No public changelog for the API or the MCP server.\n\n**Mumble.** Mumble keeps audio on the Mac and stores each conversation as plain files in ~/Mumble, with canvas JSON that diffs cleanly. There is no API or MCP server an outside agent can call today. The documented `mumble-mcp` has no public download, package or repository, and the app is reached only through an early-access waitlist.\n\n## Before you call either\n\n### Lucid API + MCP\n\n1. Always send `Lucid-Api-Version: 1`, or prefix the path with /v1\n2. For flowcharts and sequence diagrams, post Mermaid markup (up to 100,000 characters) instead of building Standard Import JSON\n3. Request `:readonly` scopes when the agent only reads documents\n4. On 429, wait 60 seconds or back off. Create Mermaid Diagram allows 60 calls a minute\n5. Sharing and embed endpoints need an OAuth token. An API key won't work there\n\n### Mumble\n\n1. Don't plan to call Mumble from another agent. Neither the app nor `mumble-mcp` can be obtained publicly, so hand the task to a person with early access\n2. Don't configure `/path/to/mumble-mcp` from the docs. It is a placeholder, and no binary is published\n3. If the person already has Mumble, read ~/Mumble/\u003ccapture\u003e/ directly, `capture.json` for the transcript and `diagram.canvas` for the map\n4. Keep canvas keys in schema order and never rename a node id, or the edges that name it are orphaned and the canvas is refused. Use git as the undo\n5. Don't write to a capture that is being recorded. The app doesn't merge the two versions\n\n## Questions\n\n### Which is better for AI agents, Lucid API + MCP or Mumble?\n\nLucid API + MCP scores 60.6 (C) on agent readiness against Mumble's 7.5 (F), and leads in 6 of 7 scored categories. Mumble leads on payments \u0026 pricing.\n\n### Can an agent call Lucid API + MCP and Mumble without installing anything?\n\nLucid API + MCP has a hosted endpoint at https://api.lucid.co. No hosted endpoint is listed for Mumble.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/lucid-vs-mumble.json, and with the fewest tokens: https://www.anchorterminal.com/compare/lucid-vs-mumble.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"lucid\", \"b\": \"mumble\"}`.
