This server has critical definition quality gaps across all four tools. While input schemas are present in the code, they are minimal and incomplete. Tool descriptions lack essential context about prerequisites, state mutations, and when to use each tool. Parameter descriptions are sparse or missing. No output schemas are documented. The server registers tools through a custom MCPTool base class, but critical information for LLM reasoning is absent. Only the polymarket and grok_research tools have non-trivial descriptions; youtube_uploader and github_tool descriptions lack depth. No error handling guidance is evident. Security concerns are acute: youtube_uploader exposes OAuth token files and client secrets via environment variables without proper vault integration, and no mention of permission gates or audit logging.
Tools (4)
github_toolwriteauth47/100
Interact with GitHub issues and PRs (list, create, comment)
grok_researchread onlyauth50/100
Perform aggressive web research and information synthesis. Returns a synthesized answer with source citations. Use for time-sensitive, technical, or factual verification tasks.
youtube_uploader exposes credentials as files and environment variables without vault integration. Tokens and client secrets risk leaking into logs and LLM traces.
github_tool parameter 'action' is an enum but lacks dependency documentation. Parameters like 'title' and 'body' are conditional on action type but no description clarifies which params apply to which action.
youtube_uploader description does not state that this tool modifies state (uploads media). LLMs need to know this is not idempotent and has irreversible consequences.
youtube_uploader
Recommendations
Add documented return schemas for all four tools. Example for polymarket: {"markets": [{"id": "string", "title": "string", "volume": "number", "category": "string", "slug": "string"}], "total_count": "number", "returned": "number"}
Rewrite youtube_uploader description to explicitly state: 'Uploads a video file to YouTube. This modifies state and is NOT idempotent, repeated calls with the same file will create duplicate uploads. Requires valid YouTube OAuth credentials and a file path to an MP4 or MOV video under 128 GB.'
Document github_tool parameter dependencies clearly: 'action: enum [list_issues | create_issue | comment_issue | get_issue]. When action=list_issues, pass repo and optionally state, title, issue_number are ignored. When action=create_issue, pass repo, title, body; issue_number is ignored. When action=comment_issue, pass repo, issue_number, body; title is ignored. When action=get_issue, pass repo, issue_number; title and body are ignored.'
Add pagination support to polymarket with limit (1-50) and offset or cursor. Document max returned results and how to fetch the next page.
Refactor youtube_uploader to use server-side OAuth token storage. Remove CLIENT_SECRETS_FILE and TOKEN_FILE path exposure. Store credentials in a secure vault and pass a reference identifier, not the actual secret files.
Add explicit error recovery guidance to polymarket: 'If API returns HTTP 429 (rate limit), wait 60 seconds and retry. If returns 500, this tool cannot proceed, inform the user that Polymarket API is temporarily unavailable.'
polymarket and github_tool descriptions lack guidance on when to use them vs. similar tools. 'Fetch Trending Markets' does not explain why this tool over search_polymarket or other market sources.
No error handling or recovery guidance visible in tool code. LLMs receive raw exceptions rather than actionable error messages with suggested next steps.
youtube_uploader 'video_path' parameter lacks validation guidance. No description states required format, supported codecs, size limits, or location constraints (local vs. remote).
grok_research 'model' parameter has a default but description does not explain what happens if omitted or what other valid models exist. LLM cannot reason about trade-offs.
grok_research
Expand grok_research description: 'Performs web research using Grok-2. Returns synthesized answer with citations. Use for: time-sensitive news, technical verification, factual claims. Model defaults to grok-2-latest; other models: grok-2-vision for image search, grok-2-research for in-depth analysis. Response includes sources field with [title, url, snippet].'
Add permission/scope declarations to all tools. Example: youtube_uploader requires [write:youtube_upload], github_tool requires [read:github_issues, write:github_issues] depending on action.
Add audit logging: log tool invocations with caller ID, parameters (excluding secrets), timestamp, and outcome to stderr or a secure audit trail for compliance.
Split github_tool into separate tools: list_github_issues, create_github_issue, comment_github_issue, get_github_issue. Each tool has one clear responsibility and simpler parameter schemas.
