No public changelog for the API or the MCP server.\n\n**Mural MCP.** Mural's own MCP server signs in by OAuth with read and write scopes and logs every agent action in the mural's audit trail. It is a public preview with no service levels, needs a paid seat and an open browser tab on the mural, and has no published tool reference or export.\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### Mural MCP\n\n1. Ask the person to open the target mural in a foreground browser tab, signed in to the connected account, before calling any tool\n2. Work on one mural at a time and name it explicitly when switching\n3. Request only murals:read when the task only reads a board\n4. Deletes go through without a server-side prompt. Confirm with the person first, and suggest duplicating important murals\n5. If a tool is missing or renamed, reconnect the connector to refresh the cached tool list\n\n## Questions\n\n### Which is better for AI agents, Lucid API + MCP or Mural MCP?\n\nLucid API + MCP scores 60.9 (C) on agent readiness against Mural MCP's 42 (E), and leads in 5 of 7 scored categories. Mural MCP leads on maintenance \u0026 community.\n\n### Do Lucid API + MCP and Mural MCP need an API key?\n\nLucid API + MCP takes an API key or an OAuth sign-in. Mural MCP uses an OAuth sign-in.\n\n### Can an agent call Lucid API + MCP and Mural MCP without installing anything?\n\nYes. Lucid API + MCP has a hosted endpoint at https://api.lucid.co and Mural MCP at https://mcp-canvas.mural.co/mcp.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/lucid-vs-mural-mcp.json, and with the fewest tokens: https://www.anchorterminal.com/compare/lucid-vs-mural-mcp.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"lucid\", \"b\": \"mural-mcp\"}`.
