What is the Expo MCP server?

Connect Expo to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Speech Recognition for React Native Expo projects. The expo mcp server is what makes that connection.

What the server does

To configure androidSpeechServicePackages, add additional speech service packages here that aren't listed under the forceQueryable section when running the command: adb shell dumpsys package queries.

Installation

The server ships on npm as expo, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • Permissions — You should request permissions prior to starting recognition. This library exports two functions: getPermissionsAsync and requestPermissionsAsync for

Worth knowing first

  • 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.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Where it fits

Plenty of AI and media services 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. Expo's toolset — Permissions — is a fair guide to whether it matches your workflow. It is maintained by GitHub Actions; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
