About
CHP Profile B spend/HITL gate: evaluate_spend_gate, approve_spend, content hash.
Security Report
This is a well-structured MCP server that wraps a cryptographic spend-gate library with proper input validation via Zod schemas and clean error handling. No authentication is required (appropriate for a policy evaluation library), permissions are minimal and match the server's purpose, and there are no malicious patterns or credential handling issues. Minor code quality observations around broad exception handling do not meaningfully impact security. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.

@cubiczan/chp-mcp
One-command MCP install for CHP Profile B spend / capital gates.
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).
