WHAT IT DOES

What auto_callMcp does on Genesis

AI agents use auto_callMcp to create or update resources in Genesis, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Genesis environment.

Parameter	Type	Required	Description
`body`	object	Yes	One JSON-RPC 2.0 message. Omit `id` for a notification.

Parameters from the server's own tool schema.

RISK

Why auto_callMcp is rated Medium

An AI agent can call auto_callMcp faster than any human can review: one bad instruction and it creates or modifies resources in Genesis by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs auto_callMcp safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Genesis, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For auto_callMcp, this is the rule to start with:

auto_callMcp Rate-limited

auto_callMcp stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
