Hosted MCP, one-click connect
A hosted MCP endpoint at mcp.katto.tech with browser sign-in, so you connect Katto to Claude, ChatGPT and Cursor by adding a single URL, with no install and no API key to paste.
Connect Katto to Claude, ChatGPT or Cursor by pasting one URL: mcp.katto.tech. No install, no package to add, no API key to copy into a config file.
Sign in happens in your browser, through OAuth 2.1 with PKCE. Your key never touches the client: the consent page hands a short lived grant to our server, and the server holds the credential. A client you connect today can be disconnected tomorrow without rotating anything.
The same URL still accepts an sk_live_ key in a header, so the integrations built before this existed kept working the day it shipped. One endpoint, two ways in, no migration.
Sixteen tools are exposed, and the three copies of that list, the npm package, the hosted worker and the internal registry, are checked against each other in CI. A tool that drifts between them fails the build rather than reaching you.
2 videos a month, no card. What is still being built is on the roadmap.
