Claude Desktop
Use Sigment in the Claude desktop app.
Claude Desktop shares connectors with claude.ai. Add Sigment once, as described in Claude (claude.ai), and it appears in the desktop app too. You can also add it from Settings → Connectors → Add custom connector in the app.
Don't add Sigment to claude_desktop_config.json: that file is for local (stdio) servers, and Sigment is a remote server.
After connecting, approve the agent in Sigment → Settings → AI agents.
