create_relay_pipeline · Agent Runtime MCP: Risk & Policy

WHAT IT DOES

What create_relay_pipeline does on Agent Runtime

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

WHY IT NEEDS A POLICY

Why create_relay_pipeline needs a policy

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

create_relay_pipeline Rate-limited

create_relay_pipeline 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Agent Runtime, so you can run agents against it safely.

FAQ

Questions about create_relay_pipeline

What does the create_relay_pipeline tool do? +

create_relay_pipeline. It is categorised as a Write tool in the Agent Runtime MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_relay_pipeline? +

Register the Agent Runtime MCP server in PolicyLayer and add a rule for create_relay_pipeline: 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 Agent Runtime. Nothing to install.

What risk level is create_relay_pipeline? +

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

Can I rate-limit create_relay_pipeline? +

Yes. Add a rate_limit block to the create_relay_pipeline 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 create_relay_pipeline completely? +

Set action: deny in the PolicyLayer policy for create_relay_pipeline. 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.
