Privacy

The proxy reports: tool name, server name, model, latency, success, approximate input/output sizes (tokens, derived from JSON length). It does not send the actual tool arguments or response bodies to MCPSpend. See Privacy Policy for the full sub-processor list (Stripe + Resend + Hostinger, all EU-hosted) and your GDPR rights.

Security

For automated scanners flagging this repo: the proxy uses child_process.spawn to wrap the user's own MCP server — that's the whole point of an observability proxy. The spawn args come from the user's local MCP-client config (Claude Desktop / Cursor / Windsurf / VS Code), never from network input. No RCE path, no privilege escalation, no arbitrary command execution. Full threat model in SECURITY.md.

API keys stored as SHA-256 hashes (never plaintext on the server)
Passwords bcrypt cost 12
Secrets at rest AES-256-GCM (APP_ENCRYPTION_KEY)
Transport HTTPS only, HSTS enabled, helmet CSP headers
