What process_thoughts does on Project MCP

AI agents call process_thoughts to retrieve information from Project MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why process_thoughts needs a policy

This tool performs only retrieval operations: reading existing thought files and gathering contextual information from the project state. It has no side effects, does not modify or delete data, and does not execute external operations. The analysis responsibility is delegated to the LLM caller, not the tool itself. Classification as Read is appropriate.

From the tool's definition Tool description explicitly states it 'Reads brain dump markdown files' and 'returns the content along with project context' — pure data retrieval with no modification, creation, or deletion of resources.

How to control process_thoughts

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "process_thoughts": {}
  }
}

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

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