Exit1 Uptime Monitoring

exit1-mcp

MCP server for Exit1 uptime monitoring. Let your AI assistant set up monitoring for the project you just shipped — read your repo, create the checks, configure alerts, and send a real test alert to prove it works — then ask it about uptime in plain language afterwards.

Two ways to connect

Hosted (recommended). No API key, no npm install, no plan requirement to get started. Run this in your terminal before starting a session: the login opens your browser, you sign in (or sign up) with Clerk, approve, and you're connected.

claude mcp add --transport http exit1 https://app.exit1.dev/mcp/v1 && claude mcp login exit1

One line on purpose: pasting the two commands as separate lines is unreliable in some terminals (cmd.exe drops the second line). In old Windows PowerShell (5.1), where && doesn't parse, run the two halves one at a time. Connect before you start the session: MCP clients load servers at startup, so a server added mid-conversation isn't usable until a restart. On Claude Code versions without claude mcp login, start claude and authenticate via /mcp instead.

Local stdio. This npm package. Uses a Public API key from your dashboard. Use it when your client doesn't support remote MCP servers with OAuth.

claude mcp add exit1 -- npx -y exit1-mcpexport EXIT1_API_KEY="ek_live_your_key_here"

Both expose the same tools. The hosted server is easier; the stdio one has no browser step, which some CI-ish setups prefer.

No account yet? Let the agent create one

Started without EXIT1_API_KEY, the stdio server doesn't exit. It starts in setup mode and offers one extra tool, create_account. Your agent calls it with your email address, and exit1 creates a free account and connects the server to it on the spot. Every other tool works straight away, and monitors start running.

claude mcp add exit1 -- npx -y exit1-mcp# then, in the session: "Set up uptime monitoring for this project with exit1. My email is [email protected]."

Or from a terminal, before the session:

npx exit1-mcp signup --email [email protected]

Either way exit1 emails you a link to claim the account. Alerts are only delivered once you claim it, so nobody can point exit1's alerts at an address they don't own. On the claim page you decide whether the agent keeps access. Unclaimed accounts are paused after 7 days and deleted after 30.

The tokens are saved to ~/.exit1/credentials.json and refreshed automatically, so later sessions connect without any setup. EXIT1_API_KEY, when set, always wins. Agents that don't use MCP can do the same with one HTTP call: see Agent signup.

Zero to monitored

Connect the server (above), then paste this into Claude Code, Cursor, Codex or any MCP-capable assistant, from inside your project:

Set up uptime monitoring for this project with Exit1.
1. Call get_account to see my plan limits. If you have a create_account tool   instead, I have no account yet: ask for my email and call it. If the Exit1   tools aren't available to you at all, don't try to connect from inside this   session; tell me to add the HTTP MCP server https://app.exit1.dev/mcp/v1 in   my tool, restart it, and paste this prompt again.2. Read this repo to find what should be monitored: deployed URLs in vercel.json /   next.config / wrangler.toml / .env.production / README, and any /health or   /api/status route handlers.3. Show me the checks you plan to create before creating them.4. Configure email alerts, then send a test alert so I can confirm delivery works.

Once connected, the server also ships a setup_monitoring prompt containing the full playbook — in Claude Code, /exit1:setup_monitoring.

Requirements

• Hosted: an Exit1 account. Sign-up happens inline during the OAuth flow.
• Local stdio: Node.js 18+, and either an API key from your dashboard (every plan can mint one, Free included) or no account at all: see No account yet?.

Supported clients

Remote MCP with OAuth is still rolling out across clients. Where it isn't supported yet, the stdio path below works everywhere.

Local stdio setup

Claude Code

claude mcp add exit1 -- npx -y exit1-mcp
export EXIT1_API_KEY="ek_live_your_key_here"claude

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{  "mcpServers": {    "exit1": {      "command": "npx",      "args": ["-y", "exit1-mcp"],      "env": {        "EXIT1_API_KEY": "ek_live_your_key_here"      }    }  }}

Cursor

Add to .cursor/mcp.json in your project (or ~/.cursor/mcp.json globally). Same shape as Claude Desktop above.

VS Code with Copilot

Run MCP: Add Server from the Command Palette, choose Command (stdio), enter npx -y exit1-mcp. VS Code uses a servers key rather than mcpServers:

{  "servers": {    "exit1": {      "command": "npx",      "args": ["-y", "exit1-mcp"],      "env": {        "EXIT1_API_KEY": "ek_live_your_key_here"      }    }  }}

Windsurf / Gemini CLI / Goose

Same mcpServers block as Claude Desktop, in mcp_config.json (Windsurf settings › MCP), ~/.gemini/settings.json, or via goose mcp add exit1 -- npx -y exit1-mcp. Restart the IDE or CLI afterwards.

Codex CLI

codex mcp add exit1 -- npx -y exit1-mcpexport EXIT1_API_KEY="ek_live_your_key_here"codex

ChatGPT

Bridge the stdio server with mcp-remote, then add it under Settings › Connectors.

Tools

The hosted server requests checks:read, checks:write, alerts:read and alerts:write by default — not checks:delete, which has to be asked for explicitly. For the stdio path, tick the scopes you want when creating the API key.

Example prompts

• "Set up monitoring for this project."
• "Are any of my monitors down right now?"
• "What's the uptime for my API check over the last 30 days?"
• "Show me the last 10 failures for production."
• "Add a check on staging.example.com and send alerts to #ops in Slack."
• "Compare response times this week vs last week."

Configuration

Managing connections

Hosted connections are listed at app.exit1.dev/mcp and can be revoked there at any time. Revoking kills every token issued to that client immediately.

Development

npm installnpm run build          # tsc -> dist/npm test               # build, then drive a real MCP handshake over stdionpm run check:catalog  # compare the tool catalog against the hosted server

npm test spawns the built server and asserts the surface a client actually sees: the tool count, readOnlyHint / destructiveHint annotations, the setup_monitoring prompt, and that an unknown tool returns isError rather than a protocol error. A second run starts it with no key and no saved credentials and checks setup mode (create_account listed, other tools explain how to get an account). It needs no API key and makes no network calls.

Why check:catalog exists

The tool catalog is deliberately duplicated between this package and the hosted OAuth server, which lives in Mopra/exit1.dev at functions/src/mcp-tools.ts. Two separate builds, no shared package, nothing at compile time tying them together. npm run check:catalog fails if they drift on tool names or input schemas, and warns on wording differences. CI runs it on every push and once a day.

Change a tool here, change it there — and run the check before releasing.

To run it against a local checkout instead of GitHub:

CATALOG_REMOTE_PATH=../exit1.dev/functions/src/mcp-tools.ts npm run check:catalog

Releasing

npm version patch          # or minornpm publish                # prepublishOnly runs the build + smoke testgit push --follow-tags

Bump version in server.json to match, then re-publish the registry entry (see below). The version string in src/index.ts is what clients see in serverInfo — keep it in step with package.json.

MCP registry

server.json describes both distribution paths (the npm package and the hosted endpoint) for the official MCP registry. The registry name is dev.exit1/exit1-mcp, which requires proving control of exit1.dev:

mcp-publisher login dns --domain=exit1.dev --private-key=HEX_KEYmcp-publisher publish

npm ownership is proven by the mcpName field in package.json, which must stay equal to name in server.json.

Quick Links

Also listed on the official MCP registry as dev.exit1/exit1-mcp.

The rest of exit1 is source-available rather than open source; this package is the exception, so it can be vendored and inspected freely by MCP clients.
