broker_mutate

MCP tool from Credential Broker MCP by SarutobiSasuke8

POST, PUT, PATCH, or DELETE. Annotated destructive and non-idempotent, because its strongest capability is. May require an approval and an idempotency key.

How to use it

Project documentation lists broker_mutate for the Credential Broker MCP MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.
