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 .vscode/mcp.json:

{
  "servers": {
    "preflight": {
      "type": "http",
      "url": "https://preflight-api-production-01a2.up.railway.app/mcp"
    }
  }
}
For agents: the install prompt

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

# Install the MCP server PREFLIGHT — URL Routing for AI Agents (`io.github.GSterlingPress/preflight`)

Its page: https://plug.directory/servers/io.github.GSterlingPress/preflight

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

Use the section for the person's client.

## Claude Desktop

```text
https://preflight-api-production-01a2.up.railway.app/mcp
```

## Claude Code

Run in a terminal:

```sh
claude mcp add --transport http preflight https://preflight-api-production-01a2.up.railway.app/mcp
```

## Cursor, Devin Desktop, LM Studio, oterm, Bob Shell, ECA, Kiro, Kiro CLI

Merge into the place for the person's client:

- Cursor: ~/.cursor/mcp.json
