WHAT IT DOES

What complexity_analyze does on Plugin Hub

AI agents call complexity_analyze to retrieve information from Plugin Hub without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why complexity_analyze is rated Low

Even though complexity_analyze only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs complexity_analyze safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Plugin Hub, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For complexity_analyze, this is the rule to start with:

complexity_analyze Allowed

complexity_analyze is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "complexity_analyze": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Plugin Hub, apply this rule, and every complexity_analyze call is checked against it from then on.

FAQ

Questions about complexity_analyze

What does the complexity_analyze tool do? +

Analyze cyclomatic complexity of functions and identify overly complex code. It is categorised as a Read tool in the Plugin Hub MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on complexity_analyze? +

Register the Plugin Hub MCP server in PolicyLayer and add a rule for complexity_analyze: 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 Plugin Hub. Nothing to install.

What risk level is complexity_analyze? +

complexity_analyze is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit complexity_analyze? +

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

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

complexity_analyze is provided by the Plugin Hub MCP server (@barnburner121/plugin-hub-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
