Manual configuration (.mcp.json)

Add to your .mcp.json file:

{
  "mcpServers": {
    "grist": {
      "command": "npx",
      "args": ["-y", "grist-mcp-server"],
      "env": {
        "GRIST_API_KEY": "your_api_key",
        "GRIST_BASE_URL": "https://docs.getgrist.com"
      }
    }
  }
}

Install from source

git clone https://github.com/gwhthompson/grist-mcp-server.git
cd grist-mcp-server
npm install && npm run build

Add to your MCP config:

{
  "mcpServers": {
    "grist": {
      "command": "node",
      "args": ["/path/to/grist-mcp-server/dist/index.js"],
      "env": {
        "GRIST_API_KEY": "your_api_key",
        "GRIST_BASE_URL": "https://docs.getgrist.com"
      }
    }
  }
}

Cloudflare Workers (HTTP transport)

Deploy as a remote MCP server using Cloudflare Workers for HTTP-based access.

Local development:

npm run worker:dev

Deploy to Cloudflare:

npm run worker:deploy

Configuration:

The Workers deployment uses header-based authentication:

• X-Grist-API-Key: Your Grist API key (required)
• X-Grist-Base-URL: Grist instance URL (optional, defaults to https://docs.getgrist.com)

Endpoint: https://your-worker.workers.dev/mcp

Example request:

curl -X POST https://your-worker.workers.dev/mcp \
  -H "Content-Type: application/json" \
  -H "X-Grist-API-Key: your_api_key" \
  -d '{"jsonrpc":"2.0","method":"tools/list","id":1}'

Notes:

• Stateless design: Each request creates a fresh server instance
• CORS enabled for all origins (safe because auth uses headers, not cookies)
• Configure environment variables via wrangler secret put GRIST_API_KEY

Tools

Examples

Create a database

1. grist_get_workspaces → find workspace
2. grist_create_document → create document
3. grist_manage_schema → create tables with columns

Import data

1. grist_get_documents → find document
2. grist_get_tables → check structure
3. grist_manage_records → upsert data (adds new, updates existing)

Query data

1. grist_get_tables → understand schema
2. grist_query_sql → run SQL with JOINs and aggregations

Troubleshooting

Server won't start: Check GRIST_API_KEY is set in config.

Authentication fails: Verify API key at https://docs.getgrist.com/settings/keys.

Empty document list: Check GRIST_BASE_URL matches your Grist instance.

Connection errors (self-hosted): Verify URL includes https:// and server is reachable.

Testing

npm test  # Docker required - container lifecycle is automatic
