transform_code · CodeCompass MCP: Risk & Policy

WHAT IT DOES

What transform_code does on CodeCompass MCP

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

WHY IT NEEDS A POLICY

Why transform_code needs a policy

The tool modifies code by applying transformations (syntax changes, structural reorganization, migrations). This is a Write operation as it creates or modifies data. While the description doesn't explicitly mention in-place file writes vs. returning transformed code as output, the word 'Apply' suggests actual modification rather than just suggesting changes.

From the tool's definition 'Apply code transformations including syntax changes, structural reorganization, framework migration, and modernization'

Verdict

transform_code Rate-limited

transform_code 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 transform_code

What does the transform_code tool do? +

🔧 Apply code transformations including syntax changes, structural reorganization, framework migration, and modernization. Combines syntax-level and structural changes. It is categorised as a Write tool in the CodeCompass MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on transform_code? +

Register the CodeCompass MCP server in PolicyLayer and add a rule for transform_code: 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 CodeCompass MCP. Nothing to install.

What risk level is transform_code? +

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

Can I rate-limit transform_code? +

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

Set action: deny in the PolicyLayer policy for transform_code. 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 transform_code? +

transform_code is provided by the CodeCompass MCP server (thealchemist6/codecompass-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
