Usage Examples

Collection Management

// Create a new collection
await mcp.use_tool("pocketbase", "create_collection", {
  name: "posts",
  schema: [
    {
      name: "title",
      type: "text",
      required: true
    },
    {
      name: "content",
      type: "text",
      required: true
    }
  ]
});

// Manage indexes
await mcp.use_tool("pocketbase", "manage_indexes", {
  collection: "posts",
  action: "create",
  index: {
    name: "title_idx",
    fields: ["title"],
    unique: true
  }
});

Advanced Querying

// Query with filtering, sorting, and aggregation
await mcp.use_tool("pocketbase", "query_collection", {
  collection: "posts",
  filter: "created >= '2024-01-01'",
  sort: "-created",
  aggregate: {
    totalLikes: "sum(likes)",
    avgRating: "avg(rating)"
  },
  expand: "author,categories"
});

Data Import/Export

// Import data with upsert mode
await mcp.use_tool("pocketbase", "import_data", {
  collection: "posts",
  data: [
    {
      title: "First Post",
      content: "Hello World"
    },
    {
      title: "Second Post",
      content: "More content"
    }
  ],
  mode: "upsert"
});

// Backup database
await mcp.use_tool("pocketbase", "backup_database", {
  format: "json" // or "csv"
});

Schema Migration

            
        
            
                // Migrate collection schema
await mcp.use_tool("pocketbase", "migrate_collection", {
  collection: "posts",
  newSchema: [
    {
      name: "title",
      type: "text",
      required: true
    },
    {
      name: "content",
      type: "text",
      required: true
    },
    {
      name: "tags",
      type: "json",
      required: false
    }
  ],
  dataTransforms: {
    // Optional field transformations during migration
    tags: "JSON.parse(oldTags)"
  }
});

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
