The server defines 6 read-only tools for repository search and file listing. Tool naming follows verb-noun conventions (list_repos, search, read_file, grep), which is good. However, descriptions vary in quality and completeness. Most critically, the source code provided does not include the actual MCP tool registration code, only package.json snippets and partial file references. This means tool definitions are partially inferred from the input descriptions provided in the evaluation data rather than directly verified in source. Schemas are documented in the input data but not fully visible in the source files shown. Parameters mostly have types and descriptions, but several lack important details like constraints, ranges, or validation rules. Error handling and recovery guidance are not evident in the provided code samples.

• Provide full source code from packages/mcp-server/src/main.ts showing actual tool.resource() and tool.tool() registrations with complete schema definitions, so definitions can be directly verified rather than inferred.
• Document output schemas for all tools. Specify: return type (object/array), field names, field types, pagination structure if applicable. Example for search: 'Returns array of {repo_id: string, path: string, matches: number, snippet: string}'.
• Add explicit min/max bounds to numeric parameters. For 'limit' params: document '1-100', for 'contextBefore/After': document '0-50' to prevent absurd values.
• Add error handling block to tool descriptions: 'If file not found, returns error 'FileNotFoundError: path does not exist in repo'. Try list_files() first to verify the path.'
• Clarify 'search' mode selection in description: 'Use keyword for exact text matches (fastest), semantic for meaning-based results (slower), hybrid for both. Default hybrid balances speed and relevance.'
• Rename 'offset' to 'start_line' in read_file for clarity. Document: 'Line numbers are 1-based: start_line=1 reads from the first line.'
• For 'grep' tool, document output format: return matches as array of {file: string, line_number: number, line_content: string, ...context} to enable LLM to reference specific matches.
• Add dependency hints to tool descriptions. E.g., 'Use list_files() or glob_files() first to discover available paths before calling read_file().'
• Consider adding batch variants or result limiting. 'grep' with limit=100 could return 100 total lines across many files, clarify if this is per-file or total.
