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.

Compatibility

Component	Version
PocketBase server	>= v0.23 required (`_superusers` collection model); tested against v0.40.3 (latest stable at release time)
`pocketbase` JS SDK	^0.28.1
`@modelcontextprotocol/sdk`	^1.30.0
Node.js	>= 18

Notes for newer PocketBase servers:

v0.27+: the geoPoint field type and the geoDistance() filter function are fully supported by list_records / batch_records — see Filter examples with geoPoint.
v0.40.x: Log.Data may be truncated by the server (~16KB) and marked with "__pb_truncated__": true; log messages are limited to 8KB. list_logs / get_log output passes this through as-is.
v0.38+: a superuser IP whitelist can be enabled in PocketBase Settings. When active, requests from IPs outside the whitelist (including this MCP's token) are rejected with HTTP 403 — see Troubleshooting.
v0.33+: collection/record ids may not contain . / \ | " ' ` < > : ? * % $ or Windows reserved names. The migration generators validate this up front.
v0.28+: the json field type has a default maximum size of 1MB; larger payloads fail validation on create_record / update_record.

Installation

Installing via Smithery

To install PocketBase MCP Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @mabeldata/pocketbase-mcp --client claude

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

git clone <repository_url>
cd pocketbase-mcp

Install dependencies:
```
npm install
```
Build the server:
```
npm run build
```
This compiles the TypeScript code to JavaScript in the build/ directory and makes the entry point executable.

Testing

Test suite (vitest, 3 layers — full guide in tests/TESTS.md):

npm test — unit + contract tests (207: 195 passing + 12 documented known-bug markers; hermetic: no PocketBase instance or network required). The contract layer locks the tools/list MCP contract via snapshot (33 tools: the 22 original + 11 additive PR-3 tools, each group snapshotted separately), a real Client↔Server handshake over InMemoryTransport, and a stdio smoke of the built build/index.js.
npm run test:integration — integration tests against a real PocketBase binary (56 tests): auto-downloads/caches the binary (POCKETBASE_VERSION to pin, POCKETBASE_BIN for a local binary, PB_BIN_DIR for an alternative cache), boots an ephemeral instance on an OS-assigned port with a unique superuser identity, and validates generated migration files with the official migrate up/down runner. The PR-3 suite (pr3-tools.test.ts) boots its own dedicated instance (admin-scope endpoints — SQL, batch, backups, settings, log clear — must not race siblings on the shared server; see the file header).
npm run test:all — the full suite (263 tests).
npm run typecheck — tsc over src + tests.
SKIP_KNOWN_BUG_TESTS=1 npm test — green baseline where known-bug marker tests are skipped instead of run.

End-to-end smoke scripts (drive the built server over stdio against a real PocketBase instance, 53 checks):

npm run smoke:contract — contract-only smoke (tools/list over stdio, no PocketBase needed).
npm run smoke — full smoke: starts an ephemeral server from the binary at $POCKETBASE_BIN (default /tmp/pb-bin/pocketbase), creates a superuser, then exercises every tool category (records, collections, files, logs, crons, migrations) over the stdio JSON-RPC channel.

CI (.github/workflows/ci.yml) runs build + typecheck + hermetic tests + integration tests + smoke on a matrix of Node 18/20/22 × PocketBase v0.39.11/v0.40.3.

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.
POCKETBASE_ENABLE_SQL: Optional, default disabled. Gates the run_sql tool (raw SQL execution). See SQL Execution (run_sql) below — only set it to true if you understand the risks.

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

  ]
}

batch_records: Execute multiple record operations (create/update/upsert/delete) in ONE transactional batch — if any operation fails, the whole batch rolls back. Requires server-side batch enabled: on PocketBase >= v0.39 /api/batch is OFF by default; enable it via update_settings with {"batch": {"enabled": true}} (or Admin UI -> Settings), otherwise calls fail with HTTP 403 "Batch requests are not allowed".

Input Schema:

{
  "type": "object",
  "properties": {
    "requests": {
      "type": "array",
      "items": {

download_file: Get the download URL for a file stored in a PocketBase collection record.

Input Schema:

{
  "type": "object",
  "properties": {
    "collection": {
      "type": "string",
      "description": "The name of the PocketBase collection."
    },

    "recordId",
    "fileField"
  ]
}

Note: This tool returns the file URL. The actual download needs to be performed by the client using this URL.

Filter examples: geoPoint

PocketBase >= v0.27 supports the geoPoint field type and the geoDistance() filter function. Both work transparently through list_records / create_record / update_record / batch_records (the filter string is passed to the server as-is):

// store a location: create_record data payload (location is a geoPoint field)
{ "title": "Office", "location": { "lat": -23.5505, "lon": -46.6333 } }

// geoDistance(lonA, latA, lonB, latB) returns KILOMETRES (verified on v0.40.3) —
// offices within 10 km of São Paulo center (list_records filter):
{ "collection": "places", "filter": "geoDistance(location.lon, location.lat, -46.6333, -23.5505) <= 10" }

// combine with other conditions:
{ "collection": "places", "filter": "active = true && geoDistance(location.lon, location.lat, -46.6333, -23.5505) < 5" }

Arguments must be plain numbers or numeric field identifiers (location.lon / location.lat for a geoPoint field); a geometry-literal like {-23.55, -46.63} is NOT valid, and geoDistance() is currently not supported in sort. Official docs: https://pocketbase.io/docs/api-rules-and-filters/ (geoDistance section).

Collection Management

list_collections: List all collections in the PocketBase instance.
- Input Schema:
```
{
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
```

get_collection_schema: Get the schema of a PocketBase collection.

Input Schema:

{
  "type": "object",
  "properties": {
    "collection": {

    }
  },
  "required": [
    "collection"
  ]
}

get_collection_scaffolds: Get example collection schema payloads (server >= v0.37) — an object keyed by collection type (base, auth, view) with ready-to-edit templates for building new collections.
- Input Schema: { "type": "object", "properties": {}, "additionalProperties": false }
dry_run_view_query: Validate a VIEW collection SQL query without saving the collection (server >= v0.37). Returns the resulting field definitions and a sample of rows, or a validation error.
- Input Schema:
```
{
  "type": "object",
  "properties": {
    "query": { "type": "string", "description": "The SQL SELECT statement backing the view collection." }
  },
  "required": ["query"]
}
```

Log Management

Note: The Logs API requires admin authentication and may not be available in all PocketBase instances or configurations. These tools interact with the PocketBase Logs API as documented at https://pocketbase.io/docs/api-logs/.

list_logs: List API request logs from PocketBase with filtering, sorting, and pagination.

Input Schema:

{
  "type": "object",
  "properties": {
    "page": {
      "type": "number",
      "description": "Page number (defaults to 1).",
      "minimum": 1
    },
    "perPage": {
      "type": "number",
      "description": "Items per page (defaults to 30, max 500).",
      "minimum": 1,
      "maximum": 500
    },
    "filter": {
      "type": "string",
      "description": "PocketBase filter string (e.g., \"method='GET'\")."
    },
    "sort": {
      "type": "string",
      "description": "PocketBase sort string (e.g., \"-created,url\")."
    }
  },
  "required": []
}

Note: on PocketBase >= v0.40 the server may truncate Log.Data (~16KB, marked with "__pb_truncated__": true) and limit log messages to 8KB.

get_log: Get a single API request log by ID.

Input Schema:

{
  "type": "object",
  "properties": {
    "id": {
      "type": "string",
      "description": "The ID of the log to fetch."
    }
  },
  "required": [
    "id"
  ]
}

get_logs_stats: Get API request logs statistics with optional filtering.

Input Schema:

{
  "type": "object",
  "properties": {
    "filter": {
      "type": "string",
      "description": "PocketBase filter string (e.g., \"method='GET'\")."
    }
  },
  "required": []
}

truncate_logs: Delete ALL API request logs (server >= v0.40). DESTRUCTIVE and irreversible — requires confirm: true.

Input Schema:

{
  "type": "object",
  "properties": {
    "confirm": { "type": "boolean", "description": "Must be explicitly true to delete all logs." }
  },
  "required": ["confirm"]
}

Cron Job Management

Note: The Cron Jobs API requires admin authentication and may not be available in all PocketBase instances or configurations. These tools interact with the PocketBase Cron Jobs API.

list_cron_jobs: Returns list with all registered app level cron jobs.

Input Schema:

{
  "type": "object",
  "properties": {
    "fields": {
      "type": "string",
      "description": "Comma separated string of the fields to return in the JSON response (by default returns all fields). Ex.:?fields=*,expand.relField.name"
    }
  }
}

run_cron_job: Triggers a single cron job by its id.

Input Schema:

{
  "type": "object",
  "properties": {
    "jobId": {
      "type": "string",
      "description": "The identifier of the cron job to run."
    }
  },
  "required": [
    "jobId"
  ]
}

Backup Management

Note: The Backup API requires superuser authentication (server >= v0.22). Docs: https://pocketbase.io/docs/api-backups/.

list_backups: List all backup files available on the instance (key, size, modified).
- Input Schema: { "type": "object", "properties": {}, "additionalProperties": false }
create_backup: Queue a new database+storage backup. Optional name must end in .zip (letters, digits, _, - only); omitted → the server generates pb_backup_<timestamp>.zip. Backups are processed asynchronously — poll list_backups for the new key.
- Input Schema:
```
{
  "type": "object",
  "properties": {
    "name": { "type": "string", "description": "Optional backup filename ending in .zip." }
  },
  "required": []
}
```

restore_backup: Restore the instance from an existing backup key. DESTRUCTIVE: replaces ALL current data. Requires confirm: true.

Input Schema:

{
  "type": "object",
  "properties": {
    "key": { "type": "string", "description": "Backup file key from list_backups." },
    "confirm": { "type": "boolean", "description": "Must be explicitly true." }
  },
  "required": ["key", "confirm"]
}

Settings Management

Note: The Settings API requires superuser authentication. Secrets (SMTP password, S3 keys, OAuth2 client secrets) are returned by the server masked as "******"; update_settings needs the REAL new values for those fields (PATCH semantics — omitted fields keep their stored values).

get_settings: Fetch all app settings (sections: meta, logs, smtp, batch, backups, s3, rateLimits, ...).
- Input Schema: { "type": "object", "properties": {}, "additionalProperties": false }

update_settings: Bulk-update settings with a partial payload.

Input Schema:

{
  "type": "object",
  "properties": {
    "data": { "type": "object", "description": "Partial settings payload, e.g. { \"logs\": { \"maxDays\": 14 } }.", "additionalProperties": true }
  },
  "required": ["data"]
}

SQL Execution (run_sql — security gated)

run_sql executes arbitrary raw SQL against the PocketBase instance (server >= v0.39, endpoint POST /api/sql) with superuser privileges. Because an MCP server is typically driven by an LLM — and LLMs can be steered by prompt injection in the data they read — this tool is a much bigger blast radius than the record-level tools and is therefore:

DISABLED BY DEFAULT. The tool is always listed (stable contract), but every call returns an explanatory error unless the MCP process was started with POCKETBASE_ENABLE_SQL=true. No network request is made when the gate is closed.
All-or-nothing. There is no read-only mode: SQL statements that modify or drop data (UPDATE, DELETE, DROP, PRAGMAs, ...) are just as executable as SELECT. Only enable the gate on instances you fully trust and, ideally, on a copy of your data (PocketBase is a single file — back it up first with create_backup).
Auditable. SQL calls land in the PocketBase request logs (POST /api/sql), so list_logs can reconstruct what ran.

Enable explicitly, only if you accept the risks:

POCKETBASE_ENABLE_SQL=true node build/index.js

Typical (read-only) usage once enabled:

{ "name": "run_sql", "arguments": { "query": "SELECT COUNT(*) AS n FROM posts" } }

Migration System

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

Create migration files with timestamped names
Generate migrations for common operations (creating collections, adding fields)
Apply and revert migrations individually or in batches

How apply/revert works (and its limits)

Migration files generated by this MCP (create_collection_migration, add_field_migration) embed a machine-readable marker comment (// mcp-migration-meta: {...}) describing their operations as plain data. apply_migration, revert_migration, apply_all_migrations and revert_to_migration execute those operations through the PocketBase REST API (pb.collections.*), which is the only channel available to an MCP client.

Migration files without the marker — e.g. hand-written server-side JSVM migrations created with ./pocketbase migrate create — use the server JSVM API (migrate(), new Collection(), app.save()), which does not exist in a REST client. They cannot be applied through this MCP; the apply tools return an explanatory error pointing to ./pocketbase migrate up on the PocketBase host. (Previous versions tried to evaluate those files locally with new Function, which always failed at runtime.)

Applied-state tracking is not stored server-side: apply_all_migrations / revert_to_migration take an appliedMigrations array parameter (the server's _migrations table is not exposed to REST clients). Keep that list in your own tooling, or apply/revert individual files.

Generated files remain valid JSVM migrations, so the same file can also be applied on the host with ./pocketbase migrate up (in which case PocketBase tracks the state in its own _migrations table — do not mix both execution paths for the same file).

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" />
// mcp-migration-meta: {"ops":{"up":[...],"down":[...]}}   <- only in MCP-generated files
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

Cline Installation

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

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.

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": [
        "fetch_record",
        "list_collections",
        "get_collection_schema",
        "list_logs",
        "get_log",
        "get_logs_stats",
        "list_cron_jobs",
        "run_cron_job"
      ] // Suggested auto-approve settings
    }

    // ... other servers might be listed here ...
  }
}

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

Troubleshooting

HTTP 403 on every request: since PocketBase v0.38 you can enable a superuser IP whitelist (Admin UI -> Settings). If enabled, add the IP of the machine running this MCP server (or disable the whitelist).
FATAL: POCKETBASE_ADMIN_TOKEN environment variable is required: the token env var is not set; generate an API key in the PocketBase admin UI (superuser -> API keys) and set POCKETBASE_ADMIN_TOKEN.
Health-check warning on stderr at startup: the configured POCKETBASE_API_URL is unreachable (instance down or wrong URL). The MCP still starts so tools/list works, but tool calls will fail until the instance is reachable.
Cannot apply ...: This migration file does not contain MCP metadata: the file is a server-side JSVM migration; run ./pocketbase migrate up on the PocketBase host instead (see Migration System).
