Verdicts
Lucid API + MCP
OAuth 2.0 scopes with :readonly variants, and audit log endpoints in the REST API. No public changelog for the API or the MCP server.
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.
Before you call either
Lucid API + MCP
- Always send
Lucid-Api-Version: 1, or prefix the path with /v1 - For flowcharts and sequence diagrams, post Mermaid markup (up to 100,000 characters) instead of building Standard Import JSON
- Request
:readonlyscopes when the agent only reads documents - On 429, wait 60 seconds or back off. Create Mermaid Diagram allows 60 calls a minute
- Sharing and embed endpoints need an OAuth token. An API key won't work there
Mural MCP
- Ask the person to open the target mural in a foreground browser tab, signed in to the connected account, before calling any tool
- Work on one mural at a time and name it explicitly when switching
- Request only murals:read when the task only reads a board
- Deletes go through without a server-side prompt. Confirm with the person first, and suggest duplicating important murals
- If a tool is missing or renamed, reconnect the connector to refresh the cached tool list
