TruthGate MCP runs 100% locally to protect developers and teams from the three biggest hazards in autonomous coding agents (Claude Code, Cursor, Codex, OpenClaw):

  1. Accidental Credential & PII Leakage: Scans and masks .env secrets, AWS keys, API keys, and customer data in < 2ms before context leaves your machine.

  2. "Silent Fake Success": Stops AI agents from claiming bugs are fixed by tampering with test assertions, commenting out test cases, or injecting bogus mocks.

  3. Destructive Command Airbag: Intercepts rm -rf, DROP TABLE, and forced git overwrites.


⚡ 1-Minute Quickstart

Option 1: Run with Claude Desktop / Claude Code CLI

      "command": "npx",
      "args": ["-y", "github:wu00112238/truthgate-mcp"]
    }
  }
}

Option 2: Run in Cursor MCP Settings

    B3.4/5.0

    Scored across 4 tools

    Disambiguation4/5

    The three functional guardrail tools have clearly distinct purposes: masking sensitive context, checking test integrity, and inspecting actions. The upgrade_pro_credits tool is also clearly different, but it is a commercial action rather than a guardrail operation, which slightly reduces set-level coherence.

    Naming Consistency5/5

    All tool names use the same truthgate_ prefix and consistent snake_case verb_noun structure. The pattern is predictable across all four tools.

    Tool Count4/5

    Four tools is a reasonable size for a focused guardrail server, and the three core safety tools are well-scoped. However, one slot is occupied by a Pro credit purchase tool rather than a functional operational capability.

    Completeness3/5

    The server covers three important safety checks, but it lacks tools for configuring policies, retrieving audit logs, or checking license/audit status. The upgrade tool references audit logs and priority guardrails without exposing corresponding operational tools.
