# 04 — MCP-shaped tool policy (preview)

Show JamJet evaluating policy against an MCP-shaped tool request. This is a
**preview** of the upcoming JamJet Gateway, which will run as an MCP proxy
between Claude Desktop / Cursor / any MCP client and the real MCP servers.

Today the demo evaluates the policy synchronously. The Gateway will run as a
standalone process and apply the same policy across networked MCP traffic.
