Measure cyclomatic complexity and suggest refactoring opportunities
AI agents call complexity_analyzer to retrieve information from My First MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool analyzes code to measure complexity metrics and provide suggestions. It reads/analyzes existing code without modifying, executing, or deleting anything. The output is informational (complexity scores and refactoring suggestions), making this a pure read/analysis operation.

Attacks that exploit this kind of access
Measure cyclomatic complexity and suggest refactoring opportunities. It is categorised as a Read tool in the My First MCP Server MCP Server, which means it retrieves data without modifying state.
Register the My First MCP Server MCP server in PolicyLayer and add a rule for complexity_analyzer: 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 My First MCP Server. Nothing to install.
complexity_analyzer 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 complexity_analyzer 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 complexity_analyzer. 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.
complexity_analyzer is provided by the My First MCP Server MCP server (sethdavis512/my-first-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
complexity_analyzer is one line of My First MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
