This MCP server exhibits critical quality gaps across naming, descriptions, and schema documentation. All 10 tools share a pervasive pattern of indirect/delegated documentation ('Use how_to_use() for details') rather than explicit, self-contained descriptions. No input parameter descriptions are visible in the provided source. Schemas are present in the assessment but lack evidence of full JSON Schema compliance with type definitions for all parameters. The server operates at STDIO only, which further limits production suitability. While tool names follow verb_noun convention (code_index_project, code_list_projects, etc.), the reliance on external how_to_use() references instead of inline documentation violates the principle that LLMs must infer tool purpose from the definition alone.

• Replace all how_to_use() delegation with inline, self-contained descriptions. Each description must answer: WHAT does the tool do? WHEN should the LLM call it instead of a similar tool? WHAT does it return? Target 50 - 200 characters per description (baseline: 194 chars avg for A+ tools).
• Add explicit descriptions to EVERY parameter. For code_index_project, document: 'project_path: Absolute path to the root directory of the project to index. Must exist and be readable. Example: /home/user/my-project' and 'languages: List of target programming languages to analyze. If omitted, all supported languages are indexed. Valid values: go, typescript, python, rust, java, c, cpp, etc.'
• Document output schemas for all tools. Show what fields code_index_project returns (e.g., job_id, status, project_id, estimated_duration, created_at) so LLMs know what to extract for downstream calls like code_index_status.
• Add a confirmation or dry-run parameter to code_delete_project. Accept an optional 'confirm_delete: boolean' parameter. If false or omitted, return 'Would delete project {project_id}. Call again with confirm_delete=true to proceed.' This prevents accidental deletions.
• Specify constraints on parameters. For 'project_path', document that it must be an absolute path or indicate if relative paths are resolved from a working directory. For 'languages', provide an enum: ['go', 'typescript', 'python', 'rust', 'java', 'c', 'cpp', ...] so LLMs know the valid set.
• Document expected errors and recovery paths. For code_index_project, add: 'May return: project_not_found (call code_list_projects() first), permission_denied (check directory ownership), invalid_path (verify the path exists), already_indexing (wait for current job to complete or call code_index_status with the job_id).'
