Why kg_get_project_state needs a policy

This is a read-only tool that retrieves project state data. It has no side effects, does not modify data, execute commands, delete resources, or commit financial obligations. The blast radius of misuse is minimal—an agent could access project information it shouldn't see, but cannot alter system state or trigger external operations.

From the tool's definition Tool name 'kg_get_project_state' and description 'Provides a comprehensive overview of a project' indicate a retrieval operation that queries and returns project state information without modification.

POLICY

How to control kg_get_project_state

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

policy.json

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

kg_get_project_state 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 Personal Kg — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
