What it does

ActionGuard Protocol Inspector Agent is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.

No capability identified yet from its description.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence) and are not a test of the tool.

2 tools offered to AI assistants

  • actionguard_inspect · Run a 5-stage continuous reliability, security, and schema audit of an MCP server or AI agent endpoint.
  • actionguard_check_drift · Verify whether an MCP server's tools schema or descriptions have drifted from a pinned Dual-Hash.

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
