Verdicts
Cloudviz API
Diagrams come from the live AWS account through a read-only cross-account role with a per-customer external ID. AWS only, and API access starts at the $49 a month Team plan.
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
Cloudviz API
- Call
GET /aws/accounts/first to get the Cloudviz account ID, then request/aws/accounts/{account-id}/{region}/{format} - On a 202, wait and repeat the same GET until the diagram is ready
- Ask for
jsonSnapshotorjsonDiagram(there is no plainjsonformat) when the agent has to reason over resources - Use a read-only key unless the agent has to add, change or delete AWS accounts
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
