Expo does not always answer

Over the last week it answered 99.1% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 25

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

expo
expo_add_library
Add an Expo library to the project using expo install and attach usage instructions when available
expo_build_cancel
Cancels an EAS build that is queued or in progress. Use build_info to check the current status first.
expo_build_info
Fetches the status and detailed information about a specific EAS build by ID. Use this to check build status, errors, artifacts, and other details.
expo_build_list
Lists EAS builds for a project. Provide either appId (from app.json "extra.eas.projectId") OR appFullName (e.g., "@owner/my-app"). Use this to see recent builds, their status, and available artifacts.
expo_build_logs
Fetches the logs for a specific EAS build. The build must be completed (finished or errored) to have logs available.
expo_build_run
Triggers a new EAS build using a build profile from eas.json. Requires a GitHub repository to be connected to the project. Provide either appId (from app.json "extra.eas.projectId") OR appFullName (e.g., "@owner/my-app").
expo_build_submit
Submits an EAS build to the app store (Google Play Store for Android, App Store for iOS). The build must be a finished build with the appropriate distribution type. Provide either appId (from app.json "extra.eas.projectId") OR appFullName (e.g., "@owner/my-app").
expo_learn
Learn Expo how-to for a specific topic and remember it for future conversations. Use this to teach the assistant about specific Expo features or workflows.
expo_read_documentation
Fetch a single Expo documentation page and return its content as markdown. Returns up to ~5000 tokens per call. Use offset to paginate through long pages.
expo_search_documentation
Search the official Expo documentation and return page URLs ranked by relevance for a user query. Use read_documentation to fetch the full content of specific pages, starting from the top.
expo_testflight_crashes
Fetch TestFlight crash data. Without crashId, lists recent crashes. With crashId, returns the full crash log with stack trace.
expo_testflight_feedback
Fetch screenshot feedback from TestFlight. Returns feedback metadata including device info, user comments, and screenshot URLs.
expo_workflow_cancel
Cancels a running EAS workflow. Use workflow_info to get the workflow run ID.
expo_workflow_create
Creates a new EAS workflow YAML file for Expo projects or fetches workflow syntax documentation. Use this when users want to create CI/CD workflows in .eas/workflows/ or need to learn EAS workflow syntax. After creating, use workflow_validate to validate the file.
expo_workflow_info
Fetches detailed information about a specific EAS workflow run by ID. Use this to check the status, job results, errors, and artifacts of a workflow run. If workflow has multiple jobs, draw them in a diagram to show the dependencies between jobs.
expo_workflow_list
Lists recent EAS workflow runs for a project. Provide either appId (from app.json "extra.eas.projectId") OR appFullName (e.g., "@owner/my-app").
expo_workflow_logs
Fetches logs for a specific job in an EAS workflow run. Call without sectionIndex or phase to get a summary of log sections (phase names and line ranges); then call again with sectionIndex or phase to fetch that section.
expo_workflow_run
Triggers an EAS workflow run from a git reference. Provide either appId (from app.json "extra.eas.projectId") OR appFullName (e.g., "@owner/my-app"). The workflow file must exist at the specified git reference.
expo_workflow_validate
Validates EAS workflow YAML syntax and configuration. Use this after creating a workflow to ensure it is valid. Provide either appId (from app.json "extra.eas.projectId") OR appFullName (e.g., "@owner/my-app").
authenticate
authenticate
MCP.AI for IDE agents (Cursor, etc.): log in in the browser, copy the access token. Best: add it to this server's config as a header `Authorization: Bearer <token>` for a permanent, non-expiring connection. Or paste it here for a session-only login: call with { token: "<jwt>" } after the user pastes, or with no args to get the link.
connect
connect
Returns connection status and URLs. When all providers are connected, returns authenticated:true and empty pending[]. When credentials are missing, returns connect_url for the toolkit and per-install URLs.
marketplace
marketplace
The official mcp.ai marketplace — the in-platform catalog of every MCP/tool, AND the way to run them. Covers capability requests like "find an MCP that does X", "consulta um CPF", "is there a tool for Y". Core flow: action=search discovers MCPs by intent → describe returns one MCP's full profile (every tool with its id + params, pricing, auth) so you pick the right tool_id → invoke RUNS that tool. KEY: invoke works even when the MCP is NOT installed — it runs the tool pontualmente (one-off), without adding the MCP to the toolkit and without bloating the tool list. If the MCP needs a credential/login, invoke returns a connect link; if it is paid and the wallet is empty, invoke returns a checkout/top-up link (the user opens it, then you retry). Use install only to make an MCP PERMANENT in the active toolkit (its tools then show up natively in future sessions); prefer invoke for a single/occasional use. list_tools lists what is callable right now. subscribe/cancel handle per-MCP billing; report_bug sends feedback; request_mcp asks us to build a NEW MCP when nothing fits. Search/describe flag installed_in_toolkit vs installed_in_workspace. Writes (install/uninstall/subscribe/cancel and the one-off install behind invoke) require workspace owner/admin. It also carries the mcp.ai PROMPT LIBRARY, which is about ready-made prompt TEXT rather than MCPs: search_prompts finds one, get_prompt returns its full text with {{variables}} filled, and publish_prompt saves a prompt and returns a shareable mcp.ai/p/<slug> link that opens without login.
report
report_bug
Report a bug, missing feature, or send feedback. Include the conversation array with recent messages for reproduction.
show
show_version
Show the current MCP platform and adapter versions.
toolkit
toolkit_info
Returns the current toolkit state: installed MCPs, their connection status, the accounts connected to each one, and how many catalog tools each exposes.

Expo — questions

Answers built from our own checks of this server.

What can Expo do?
It exposes 25 tools, read directly from the server on our last check. Among them: authenticate, connect, expo_add_library, expo_build_cancel, expo_build_info, expo_build_list and 19 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Expo working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 1046 ms. The bar chart above shows every period we have measured.
How do I connect Expo?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Expo need an API key?
No. Expo completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 25 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Expo?
It answers our handshake in 1046 ms on average, which is faster than 8% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Expo open source?
Yes — it is published under the MIT licence and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
