Analyze a Python file for missing type annotations
AI agents call analyze_python_file to retrieve information from MCP Pyrefly Autotype Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and examines type annotation information from a Python file. It has no side effects—it does not execute code, modify files, delete data, or trigger external operations. It is a query/inspection operation that returns analysis results, fitting the Read category.
From the tool's definition Tool performs analysis to identify missing type annotations without modifying code. Description indicates it 'analyze[s]' and 'identify[ies]' issues rather than executing code or making changes.
Attacks that exploit this kind of access
Analyze a Python file for missing type annotations. It is categorised as a Read tool in the MCP Pyrefly Autotype Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Pyrefly Autotype Server MCP server in PolicyLayer and add a rule for analyze_python_file: 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 MCP Pyrefly Autotype Server. Nothing to install.
analyze_python_file is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the analyze_python_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.
Set action: deny in the PolicyLayer policy for analyze_python_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.
analyze_python_file is provided by the MCP Pyrefly Autotype Server MCP server (lolpack/mcp-pyrefly-autotype). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
