API, MCP and AI agents

MCP server

Connect https://uptime.rs/mcp to Claude, Cursor or any MCP client. Tools: check a website, read a certificate, look up a domain's expiry, TCP ping, and, with an API key, list, add, pause and read your monitors and incidents.

Agent skill

A ready SKILL.md that teaches an agent when and how to use uptime.rs. Download it and add it to your agent's skills.

Free tools API

GET /api/v1/tools/website, /ssl, /domain and /ping return JSON with no key, rate-limited per IP.

REST API and OpenAPI

Manage monitors, read checks, uptime and incidents, and post status page updates. The OpenAPI description is at /openapi.json; llms.txt summarises the site for language models.

Questions

Do I need an API key?

Not for the free tools (website, SSL, domain and ping checks). Managing monitors needs a key from Settings → API.

Which MCP transport is used?

Streamable HTTP at https://uptime.rs/mcp, answering JSON.
