# jamjet-policy

> Use this tool when you need to control and manage access to MCP tools and call requests. The jamjet-policy tool acts as a stdio interceptor, allowing you to set policies via YAML to block, require approval, audit, or enforce budget caps on requests. It provides a unified rule set for various clients, including Claude Desktop, Cursor, OpenAI Agents, and custom clients.

## Description

Drop-in stdio interceptor that gates MCP tools/call requests through a YAML policy (block / require_approval / audit / budget cap) before they reach the real server. The same policy file is reused by @jamjet/claude-code-hook and @jamjet/openai-guardrail, so one rule set covers Claude Desktop, Cursor, OpenAI Agents, and custom clients.
