Server Quality Checklist

67%
Profile completionA complete profile improves this server's visibility in search results.
  • Latest release: v1.0.0

  • Disambiguation5/5

    The two tools have clearly distinct purposes: one retrieves message history, the other sends a message and waits for a reply. No overlap or ambiguity.

    Naming Consistency5/5

    Both tools follow a consistent verb_noun pattern in snake_case (get_history, send_message), making them predictable and easy to understand.

    Tool Count2/5

    With only 2 tools for a Telegram bot server, the surface is too thin. Typical Telegram interactions require more operations (e.g., listing bots, deleting messages), making this feel incomplete.

    Completeness2/5

    Obvious gaps exist: no tool to list available bots, delete messages, get updates, or handle multiple bots. The set covers only basic send and retrieve operations.

  • Average 4/5 across 2 of 2 tools scored.

    See the Tool Scores section below for per-tool breakdowns.

  • If you are the author, simply .

    If the server belongs to an organization, first add glama.json to the root of your repository:

    {
      "$schema": "https://glama.ai/mcp/schemas/server.json",
      "maintainers": [
        "your-github-username"
      ]
    }

    Then . Browse examples.

  • Add related servers to improve discoverability.

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 bears full responsibility for behavioral disclosure. The description only states 'Get message history' but does not mention read-only nature, authentication requirements, rate limits, or behavior with large limits. Given the lack of annotations, this is a significant gap.

    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—four short lines—and well-structured with clear 'Args:' listing. Every sentence adds value with no wasted words. It is appropriately sized for a simple tool with two parameters.

    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 low complexity (2 parameters), the presence of an output schema (so return values need not be explained), and the minimal sibling context, the description is fairly complete. It could optionally mention that it retrieves messages from a bot conversation, but the current description is sufficient for basic use.

    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 description adds meaning beyond the input schema by providing examples for the 'bot' parameter ('e.g. '@BotFather' or 'BotFather'') and clarifying the default for 'limit' (20). With 0% schema description coverage, the description compensates well, though it could elaborate on the format or constraints of 'limit'.

    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 verb and resource: 'Get message history with a Telegram bot.' This distinguishes it from the sibling tool 'send_message', which sends messages. The purpose is specific and 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 implicitly indicates when to use this tool (retrieve history) versus the sibling 'send_message' (send messages). However, it does not explicitly state when not to use it or provide alternatives beyond the sibling context. This is adequate for a simple list retrieval tool.

    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 mentions waiting for a reply and the timeout parameter, but lacks details on error handling, authentication needs, or destructive behavior. Transparency is adequate but not comprehensive.

    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, front-loaded with the purpose, and uses a structured docstring format (Args section). Every sentence adds value, with no wasted words.

    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 3 parameters, no schema descriptions, and an existing output schema (not shown), the description covers the main inputs adequately. It does not describe the return value, but that is mitigated by the output schema. Missing details on prerequisites or edge cases are minor gaps.

    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 input schema has 0% description coverage, so the description adds critical meaning: bot as Bot username, message as text, timeout as seconds. This compensates well, though bot format (with/without @) could be clearer.

    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 'Send a message to a Telegram bot and wait for its reply,' specifying the verb (send), resource (message to a Telegram bot), and behavior (wait for reply). It is distinct from the sibling tool get_history.

    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?

    The description implies usage (send and wait for reply) but does not provide explicit guidance on when to use this tool versus alternatives, nor does it state exclusions or prerequisites. The context of a single sibling reduces the need, but no explicit guidelines are given.

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