01 · Install Railhook

Claude Code

claude mcp add vadymkykalo-railhook --transport http https://railhook.io/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "vadymkykalo-railhook": {
      "url": "https://railhook.io/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions · remote - your agent's requests go to railhook.io

endpoint auth requires authentication - rejected our unauthenticated MCP initialize

license MIT - declared in the repository

npm package @railhook/mcp - the @railhook scope differs from the repo owner (vadymkykalo); confirm it's the project's official package

registry namespace io.github.vadymkykalo is GitHub-verified and matches the repo owner

03 · What Railhook can do

Prose above is summarized from the project's README and registry record - no invented capabilities.
