A failure counts as down time only when a second check five minutes later fails too. How we check

Connect to the publisher's own endpoint

Add to anythingllm_mcp_servers.json in the AnythingLLM storage plugins directory:

{
  "mcpServers": {
    "402shield": {
      "type": "streamable",
      "url": "https://four02shield.onrender.com/mcp"
    }
  }
}
For agents: the install prompt

Every step above as one Markdown text, for an assistant installing it for you.

# Install the MCP server `io.github.MitchSingh/402shield`

Its page: https://plug.directory/servers/io.github.MitchSingh/402shield

It runs on the publisher's servers; the client connects to its URL.

Use the section for the person's client.
