CodeAtlas MCP Server defines 4 tools with schemas and descriptions present, but significant gaps limit production readiness. Tool naming follows verb_noun convention (analyze, list_projects, get_project_structure, get_dependencies), which is positive. However, descriptions are functional but generic, they state WHAT the tool does but lack WHEN to use it or prerequisites. Parameter descriptions are present but sparse; many lack detail on constraints, formats, or valid ranges. Output schemas are not explicitly documented in the visible source code, the implementation returns text responses wrapped in { type: 'text', text: ... } but the expected structure for downstream tool chaining is not declared. Error handling is present (checking auth, path validation) but responses are text-only and lack recovery guidance. No tool annotations (readOnlyHint, destructiveHint, idempotentHint) are visible. The 'analyze' tool has a WRITE risk but the description does not state this has side effects or explain sync behavior clearly. No evidence of pagination for list_projects or get_project_structure despite these being discovery/list tools that should follow pattern:paginated-result. Overall: solid foundational definitions but missing the rigor for production-grade agent integration.

• Document output schemas for all tools. For list_projects, define: { projects: [ { name: string, path: string, lastAnalyzedAt: string (ISO 8601), stats?: { fileCount: number, classCount: number } } ], total: number }. For get_project_structure: { entities: [ { id: string, type: enum(module|class|function|variable), name: string, filePath: string, lineNumber: number } ], total: number, nextCursor?: string }.
• Add pagination to list_projects and get_project_structure. Include limit (default 20, max 100), offset or cursor parameters, and return total count. Document in descriptions: 'Returns max 20 projects by default; pass limit and offset for pagination.'
• Clarify analyze description: 'Analyzes a local project directory using AST parsing. Generates in-memory code graph and syncs metadata to CodeAtlas Cloud (requires network). Safe to retry but may be slow on large projects (>5000 files).'
• Add enum constraints for relationship types in get_dependencies: relationshipType enum: ['import', 'call', 'extends', 'implements', 'contains', 'all']. Document in parameter description.
• Explain project parameter format: 'Project name, absolute path, or auto-detect from current directory if omitted. E.g., '/home/user/myproject' or 'MyProject'.'
• Add bounds to maxFiles: 'Maximum files to analyze (1 - 50000, default: 5000). Larger values may increase analysis time.'
• Enhance error responses with recovery guidance. Example: Instead of 'Directory does not exist: /path', return { error: 'path_not_found', message: 'Directory not found: /path', suggestion: 'Check the path exists or call list_projects() to see available projects.' }.
