Amazon ASIN). It distinguishes itself from sibling tools by focusing specifically on product reviews.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description lists several use cases (voice-of-customer analysis, sentiment extraction, etc.) but does not explicitly state when NOT to use this tool or compare it to siblings like getProductDetails or search. It gives context but lacks exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, and the description does not disclose behavioral traits such as read-only nature, rate limits, or authentication requirements. The description focuses on functionality rather than behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single concise paragraph that efficiently conveys purpose, returned fields, and use cases. No redundant information, though bullet points could improve readability.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with 5 parameters and no output schema, the description covers the main purpose and return fields but lacks information on output structure, pagination limits, or potential side effects. Adequate but not fully complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the schema already describes all parameters. The description adds minimal context by mentioning 'language/country targeting' and 'nextPageToken pagination', but does not enrich parameter meaning beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool lists all Google Maps reviews for a specific contributor by contributorId, distinguishing it from sibling tools like getMapReviews for place reviews.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides specific use cases like reviewer reputation checks and fake review detection, making it easy to decide when to use this tool. No explicit exclusion of alternatives, but the context is clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description must disclose behavior. It mentions pagination and returned fields but lacks details on rate limits, authentication, error handling, or output structure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5Is the description appropriately sized, front-loaded, and free of redundancy?
Description is two paragraphs; first sentence repeats the title. Could be more front-loaded and concise. Adequate but not efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema, so description must detail return format. It lists fields but not structure or pagination behavior. Missing details on how to interpret results, pagination limits, or total pages.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so baseline is 3. Description reinforces that keyword is a zipcode but adds no new meaning beyond the schema descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it retrieves Redfin real estate listings by zipcode with pagination, lists specific fields returned, and distinguishes from sibling tools like the property details endpoint.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides explicit use cases (market research, lead generation, trend analysis) and mentions feeding URLs to the property endpoint. Does not explicitly say when not to use or list alternatives, but context is clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. The tool name 'Get' implies read-only, but the description does not confirm it is non-destructive, nor does it mention rate limits, authentication needs, or what happens on failure. This lack of explicit behavioral disclosure is a significant gap for a data-fetching tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is moderately concise, starting with the action and listing the return fields efficiently. It could be slightly tighter, but it is well-structured and avoids unnecessary words, earning a score of 4.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of the tool (returns a rich set of property details) and no output schema, the description comprehensively lists the data fields. However, it omits potential error conditions (e.g., invalid URL) and behavioral notes, which would enhance completeness. Overall, it covers the main use cases and outputs well.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 100% coverage (one parameter, 'url', with a clear description). The description adds context about using the URL to fetch the property page but does not provide additional semantic detail beyond the schema. Baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool fetches full Airbnb property details by listing URL, lists specific return fields (title, description, location, coordinates, price, fees, ratings, etc.), and distinguishes it from the sibling 'listing-search' endpoint by emphasizing deep-dive enrichment. This provides a specific verb+resource+scope.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly recommends use for travel-planning agents, deep-dive rate research, photo/amenity enrichment of listings from the listing-search endpoint, and compliance audits. It implies appropriate contexts but does not explicitly state when not to use it or mention alternatives beyond the listing-search endpoint.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It details the return components (conversational response, cited sources, subtopics, follow-ups, continuation token) and implies a read-only, AI-powered search, which is adequate behavioral disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single long paragraph that lists many use cases and examples, making it somewhat verbose and less concise. Not all sentences are essential; some redundancy exists between the use case list and examples.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
While the description covers the main purpose and return components, it lacks detailed parameter explanations (e.g., location, continuable) and does not compensate for the missing output schema. For a complex tool with 7 parameters and no output schema, more completeness is expected.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema covers 100% of parameters with descriptions, meeting the baseline for schema coverage. The description adds no extra parameter meaning beyond the schema, only mentioning the search term in examples. Thus, it does not improve parameter understanding beyond what the schema already provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool gets AI Mode SERP results from Google Search, listing the components returned. However, it does not differentiate from sibling tools like 'hasdata_google_serp_ai_overview_getAiOverviewResponse' or 'hasdata_google_serp_serp_getSearchResults', which may cause confusion.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides extensive use cases and example queries, giving clear context for when to use the tool. However, it does not specify when not to use it or mention alternative tools for similar tasks.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It describes the operation as a search returning list data, but does not mention read-only nature, authentication, or potential side effects. Adequate but not detailed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is front-loaded with the title and elaborates efficiently. A minor redundancy is the repeated title, but overall it is well-structured and concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description lists most returned fields but lacks details on pagination mechanics, date format expectations, and error handling. It covers use cases but could be more complete for a complex search tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the base score is 3. The description groups parameters and adds context but does not significantly enhance meaning beyond what the schema already provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with one parameter and no output schema or annotations, the description covers the core functionality and returned fields. However, it lacks details on error responses, data format, and any constraints. The description is minimally sufficient but not fully complete for an agent to anticipate all behaviors.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% description coverage for the single parameter 'handle', explaining it must be a username without '@'. The tool description adds minimal extra meaning beyond restating that the handle is used. Since the schema already fully documents the parameter, a baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves a public Instagram profile by handle, listing specific returned fields (full name, biography, etc.). The sibling tools are all for different platforms (Amazon, Google, etc.), making this tool distinct and uniquely identified for Instagram profile data.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly provides several use cases (enrich CRM, verify influencer reach, monitor competitors, build datasets), giving clear context for when to use it. However, it does not mention when NOT to use it or compare it to other tools, but given the lack of similar tools on the server, this is a minor omission.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Describes read-only data pulling and pagination, but lacks details on rate limits, authentication requirements for public stores, or error handling. Annotations are absent so description carries full burden.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description transparently covers the read-only nature, pagination, supported sort orders, delivery location scoping, and the structure of returned data. However, it omits details on rate limits, data freshness, or authentication requirements.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise, covering functionality, parameters, returns, and use cases in a single paragraph. It is front-loaded and each sentence adds value, though it could be structured with bullet points for clarity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description provides a detailed list of return fields and mentions related suggestions and facets. It is sufficient for understanding the tool’s role in product research and price comparison, though it lacks explicit mention of the response format.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% and the description adds little beyond listing parameters like 'domain' and 'sortBy'. It contextualizes their role in filtering and sorting but does not significantly extend the schema descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool performs a keyword search on Amazon domains with pagination, delivery scoping, and sort options. It enumerates return fields (ASIN, title, price, etc.) and lists concrete use cases like SERP monitoring and competitor discovery, distinguishing it from siblings such as product details or reviews.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Use cases are provided but no explicit guidance on when to use this tool versus alternatives. It does not mention when not to use it or contrast with sibling tools like product details or seller details, leaving the agent to infer based on return fields.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must convey behavioral traits. It explicitly states the tool 'Fetches the public storefront profile', confirming it is a read-only operation. It does not mention rate limits or authentication, but the read-only nature is clear.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences long and efficiently conveys purpose and return data. The first sentence serves as a clear verb+resource statement, and the second provides details and use cases. It is slightly dense but well-structured.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the absence of an output schema, the description compensates by listing the key data fields returned (business name, ratings, address, etc.). It also covers use cases sufficiently. No missing critical information for a seller details retrieval tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise, consisting of a header and two sentences that front-load the purpose and use cases. Every sentence adds value without redundancy, making it easy for an AI agent to quickly understand the tool's function and applicability.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one parameter, no output schema), the description is complete. It explains what the tool does, what parameters it takes, what data it returns (including a detailed list of fields), and provides relevant use cases. No additional information is needed for an agent to select and invoke this tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% coverage, with the sole parameter 'url' described as 'The URL of the job vacancy to retrieve details for.' The description adds context by specifying it is a 'viewjob URL' from Indeed. This provides enough meaning beyond the schema, though the schema already covers the basics adequately.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it 'Fetches a single Indeed job posting by its viewjob URL' and enumerates the specific fields returned (title, company, salary, etc.). This distinguishes it from the sibling tool 'hasdata_indeed_listing_getJobListings' which likely returns a list of postings, thereby providing clear differentiation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description lists explicit use cases: 'ATS/CRM enrichment, compensation benchmarking, resume-to-JD matching with LLMs, and structured archival of postings discovered via the Indeed Listing endpoint.' It implicitly suggests when to use this tool (for detailed single job data) versus the listing sibling. However, it does not explicitly state when not to use it or mention alternatives beyond the listing endpoint.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description carries full burden. It discloses that the tool returns businesses with specific fields and uses page-based pagination. However, it does not mention rate limits, authentication, or side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is three sentences, each packed with useful information. No fluff, clearly structured from summary to use case to output details.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with 5 parameters, 2 required, and no output schema, the description lists all return fields, explains pagination, and gives concrete usage scenarios. It is complete for the complexity level.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema covers all parameters with descriptions (100% coverage). The description adds value by explaining the sort options, domain targeting, and pagination pattern, reinforcing the schema's meaning.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description explicitly states 'Get YellowPages Search Results' and details the action: runs a business search by keyword and location with sort, domain, and page options. It distinguishes from sibling tools by mentioning the YellowPages Place endpoint for enrichment.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear use cases: B2B lead generation by niche and city, feeding URLs into Place endpoint, or building prospect lists. It implies when to use but does not explicitly state when not to use or compare to other search tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
