ctp_create_tool · CTP MCP Server MCP: Risk & Policy

WHAT IT DOES

What ctp_create_tool does on CTP MCP Server

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

WHY IT NEEDS A POLICY

Why ctp_create_tool needs a policy

This tool writes/creates new code artifacts including tool definitions, implementations, and tests. It is a Write operation because it produces new files/artifacts reversibly (they could be deleted). Severity is high because AI-generated production-ready code introduced into a codebase could have significant downstream effects if the generation is misused or produces malicious/incorrect code at scale.

From the tool's definition "Creates tool definition, implementation, and tests" — the tool generates and creates new artifacts (code files, tool definitions, test suites) from a natural language description

Verdict

ctp_create_tool Rate-limited

ctp_create_tool 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 ctp_create_tool

What does the ctp_create_tool tool do? +

Generate a complete CTP tool from a natural language description. Creates tool definition, implementation, and tests. It is categorised as a Write tool in the CTP 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 ctp_create_tool? +

Register the CTP MCP Server MCP server in PolicyLayer and add a rule for ctp_create_tool: 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 CTP MCP Server. Nothing to install.

What risk level is ctp_create_tool? +

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

Can I rate-limit ctp_create_tool? +

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

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

What MCP server provides ctp_create_tool? +

ctp_create_tool is provided by the CTP MCP Server MCP server (titan-alpha/ctp-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
