Invoke a specific AI agent with given inputs. The agent will execute within policy constraints and return structured output. All agent runs are logged for audit and traceability.

AI agents invoke invoke_agent to trigger processes or run actions in SendIt. 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.
invoke_agent 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 invoke_agent 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.
Invoke a specific AI agent with given inputs. The agent will execute within policy constraints and return structured output. All agent runs are logged for audit and traceability.. It is categorised as a Execute tool in the SendIt MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the SendIt MCP server in PolicyLayer and add a rule for invoke_agent: 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 SendIt. Nothing to install.
invoke_agent 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 invoke_agent 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 invoke_agent. 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.
invoke_agent is provided by the SendIt MCP server (https://sendit.infiniteappsai.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
