What is the Haruspex Skills MCP server?

The server reads HARUSPEX_API_KEY at runtime for live data; get a key at https://haruspex.guru/settings. The Anthropic Skills below depend on this MCP server for their data — without it installed, the skills detect that, output install. Exposed over MCP by the haruspex skills mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

Adding it to your client

@haruspex-guru/mcp-server on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Configuration

You will need one environment variable: HARUSPEX_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

  • A Haruspex API key — sign up at https://haruspex.guru. Never commit your API key to a repository. - One of: Claude Code, Claude.ai web, or the Claude API. - Node.js 18+ if you're running @haruspex-guru/mcp-server via npx. Full per-surface MCP setup details live in shared/MCP_SETUP.md.

When to reach for it

Plenty of AI and media services servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. It is maintained by haruspex-guru; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Caveats

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the haruspex skills mcp server does with a few real requests.
