    unique: true
  }
});

Advanced Querying

// Query with filtering, sorting, and aggregation
await mcp.use_tool("pocketbase", "query_collection", {
  collection: "posts",

Error Handling

All tools include comprehensive error handling with detailed error messages. Errors are properly typed and include:

• Invalid request errors
• Authentication errors
• Database operation errors
• Schema validation errors
• Network errors

Type Safety

The server includes TypeScript definitions for all operations, ensuring type safety when using the tools. Each tool's input schema is strictly typed and validated.

Best Practices

1. Always use proper error handling with try/catch blocks
2. Validate data before performing operations
3. Use appropriate indexes for better query performance
4. Regularly backup your database
5. Use migrations for schema changes
6. Follow security best practices for user management
7. Monitor and optimize database performance

Development

1. Clone the repository
2. Install dependencies: npm install
3. Copy .env.example to .env and configure
4. Build: npm run build
5. Start your PocketBase instance
6. The MCP server will automatically connect to your PocketBase instance
