AI agents invoke gossip_run to trigger processes or run actions in Gossipcat. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
gossip_run can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

These attack patterns abuse exactly the kind of access gossip_run gives an agent. Each links to the full case and the policy that stops it:
Other execute tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Run a task on a single agent and return the result. For relay agents (Gemini), this is a single call — dispatches, waits, returns. For native agents (Sonnet/Haiku), returns dispatch instructions with gossip_relay callback. Use agent_id:"auto" to let the orchestrator decompose and assign agents automatically.. It is categorised as a Execute tool in the Gossipcat MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Gossipcat MCP server in PolicyLayer and add a rule for gossip_run: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Gossipcat. Nothing to install.
gossip_run is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the gossip_run 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.
Set action: deny in the PolicyLayer policy for gossip_run. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
gossip_run is provided by the Gossipcat MCP server (gossipcat). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
