Significant gaps across naming, descriptions, and schemas. Tool names lack consistent verb prefixes (health_check vs pocketbase_list_collections). Most descriptions are generic and under 100 chars, providing minimal LLM guidance. Input schemas present but sparse, many tools have empty property objects with no parameter descriptions. No output schemas documented. Error handling absent. Composition issues: duplicate tools (list_collections appears twice with different signatures). No tool annotations (readOnlyHint/destructiveHint). This server falls in the D-range: major issues that would require substantial rework for production use.

• Add output schemas to all tools. Example for pocketbase_list_records: {type: 'object', properties: {records: {type: 'array', items: {type: 'object'}}, total: {type: 'number'}, page: {type: 'number'}}}
• Expand descriptions to 50-200 chars with WHEN/WHY guidance. Current: 'Get comprehensive server status' (34 chars). Better: 'Retrieve server uptime, version, and active connection count. Call this first to verify PocketBase is running before attempting data operations.' (145 chars).
• Add descriptions to all parameters. Example for pocketbase_get_collection collectionId: 'Collection ID or name (string, 1-100 chars). Use pocketbase_list_collections to discover available IDs.'
• Consolidate duplicate list_collections tools into one canonical tool with optional includeSystem parameter. Remove the test-worker-tools.js version.
• Add tool annotations: mark all READ_ONLY tools with readOnlyHint: true; mark WRITE tools with destructiveHint: true and idempotentHint: false (unless they support idempotency keys).
