The server has 6 tools with moderate description quality but significant schema and parameter documentation gaps. Tool naming follows verb_noun conventions (ingest_document, retrieve, db_info, check_ollama, clear_db), which is good. However, most tools lack explicit input parameter type definitions visible in the source, schemas are not formally documented, and output schemas are entirely absent. The ingest_pdf tool is marked as deprecated, creating redundancy. Critical security and safety issues: clear_db is a destructive operation with no confirmation mechanism or permission gating. Error handling is present in code but not described in tool documentation. The descriptions are reasonable in length (most 50-150 chars) but lack actionable recovery guidance. Schema registration via fastmcp is likely present but not visibly detailed in the provided code excerpt.

• Add a confirm_clear_db tool or require a confirmation parameter (with enum: ['yes', 'no']) for clear_db. Document that this is irreversible.
• Explicitly document input schemas for all tools using JSON Schema format. Specify min/max for 'n' in retrieve (1-100), data types for all string parameters, and enums for choice parameters.
• Document the return/output schema for each tool. E.g., ingest_document returns {status: 'success'|'error', chunks_added: int, files_processed: int, files: [str]}.
• Remove ingest_pdf or mark it as hidden/internal. If kept, add a prominent deprecation notice in the description directing users to ingest_document.
• Enhance error messages with actionable recovery hints. E.g., 'Download failed: {exc}. Check that the URL is accessible and the file format is supported (PDF, DOCX, TXT, etc.).'
• Add parameter descriptions that include constraints inline. E.g., for retrieve 'n' parameter: 'Number of top chunks to retrieve (default 5, must be between 1 and 100).'
• Document which tools are read-only vs. write operations in their descriptions. Use explicit language: 'This operation modifies the database and cannot be undone.'
• Consider implementing a 'dry-run' parameter for ingest_document to preview what would be ingested without committing to the database.
• Add tool annotations (destructiveHint, readOnlyHint) if fastmcp supports them, to help clients/LLMs understand risk levels.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
