Setup
Install InstantDB in your MCP client (Claude Desktop, Cursor, Windsurf, and others).
Repository: https://github.com/instantdb/instant
Follow the installation instructions in the repository README, then restart your MCP client.
- Create and manage InstantDB apps— use the Instant Platform SDK through MCP to build and update your applications directly from your editor.
- Query and modify your database— interact with your InstantDB data using the SDK methods exposed by the MCP server.
- Connect via remote or local server— use the hosted endpoint athttps://mcp.instantdb.comor run locally withnpx -y @instantdb/mcp.
This MCP is a wrapper around the Instant Platform SDK. Add this MCP to your editor to enable creating, managing, and updating your InstantDB applications.
Instant hosts the latest version of the server athttps://mcp.instantdb.com.
For modern clients that support streamable HTTP usehttps://mcp.instantdb.com/mcp.
For legacy clients that require SSE usehttps://mcp.instantdb.com/sse.
For more editor-specific instructions, seethe public docs.
If you haven't already, make sure to get apersonal access token from your Instant dashboard.
Run the server in stdio mode withnpx -y @instantdb/mcp --token <token>.
For more editor-specific instructions, seethe public docs.
Clone this repo and use the MCP Inspector@modelcontextprotocol/inspectorto debug and develop against this server locally.
# Clone this repo git clone .. # Navigate to the cloned directory and build the MCP server cd .. npm run build # Run the server npx @modelcontextprotocol/inspector node ./dist/index.js --token <token> # Or alternatively via environment variable INSTANT_ACCESS_TOKEN=<token> npx @modelcontextprotocol/inspector node ./build/index.js # You can also specify a url to connect to a local instance of your instant server npx @modelcontextprotocol/inspector node ./dist/index.js --token <token> --api-url http://localhost:8888
If you're using Claude Code you can add the mcp server directly after building:
claude mcp add --transport stdio instant-local -- node <path-to-your-cloned-repo>/dist/index.js --token <token>
You can then remove the server directly:
You can also configure your editor to connect to your local MCP. Here's an example configuration for MacOS/Linux:
{ "mcpServers": { "instant": { "command": "node", "args": [ "<path-to-your-cloned-repo>/dist/index.js", "--token", "<token>", "--api-url", "http://localhost:8888" ] } } }
Fill in all of the environment variables for your new.envfile.
Visit the server athttp://localhost:3123.
To work on thestdioversion of the codebase, update your.envfile withSERVER_TYPE=stdio.
