THE RISK

Low Risk

Why analyze needs a policy

The analyze tool retrieves and queries structural information about code duplicates using AST graph isomorphism analysis. It does not create, modify, delete, or execute any code. The operation is read-only and informational in nature, making it a Read category risk with low severity.

From the tool's definition Tool name is 'analyze' and description states 'Find duplicate code (verified via graph isomorphism)' — this is a search/detection operation with no side effects on the codebase.

POLICY

How to control analyze

PolicyLayer is an MCP gateway — it sits between your AI agents and Astrograph, and nothing reaches the server without passing your rules. This is the rule we recommend for analyze:

policy.json

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

analyze is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Astrograph — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about analyze

What does the analyze tool do? +

Find duplicate code (verified via graph isomorphism). It is categorised as a Read tool in the Astrograph MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on analyze? +

Register the Astrograph MCP server in PolicyLayer and add a rule for 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 Astrograph. Nothing to install.

What risk level is analyze? +

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

Can I rate-limit analyze? +

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

Set action: deny in the PolicyLayer policy for 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 analyze? +

analyze is provided by the Astrograph MCP server (thaylo/astrograph). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Astrograph tool call.

Start from Astrograph, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
