import_from_file · Code Context MCP: Risk & Policy

WHAT IT DOES

What import_from_file does on Code Context

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

WHY IT NEEDS A POLICY

Why import_from_file needs a policy

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

import_from_file Rate-limited

import_from_file 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.

Can I rate-limit import_from_file? +

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

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