What we checked

Security

  • Passed: Connections are encrypted (HTTPS).

  • Passed: No hidden instructions found in tool text.

Safety labels

  • Note: 1 tool is labelled as able to change things.

    Expected for tools that send, write or buy. Your AI client should ask before calling them.

    • run_bellhop_volume
  • Passed: Every tool says whether it only reads or can change things.

Tools

  • Passed: 13 tools listed.

  • Passed: Every tool describes its inputs with a valid schema.

Protocol

  • Passed: The MCP handshake works (Streamable HTTP).

  • Passed: Protocol version 2025-11-25 (latest).
