Check type annotations with mypy. NOTE: this tool is slow (10-30s) on first run.
AI agents call analyze_types to retrieve information from Code Quality without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and analyzes Python code to report type annotation issues. It is deterministic static analysis that produces informational output about code quality. While slow on first run, it has no destructive, write, execute, or financial impact. It falls squarely into the Read category as a query/analysis function that retrieves linting results.
From the tool's definition Tool performs static type checking analysis using mypy, which 'Check[s] type annotations' without modifying code or executing runtime operations.
Attacks that exploit this kind of access
Check type annotations with mypy. NOTE: this tool is slow (10-30s) on first run. It is categorised as a Read tool in the Code Quality MCP Server, which means it retrieves data without modifying state.
Register the Code Quality MCP server in PolicyLayer and add a rule for analyze_types: 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 Code Quality. Nothing to install.
analyze_types 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_types 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_types. 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_types is provided by the Code Quality MCP server (javier-morenosa/code-quality-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
