Local-first MCP policy proxy. Tool-block, SQL-mutation gate, PII redact, audit, rate-limit, OpenTelemetry, vault secrets, first-use quarantine, schema pre-inject. No hosted gateway. One YAML Lens wraps any MCP, 20 included (Postgres, MySQL, MongoDB, GitHub, Stripe, Snowflake, etc.). 84% fewer tokens, ~3x faster, holds PII leaks. AGPL or commercial.

🚨

Secret credentials may flow to a network call

2 flows detected: VAULT_TOKEN, OP_SERVICE_ACCOUNT_TOKEN. We can’t prove the destination matches the brand the credential belongs to.

You'll be asked for 2 credentials: OP_SERVICE_ACCOUNT_TOKEN, VAULT_TOKEN

These are read from process.env at runtime. Make sure you trust where they’ll be sent.
