Why batch_extract_from_repository needs a policy

The tool appears to extract code or documentation in batch from a repository and feed it into the Neo4j knowledge graph system. This is a read operation (retrieval/query).

From the tool's definition Tool name 'batch_extract_from_repository' suggests batch retrieval of code/data from a repository. The server context describes 'queryable knowledge graph' and 'code analysis' capabilities.

POLICY

How to control batch_extract_from_repository

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

policy.json

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

batch_extract_from_repository 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 Code Graph Knowledge System — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
