  • Latest release: v1.0.0

  • Disambiguation5/5

    The two tools have clearly distinct purposes: one converts time between timezones, and the other retrieves the current time in a specific timezone. There is no overlap or ambiguity in their functions, making it easy for an agent to select the correct tool based on the task.

    Naming Consistency5/5

    Both tool names follow a consistent verb_noun pattern (convert_time and get_current_time), using snake_case throughout. The naming is predictable and readable, with no deviations or mixed conventions.

    Tool Count2/5

    With only 2 tools, the server feels thin for a time-related domain. While the tools cover basic time conversion and current time retrieval, there are likely missing operations such as time calculations, scheduling, or handling date formats, which could limit functionality for agents.

    Completeness2/5

    The tool surface is severely incomplete for a time server. It lacks essential operations like adding/subtracting time, parsing dates, formatting times, or handling recurring events. Agents will encounter dead ends when trying to perform common time-related tasks beyond the two provided tools.

  • Average 3/5 across 2 of 2 tools scored.

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?

    With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions getting current time but doesn't specify whether this requires authentication, has rate limits, returns errors for invalid timezones, or provides output format details. This leaves significant gaps for a tool that interacts with time data.

    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 directly states the tool's function without unnecessary words. It's appropriately sized for a simple tool with one parameter and gets straight to the point.

    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 the output looks like (e.g., timestamp format, timezone handling), error conditions, or behavioral constraints. The simplicity of the tool doesn't compensate for these missing contextual elements.

    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?

    The schema description coverage is 100%, with the parameter 'timezone' fully documented in the schema (including IANA format and default behavior). The description adds no additional parameter information beyond what's in the schema, so it meets 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 'Get' and resource 'current time' with the scope 'in a specific timezone', making the purpose understandable. However, it doesn't explicitly differentiate from the sibling tool 'convert_time', which likely handles time conversion rather than current time retrieval.

    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 the sibling 'convert_time' or any alternatives. It lacks context about when this tool is appropriate versus other time-related operations, offering only a basic functional statement.

    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 the tool's function but doesn't disclose behavioral traits like error handling, format validation, or what happens with invalid inputs. For a tool with no annotations, this leaves significant gaps in understanding its operation.

    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 front-loaded and appropriately sized for the tool's complexity, making it easy to understand quickly without unnecessary elaboration.

    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 moderate complexity (3 parameters, no output schema, no annotations), the description is minimally adequate. It covers the basic purpose but lacks details on behavior, error cases, or output format, which are important for a conversion tool without structured output documentation.

    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 all parameters. The description adds no additional meaning beyond what's in the schema, such as examples or edge cases. Baseline 3 is appropriate as the schema handles parameter documentation effectively.

    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 'Convert time between timezones' clearly states the verb (convert) and resource (time), specifying the operation's scope. It distinguishes from the sibling 'get_current_time' by focusing on conversion rather than retrieval, though it doesn't explicitly mention this distinction.

    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 is provided on when to use this tool versus alternatives. The description doesn't mention prerequisites, constraints, or compare it with 'get_current_time'. Usage is implied by the purpose but lacks explicit context or exclusions.

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