Instantdb MCP Server

Instantdb MCP MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. An MCP server for interacting with InstantDB.

What you get

This server provides a read-only interface for querying InstantDB using a dynamically loaded schema and environment configuration. It includes tools to execute queries and retrieve query examples based on pre-defined patterns.

Setting it up

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.

What the assistant can call

Once Instantdb MCP is connected, these are the calls the assistant has available:

• Tools — The Tools tool exposed by this server

Configuration and credentials

You will need 2 environment variables: INSTANT_APP_ID, INSTANT_APP_ADMIN_TOKEN. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Before you rely on it

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the instantdb mcp mcp server does with a few real requests.

Choosing this one

Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Instantdb MCP's toolset — Tools — is a fair guide to whether it matches your workflow. It is maintained by christophersutton; worth a glance at recent repository activity before you build anything load-bearing on it.
