Tool changes

  • scan_mcp_serverchangeddescription, output schema
    before

    Scan a live MCP server's tool definitions for tool-poisoning, prompt-injection, invisible-unicode, and manifest-execution risks before your agent connects to it. Returns a 0-100 trust score, a safe / needs-review verdict, findings, and a signed attestation. Read-only; calls the agentavow.com public API.

    Scan a live MCP server's tool definitions for tool-poisoning, prompt-injection, invisible-unicode, and manifest-execution risks before your agent connects to it. Returns one of three answers with its reason (Safe to connect, Review before you connect, or Do not connect), a 0-100 trust score, findings, and a signed attestation. Read-only; calls the agentavow.com public API.

  • scan_packagechangeddescription, input schema, output schema
