Server Quality Checklist

67%
Profile completionA complete profile improves this server's visibility in search results.
  • Latest release: v0.1.1

  • Disambiguation5/5

    Each tool has a clearly distinct purpose targeting specific resources and actions: account info, template operations (get/list), and request operations (create/get/list/cancel). No overlap exists between tools, making it easy for an agent to select the correct one.

    Naming Consistency5/5

    All tools follow a consistent verb_noun naming pattern (e.g., get_account, list_templates, create_request). The verbs are appropriate and predictable, with no deviations in style or convention.

    Tool Count5/5

    With 7 tools, this server is well-scoped for its PDF and e-signing domain. Each tool serves a clear purpose, covering account management, template handling, and request lifecycle without being overly sparse or bloated.

    Completeness5/5

    The toolset provides complete CRUD/lifecycle coverage for the domain: account info (get), templates (list/get), and requests (create/get/list/cancel). It supports fill-only and e-signing workflows with no obvious gaps, ensuring agents can handle end-to-end processes.

How to sync the server with GitHub?

Servers are automatically synced at least once per day, but you can also sync manually at any time to instantly update the server profile.

To manually sync the server, click the "Sync Server" button in the MCP server admin interface.

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 carries the full burden. It states the tool cancels a pending signing request, implying a mutation operation, but lacks details on permissions needed, whether cancellation is reversible, side effects, or error conditions. This is inadequate for a mutation tool with zero annotation coverage.

    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 a single, efficient sentence with zero waste. It's appropriately sized and front-loaded, clearly stating the tool's purpose without unnecessary elaboration.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the complexity (a mutation tool with no annotations and no output schema), the description is incomplete. It doesn't cover behavioral aspects like success/error responses, prerequisites, or integration with sibling tools, leaving significant gaps for an AI agent to understand proper usage.

    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%, with the 'id' parameter fully documented in the schema. The description adds no additional meaning beyond what the schema provides, such as clarifying the 'pending' status requirement or format examples. Baseline 3 is appropriate when the schema does the heavy lifting.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Cancel') and the target resource ('a pending signing request'), which provides a specific verb+resource combination. However, it doesn't explicitly differentiate from sibling tools like 'list_requests' or 'get_request' in terms of when to use cancellation versus other operations.

    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?

    The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., the request must be pending), exclusions (e.g., cannot cancel completed requests), or refer to sibling tools like 'create_request' or 'get_request' for context.

    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 provided, the description carries full burden but only states it lists with optional filters. It doesn't disclose behavioral traits like whether this is a read-only operation (implied but not stated), pagination behavior beyond what's in schema, rate limits, authentication requirements, or what happens when no filters are applied. Significant gaps remain for a tool with 3 parameters.

    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 a single, efficient sentence that gets straight to the point with zero wasted words. It's appropriately sized for a list operation and front-loads the core functionality. Every word earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a list operation with 3 parameters and no annotations or output schema, the description is incomplete. It doesn't explain what 'signing requests' are in this context, what the return format looks like, or provide behavioral context needed for proper use. The agent would need to guess about important aspects of the tool's behavior.

    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 schema already fully documents all 3 parameters with descriptions, defaults, and enum values. The description adds no additional parameter semantics beyond mentioning 'optional filters' which is already implied by the schema. Baseline 3 is appropriate when schema does all the work.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb ('list') and resource ('signing requests'), making the purpose immediately understandable. It distinguishes from siblings like 'get_request' (singular) and 'create_request' (write operation). However, it doesn't specify scope (e.g., 'all' or 'accessible') which would make it a perfect 5.

    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?

    The description provides no guidance on when to use this tool versus alternatives. It doesn't mention when to use 'list_requests' versus 'get_request' (for single request details) or 'list_templates' (for templates instead of requests). No prerequisites, exclusions, or context for filtering are provided.

    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 provided, the description carries full burden for behavioral disclosure. While 'List all PDF templates' implies a read operation, it doesn't mention pagination behavior (implied by parameters), rate limits, authentication requirements, or what 'available for filling and signing' means operationally. The description is too sparse for a tool with parameters.

    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 a single, efficient sentence that gets straight to the point with zero wasted words. It's appropriately sized for a simple list operation and front-loads the core functionality.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with no annotations and no output schema, the description is insufficient. It doesn't explain what information is returned about each template, how results are structured, or provide context about the 'filling and signing' capability mentioned. The agent would need to guess about the response format and practical usage.

    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 schema fully documents both parameters (page and page_size). The description doesn't add any parameter-specific information beyond what's already in the schema, meeting the baseline for high schema coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb ('List') and resource ('all PDF templates available for filling and signing'), making the purpose immediately understandable. However, it doesn't differentiate from sibling tools like 'get_template' or 'list_requests', which would require more specific scope definition.

    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?

    The description provides no guidance on when to use this tool versus alternatives like 'get_template' (for individual templates) or 'list_requests' (for requests rather than templates). There's no mention of prerequisites, typical use cases, or exclusion criteria.

    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, so the description carries the full burden of behavioral disclosure. It states this is a read operation ('Get'), implying it's non-destructive, but doesn't cover aspects like authentication requirements, rate limits, error conditions, or what the return format looks like (e.g., JSON structure). This leaves significant gaps for a tool with no annotation coverage.

    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 a single, efficient sentence that front-loads the core purpose without unnecessary words. Every part ('Get request details including signer status and signing links') contributes directly to understanding the tool's function.

    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?

    Given the tool's low complexity (1 parameter, no nested objects) and high schema coverage (100%), the description is minimally adequate. However, with no annotations and no output schema, it should provide more behavioral context (e.g., return format or error handling) to be fully complete, keeping it at a baseline level.

    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%, with the single parameter 'id' documented as a UUID-formatted 'Request ID'. The description doesn't add any meaning beyond this (e.g., explaining where to find the ID or format nuances), so it meets the baseline of 3 where the schema does the heavy lifting.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's purpose with a specific verb ('Get') and resource ('request details'), including what information is retrieved ('signer status and signing links'). However, it doesn't explicitly differentiate from sibling tools like 'list_requests' or 'get_template', which would require a 5.

    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?

    The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing a request ID), exclusions, or comparisons to siblings like 'list_requests' for bulk retrieval or 'get_template' for template details.

    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 provided, the description carries the full burden of behavioral disclosure. It indicates a read operation ('Get') but doesn't specify whether it requires authentication, has rate limits, returns errors for invalid IDs, or what format the details are in. For a tool with zero annotation coverage, this leaves significant behavioral 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 a single, efficient sentence that front-loads the purpose without unnecessary words. Every part ('Get template details including form field names and signer labels') contributes directly to understanding the tool's function, making it highly concise and well-structured.

    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?

    Given the tool's low complexity (1 parameter, no output schema, no annotations), the description is minimally adequate. It covers the basic purpose and data returned but lacks behavioral context (e.g., error handling, auth needs) and output details. Without annotations or output schema, more completeness would be beneficial, but it meets the minimum for a simple read tool.

    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%, with the single parameter 'id' fully documented in the schema as a UUID Template ID. The description adds no parameter-specific information beyond what the schema provides, such as example IDs or context on where to obtain them. Baseline 3 is appropriate when the schema does the heavy lifting.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get') and resource ('template details'), specifying what information is retrieved ('form field names and signer labels'). It distinguishes from siblings like 'list_templates' (which likely lists templates without details) and 'get_request' (which retrieves request details). However, it doesn't explicitly contrast with all siblings, keeping it at 4 rather than 5.

    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?

    The description provides no guidance on when to use this tool versus alternatives like 'list_templates' or 'get_request'. It doesn't mention prerequisites (e.g., needing a template ID) or exclusions. Usage is implied by the name and description but not explicitly stated, resulting in minimal guidance.

    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, so the description carries full burden. It states this is a 'Get' operation which implies read-only behavior, but doesn't disclose any behavioral traits like authentication requirements, rate limits, error conditions, or what specific 'account info' fields are returned. For a tool with zero annotation coverage, this leaves significant gaps in understanding how it behaves.

    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 a single, efficient sentence that communicates the core purpose without any wasted words. It's appropriately sized for a simple retrieval tool and front-loads the essential information. Every word earns its place.

    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?

    Given the tool's simplicity (0 parameters, no output schema, no annotations), the description is minimally adequate. It states what information is retrieved but doesn't provide enough context about the return format or behavioral characteristics. For a tool that presumably returns account data, more detail about what 'plan and usage' entails would be helpful, especially without an output schema.

    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?

    The tool has 0 parameters with 100% schema description coverage, so the baseline is 4. The description doesn't need to compensate for any parameter documentation gaps. It appropriately focuses on what the tool does rather than parameter details when none exist.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb ('Get') and resource ('account info'), specifying what information is retrieved ('including plan and usage'). It distinguishes this tool from siblings like 'get_request' or 'get_template' by focusing on account-level data rather than request/template details. However, it doesn't explicitly differentiate from all siblings in the description text itself.

    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?

    The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites, appropriate contexts, or exclusions. With siblings like 'get_request' and 'get_template' that also retrieve information, the agent receives no help in choosing between them based on the description alone.

    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 provided, the description carries the full burden of behavioral disclosure. It clearly indicates this is a write operation (fill/create) with optional side effects (e-signing), but doesn't mention permissions required, rate limits, whether the operation is idempotent, or what happens on failure. The description adds some context about the signer flow but lacks comprehensive behavioral details needed for a mutation tool.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is perfectly concise with just two sentences that each earn their place. The first sentence states the core functionality, and the second provides crucial usage guidance about the signers parameter. No wasted words, and the most important information is front-loaded.

    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 complex mutation tool with 6 parameters, nested objects, and no output schema, the description is adequate but incomplete. It covers the basic purpose and key parameter guidance but lacks information about return values, error conditions, authentication requirements, and how this tool relates to siblings like get_request or cancel_request. The absence of annotations increases the need for more comprehensive description.

    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 schema already documents all 6 parameters thoroughly. The description adds minimal value beyond the schema by implying that 'signers' parameter controls the e-signing behavior, but doesn't provide additional semantic context about parameter interactions or usage patterns. Baseline 3 is appropriate when the schema does the heavy lifting.

    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 specific action ('Fill a PDF template') and resource ('PDF template'), and distinguishes this tool from siblings by mentioning the optional e-signing capability. It explicitly contrasts with fill-only usage, making the purpose unambiguous and differentiated from other tools in the server.

    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 clear guidance on when to use the tool ('Fill a PDF template and optionally send it for e-signing') and includes a specific exclusion rule ('Omit signers for fill-only'). However, it doesn't explicitly mention when NOT to use this tool versus alternatives like get_template or list_templates, nor does it reference sibling tools for related operations.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
