Server Quality Checklist

Profile completionA complete profile improves this server's visibility in search results.

Latest release: v1.1.1
Disambiguation5/5
Each tool has a clearly distinct purpose: ACP session management, credit/cost operations, document generation (single/batch), template management (create, get, list, search), URL refresh, and feedback. There is no ambiguity or overlap between tools.
Naming Consistency5/5
All tools use a consistent verb_noun pattern in snake_case. ACP-related tools are prefixed with 'acp_' for clarity. The naming scheme is predictable and makes it easy to infer each tool's function.
Tool Count5/5
With 15 tools, the server is well-scoped. It covers all core functionalities (template management, document generation, ACP checkout, credits, batch operations, and feedback) without being overwhelming or trivial.
Completeness4/5
The tool surface covers the main lifecycle: template creation (via DOCX), listing/searching, generation (single/batch), ACP session handling, credit checks, cost estimation, and URL refresh. Minor gaps exist (e.g., no template deletion or update), but agents can work around them.
Average 4.2/5 across 15 of 15 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

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Discloses return of ZIP URL and credit costs, but lacks deeper behavioral details like error handling, prerequisites, or side effects. No annotations to fall back on.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences with front-loaded purpose and result. No extraneous information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a batch generation tool without output schema, it mentions return type and costs but could include more on URL lifecycle or error handling.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so description's credit cost info adds marginal value beyond the schema's enum description. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states it generates documents for multiple records in one call, returns a ZIP download URL, and distinguishes from sibling tools like generate_document (single record).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Implies usage for batch generation but does not explicitly state when not to use or provide alternatives. No exclusions mentioned.
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?
Description implies read-only listing, but no explicit statement about side effects or permissions. With no annotations, the description adequately conveys the operation but lacks depth.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, no fluff, front-loaded with action and result.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Complete for a simple list tool with no parameters; explains what it does and returns. Could mention that it returns templates for the current context, but not necessary.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
No parameters exist; baseline for 0 params is 4. Schema coverage is 100% trivially, and description adds nothing extra, which is acceptable.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Clear verb 'List', resource 'available document templates', and specific return fields (names, IDs, file types, placeholder variables). Distinguishes from siblings like acp_list_public_templates by implying scope is all templates.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs search_templates or acp_list_public_templates. No context on prerequisites or limitations.
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?
With no annotations, the description bears the burden for behavioral disclosure. It states the tool returns current credit balance and is an estimation, implying no side effects. However, it does not explicitly confirm idempotency or safety, leaving some ambiguity.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise, using only three short sentences to convey purpose, usage guidance, and return information. Every sentence adds value with no redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (2 params, no output schema), the description covers purpose and usage well. It does not detail the return value structure, but for an estimation tool this may be acceptable.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with detailed parameter descriptions, so the description adds little beyond reinforcing that outputFormat affects cost. Baseline 3 is appropriate as the description does not introduce new parameter insights.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool estimates credit cost before document generation, distinguishing it from sibling tools that actually generate documents or check credits. It specifies the resource (credit cost) and action (estimate), making the purpose unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly advises calling this tool before large batches for user confirmation, providing a clear use case. It lacks explicit when-not-to-use guidance but is still strong.
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 the description must cover behavioral traits. It explains the tool returns details including variable schema, which implies a read operation. However, it does not disclose error behavior, required permissions, or specific response structure, leaving some gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise with two sentences, front-loading the action 'Get a template's details' and immediately providing the use case. Every sentence adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple (1 required param, no output schema). The description covers the main purpose and use case. It could optionally mention return format or error handling, but this is sufficient for the tool's complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%: the parameter templateId is described as 'Template UUID'. The description adds no additional parameter-level meaning beyond the schema, so baseline score of 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves a template's details including variable schema, and explicitly mentions its use case (understanding expected data fields before generating documents). It distinguishes itself from sibling tools like list_templates and search_templates by focusing on a single template's details.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides a clear usage context: use this before generating documents to understand expected data fields. It does not specify when not to use it or mention alternatives, but the guidance is sufficient for the intended use.
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 must carry the full burden. It discloses a key behavioral trait: 'Does not consume credits.' However, it does not mention other traits like idempotency, required permissions, or error conditions (e.g., document not found). The disclosure is helpful but incomplete.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences long, front-loaded with the main purpose, and includes a crucial secondary detail (credit usage) in the second sentence. Every word earns its place with no unnecessary information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity, the description covers the essential purpose and usage. However, it lacks details about return format (a signed URL) and possible errors, but these are not critical for a basic URL refresh tool. With no output schema, the description could do slightly more, but it is still adequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the baseline is 3. The description adds no additional meaning beyond the schema for either parameter. It does not elaborate on 'documentId' or 'expiresIn' beyond what the schema already provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's function: 'Get a fresh signed download URL for an existing document.' It explicitly distinguishes from sibling tools like 'generate_document' by noting that it does not create a new document, and the credit-saving behavior further differentiates it.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit context for when to use the tool: 'Useful when a previously generated document's URL has expired.' While it does not explicitly state when not to use it or suggest alternatives, the usage context is clear and sufficient for an agent.
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 are provided, so the description carries full burden. It discloses the fetch process, placeholder extraction, and return value. However, it omits details like authentication requirements for the URL, file size limits, or error handling.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5

Two sentences, front-loaded with the purpose, no wasted words. Efficient and clear.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 5 parameters, no output schema, and no annotations, the description covers the main process and return value. It lacks details on error conditions or constraints (e.g., public URL requirement).
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline is 3. The description does not add significant new meaning to parameters beyond what the schema provides, e.g., docxUrl is already described as a URL to a DOCX file.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description specifies the action (create template), resource (DOCX URL), and outcome (templateId, ready for generate_document). It clearly distinguishes from sibling tools like generate_document or list_templates.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies when to use (when you have a DOCX URL to create a template) but does not explicitly exclude alternatives or state when not to use. It points to generate_document as the consumer, which is helpful.
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 are provided, so the description carries the full burden. It discloses the credit cost and output format options, and that a signed download URL is returned. It does not mention idempotency, expiration, or failure modes, but the provided information is sufficient for basic understanding.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states it checks status of async batch generation job, explicitly mentions polling until 'completed', and lists return fields (progress, document count, download URLs). Distinguishes from generate_batch which starts the job.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Description tells agent to poll until completed, implying usage after generate_batch. No explicit when-not or alternatives, but siblings make the intended use 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 are provided, so the description fully bears the burden of behavioral disclosure. It explains the rationale for including the email (support follow-up, agents have no inbox) but does not mention other traits such as whether the action is destructive, rate limits, or expected response. For a simple submission tool, the coverage is adequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?

The description mentions 'No API key required' which is a usage condition, and indicates the returned data is needed for creating an ACP session. However, it doesn't explicitly exclude other use cases or compare to alternatives like list_templates.
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, but description discloses read-only behavior (shows credits) with no hidden traits. Does not contradict any annotations (none provided).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, no wasted words, front-loaded with purpose and detail. Excellent conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a no-parameter tool without output schema, description fully explains input (none) and output (credit breakdown). Complete and self-contained.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
No parameters; schema coverage 100% automatically. Description adds full meaning beyond empty schema, justifying baseline of 4.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states verb 'check' and resource 'credits' for the organization, breaking down into subscription credits, purchased packs, and total. Distinguishes from siblings as no other credit-related tool exists.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Implicitly clear when to use (need to check credits), but lacks explicit when-not or alternatives. Adequate given simplicity.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It discloses polling duration (5-30s), return values (documents, zip, credits, signup_cta), URL expiry (24h), and the required action of presenting signup_cta. This is comprehensive behavioral transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Single, information-dense paragraph front-loaded with purpose, then polling guidance, then return details, then key instruction. Every sentence adds value with no redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema, description fully explains return data: documents, signed_urls, expiry, zip, credits breakdown, signup_cta. Covers essential behavioral context (polling, expiry, user action needed) for correct agent invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has 100% description coverage on both parameters. Description adds cross-reference: 'Same bearer token used in acp_create_session' and 'session_id from acp_create_session,' clarifying tool interdependence beyond schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states the tool's function: 'Get the status of an ACP checkout session.' It differentiates from sibling tools like acp_create_session (which creates) and acp_pay_session (which pays) by focusing on status retrieval and polling.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides explicit usage context: 'Poll after payment until status is completed' with typical timing. Also instructs to present signup_cta URL after completion. Does not explicitly state when not to use, but the polling guidance implies alternatives like waiting for completion.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
