Developer platforms - official Expo server
Expo MCP server
Hosted MCP server from Expo that gives AI tools Expo documentation, dependency installs, EAS build and workflow management, TestFlight, App Store and Google Play data. Optional local capabilities (screenshots, taps, DevTools, logs) are added through the expo-mcp dev dependency and a local Expo dev server. Expo hosts it at https://mcp.expo.dev/mcp, or you can run expo-mcp (npm) locally with OAuth auth.

As documented on October 17, 2026. A running server reports its current list through tools/list.
Notes and caveats
- Requires an Expo account and a project on the latest Expo SDK. search_documentation requires an EAS paid plan.
- Local capabilities need SDK 54 or later, the expo-mcp dev dependency (npx expo install expo-mcp --dev) and starting the dev server with EXPO_UNSTABLE_MCP_SERVER=1 npx expo start; the client must reconnect whenever the dev server starts or stops. iOS local capabilities are simulator-only and macOS-only; one dev server connection at a time.
- VS Code setup is documented as UI steps only (MCP: Add Server > HTTP > https://mcp.expo.dev/mcp, name expo).
- The expo/expo-mcp repo (MIT) holds the local capabilities provider (npm expo-mcp, latest 0.2.4); the hosted server itself is not open source, and the repo has no GitHub releases.
- Also available as a Claude connector and registered automatically by the expo plugin for Claude Code and Codex.

Transport: stdioAuth: No auth - Chroma
Package Search MCP server
Remote MCP server, hosted by Chroma, that gives coding agents grep, hybrid semantic search and file reads over the source code of thousands of public packages Chroma has indexed, so they can ground code in the real dependency source.
Transport: Streamable HTTPAuth: API key - Chromatic
Chromatic published Storybook MCP server
Chromatic deploys a project's Storybook MCP server alongside each published Storybook at its /mcp route, with Chromatic access control, so teams and agents can query component documentation remotely without running Storybook locally.
