Server Quality Checklist
Latest release: v2.2.3
- Disambiguation5/5
Each tool serves a clearly distinct purpose: interactive_feedback collects user feedback via a web UI, and get_system_info retrieves system environment details. There is no overlap or ambiguity between them.
Naming Consistency2/5The tool names do not follow a consistent pattern. 'interactive_feedback' is an adjective-noun phrase while 'get_system_info' follows a verb_noun convention, mixing styles and making the set feel inconsistent.
Tool Count3/5With only 2 tools, the server is on the thin side. The system info tool seems unrelated to the core feedback domain, so the count feels slightly inflated for the apparent purpose.
Completeness4/5The interactive_feedback tool provides a complete feedback loop, including handling skips, termination, and rich summaries, so there are no obvious gaps in the primary purpose. The system info tool is an extra that doesn't address any feedback-related gap.
Average 4.4/5 across 2 of 2 tools scored. Lowest: 3.8/5.

Add a LICENSE file by following GitHub's guide. Once GitHub recognizes the license, the system will automatically detect it within a few hours.
If the license does not appear after some time, you can manually trigger a new scan using the MCP server admin interface.
MCP servers without a LICENSE cannot be installed.
This repository includes a README.md file.
No tool usage detected in the last 30 days. Usage tracking helps demonstrate server value.
Tip: use the "Try in Browser" feature on the server page to seed initial usage.
Add a glama.json file to provide metadata about your server.
If you are the author, simply .
If the server belongs to an organization, first add
glama.jsonto 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
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It discloses the return type (string in JSON format), and the verb 'get' implies a read-only operation. However, it does not explicitly state that it is non-destructive or describe any potential side effects, which would be helpful for a tool with no annotations.
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 extremely concise, consisting of two short lines. It front-loads the core purpose and immediately provides return format information, with no wasted words.
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?
For a simple, parameterless tool with an output schema (indicated by the Returns section), the description is sufficiently complete. It tells the agent what the tool returns and in what format, which is all that is needed for this straightforward operation.
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 tool has zero parameters, so the baseline is 4. The description does not need to explain parameters, and indeed mentions none, which is appropriate for a parameterless tool.
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 '获取系统环境信息' (Get system environment information), which is a specific verb and resource. It unambiguously distinguishes from the sibling tool 'interactive_feedback', which is about user feedback rather than system data.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does 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 only states what the tool does without mentioning any exclusions, prerequisites, or comparisons to sibling tools.
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 are provided, so the description carries the full burden. It transparently discloses runtime validation (empty/placeholder rejection), the meaning of an empty result (user skipped → re-call), timeout behavior, and explicit termination terms. This goes well beyond basic behavior.
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 well-structured with clear sections (Strict prohibitions, summary rules, title rules, Args, Returns). It is front-loaded with the purpose and every section contains actionable rules without fluff, making the length justified.
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 no annotations and no output schema, the description fully compensates by covering purpose, usage, parameter semantics, return behavior (including image uploads), and error handling. It leaves little ambiguity for an agent selecting and invoking the tool.
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?
Schema description coverage is 100%, so baseline is 3. The description adds value beyond the schema by providing writing rules (e.g., Markdown requirements, title ≤30 chars with examples), reinforcing that summary is effectively required despite its schema default, and setting a minimum timeout (≥600).
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 'Open a Web UI to collect interactive feedback from the user,' which is a specific verb plus resource. It also positions itself as the PRIMARY communication channel, distinguishing it from the sibling get_system_info and explicitly contrasting it with Cursor's AskQuestion.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides explicit when-to-use and when-not-to-use guidance: 'DO NOT invoke Cursor's built-in AskQuestion' and 'DO NOT end the turn with a plain-text reply.' It also details the re-call policy on user skip and notes that full scenarios live in external rules, but the operational guidelines here are comprehensive.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
