This MCP server exhibits significant definition quality gaps. While three tools are defined with names and some schema structure, the implementation shows critical issues: (1) Tool definitions appear inferred from Rust code rather than explicit MCP registration, only the file location is provided, not the actual tool registration code; (2) Descriptions are present but generic and lack LLM-optimization guidance; (3) Input schemas are partially visible but lack rigor in parameter validation and error recovery; (4) No output schemas are documented; (5) Error handling is absent from tool definitions. The server targets research/investment analysis (alerts, pitch deck review) but does not demonstrate production-grade tooling patterns. The 'analyze_pitch_deck' tool accepts file uploads without explicit validation guidance, and 'run_alert_now' lacks pagination or result limiting documentation.

• Publish explicit MCP tool registration code showing schema, description, and input/output types. Use JSON Schema with minLength/maxLength, enum constraints, and pattern validation.
• Document output schemas for all three tools: save_alert returns {alert_id: string, name: string, cadence: string, enabled: boolean}; run_alert_now returns {results: [{title: string, url: string, summary: string}], result_count: number, next_cursor?: string}; analyze_pitch_deck returns {score: number, verdict: string, slides: [{number: number, feedback: string}], missing_evidence: string[], diligence_risks: string[], rewrite_checklist: string[]}.
• Add input validation and size constraints: analyze_pitch_deck file_data_base64 must be < 50MB; deck_notes must be 1-2000 chars. Specify explicit MIME type validation: 'application/pdf', 'application/vnd.openxmlformats-officedocument.presentationml.presentation', 'text/plain', 'text/markdown'.
• Implement pagination for run_alert_now: add optional limit (default 20, max 100) and cursor parameters. Return {results: [...], total_count: number, next_cursor?: string} to enable agent-driven iteration over large result sets.
• Add error recovery guidance to each tool description. Example: 'If alert name already exists, the error will suggest existing alerts. Try a unique name or update the existing alert.' Pattern: pattern:recovery-guide.
• Enhance 'cadence' enum description in save_alert with concrete timing: 'daily: runs every 24 hours at server time; weekly: runs every Monday 9 AM UTC; manual: runs only when run_alert_now is called.'
