WHAT IT DOES

What evidence_export does on Jshookmcp

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

RISK

Why evidence_export is rated Medium

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

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs evidence_export safely

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

evidence_export Rate-limited

evidence_export 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Jshookmcp, apply this rule, and every evidence_export call is checked against it from then on.

What risk level is evidence_export? +

evidence_export is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit evidence_export? +

Yes. Add a rate_limit block to the evidence_export rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block evidence_export completely? +
