PocketBase MCP Server

This is an MCP server that interacts with a PocketBase instance. It allows you to fetch, list, create, update, and manage records and files in your PocketBase collections.

Installation

1. Clone the repository (if you haven't already):

   git clone <repository_url>
   cd pocketbase-mcp
   

2. Install dependencies:

   npm install
   

3. Build the server:

   npm run build
   

   This compiles the TypeScript code to JavaScript in the build/ directory and makes the entry point executable.

Configuration

This server requires the following environment variables to be set:

• POCKETBASE_API_URL: The URL of your PocketBase instance (e.g., http://127.0.0.1:8090). Defaults to http://127.0.0.1:8090 if not set.
• POCKETBASE_ADMIN_TOKEN: An admin authentication token for your PocketBase instance. This is required. You can generate this from your PocketBase admin UI, see API KEYS.

These variables need to be configured when adding the server to Cline (see Cline Installation section).

Available Tools

The server provides the following tools, organized by category:

Migration System

The PocketBase MCP Server includes a comprehensive migration system for managing database schema changes. This system allows you to:

1. Create migration files with timestamped names
2. Generate migrations for common operations (creating collections, adding fields)
3. Apply and revert migrations individually or in batches
4. Track which migrations have been applied

Migration File Format

Migration files are JavaScript files with a timestamp prefix and descriptive name:

// 1744005374_update_transactions_add_debt_link.js
/// <reference path="../pb_data/types.d.ts" />
migrate((app) => {
  // Up migration code here
  return app.save();
}, (app) => {
  // Down migration code here
  return app.save();
});

Each migration has an "up" function for applying changes and a "down" function for reverting them.

Usage Examples

Setting a custom migrations directory:

await setMigrationsDirectory("./my_migrations");

Creating a basic migration:

await createNewMigration("add_user_email_index");

Creating a collection migration:

await createCollectionMigration({
  id: "users",
  name: "users",
  fields: [
    { name: "email", type: "email", required: true }
  ]
});

Adding a field to a collection:

await createAddFieldMigration("users", {
  name: "address",
  type: "text"
});

Applying migrations:

// Apply a specific migration
await applyMigration("1744005374_update_transactions_add_debt_link.js", pocketbaseInstance);

// Apply all pending migrations
await applyAllMigrations(pocketbaseInstance);

Reverting migrations:

// Revert a specific migration
await revertMigration("1744005374_update_transactions_add_debt_link.js", pocketbaseInstance);

// Revert to a specific point (exclusive)
await revertToMigration("1743958155_update_transactions_add_relation_to_itself.js", pocketbaseInstance);

// Revert all migrations
await revertToMigration("", pocketbaseInstance);

Cline Installation

To use this server with Cline, you need to add it to your MCP settings file (cline_mcp_settings.json).

1. Locate your Cline MCP settings file:

   • Typically found at ~/.config/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json on Linux/macOS.
   • Or ~/Library/Application Support/Claude/claude_desktop_config.json if using the Claude desktop app on macOS.

2. Edit the file and add the following configuration under the mcpServers key. Replace /path/to/pocketbase-mcp with the actual absolute path to this project directory on your system. Also, replace <YOUR_POCKETBASE_API_URL> and <YOUR_POCKETBASE_ADMIN_TOKEN> with your actual PocketBase URL and admin token.

   {
     "mcpServers": {
       // ... other servers might be listed here ...
   
       "pocketbase-mcp": {
         "command": "node",
         "args": ["/path/to/pocketbase-mcp/build/index.js"],
         "env": {
           "POCKETBASE_API_URL": "<YOUR_POCKETBASE_API_URL>", // e.g., "http://127.0.0.1:8090"
           "POCKETBASE_ADMIN_TOKEN": "<YOUR_POCKETBASE_ADMIN_TOKEN>"
         },
         "disabled": false, // Ensure it's enabled
         "autoApprove": [] // Default auto-approve settings
       }
   
       // ... other servers might be listed here ...
     }
   }
   

3. Save the settings file. Cline should automatically detect the changes and connect to the server. You can then use the tools listed above.
