icohangar-ops/cubiczan-chp-mcp MCP server

One-command MCP install for CHP Profile B spend / capital gates.

MCP Registry npm Conformance

Wraps @cubiczan/chp so Cursor, Claude Code, or any MCP client can call evaluate_spend_gate without vendoring protocol code. Engine digests match the normative golden vectors (Profile B 30/30).

How the pieces fit
