create_pipeline · CATS MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_pipeline does on CATS MCP Server

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

WHY IT NEEDS A POLICY

Why create_pipeline needs a policy

Pipeline creation is a reversible write operation that modifies system state by adding a new pipeline configuration. The lack of description reduces confidence slightly, but the pattern of related tools (attach_*_tags, change_*_thumbnail, change_job_status) on the same ATS server confirms this is a write operation. No deletion, financial transaction, or code execution is implied.

From the tool's definition Tool name 'create_pipeline' indicates creation of a new pipeline entity. The context of a recruiting/ATS system suggests this creates a workflow pipeline for job tracking and candidate management.

Verdict

create_pipeline Rate-limited

create_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.

FAQ

Questions about create_pipeline

What does the create_pipeline tool do? +

create_pipeline. It is categorised as a Write tool in the CATS MCP Server 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_pipeline? +

What risk level is create_pipeline? +

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

Can I rate-limit create_pipeline? +

Yes. Add a rate_limit block to the create_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_pipeline completely? +

Set action: deny in the PolicyLayer policy for create_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.
