lowkeyvc-mcp

An MCP server that gives an AI agent live access to LowkeyVC — the VC deal-flow signal engine. It surfaces the two datapoints LowkeyVC is built around:

• The signal — a tracked VC just followed a startup.
• Convergence — how many tracked VCs have piled onto the same startup.

The server is a thin, read-only wrapper over the hosted LowkeyVC REST API. Every figure it returns matches the public feed and is reproducible from the archive.

Install

You need a LowkeyVC API key (a lk_... token). Ask your LowkeyVC operator to issue one.

Claude Code

claude mcp add lowkeyvc --env LOWKEYVC_API_KEY=lk_your_key -- npx -y lowkeyvc-mcp

Claude Desktop / other MCP clients

Add to your client's MCP config (for Claude Desktop, claude_desktop_config.json):

{
  "mcpServers": {
    "lowkeyvc": {
      "command": "npx",
      "args": ["-y", "lowkeyvc-mcp"],
      "env": {
        "LOWKEYVC_API_KEY": "lk_your_key"
      }
    }
  }
}

Restart the client. The lowkeyvc tools become available immediately — no other setup, no local checkout.

Configuration

| Env var | Required | Default | Notes | |---------|----------|---------|-------| | LOWKEYVC_API_KEY | yes | — | Your lk_... bearer token. | | LOWKEYVC_API_URL | no | https://lowkey-vc-e8b26fb6d2c3.herokuapp.com | Override to point at staging, a custom API domain, or a self-hosted instance. |

Tools

| Tool | What it does | |------|--------------| | list_signals | Net-new VC→startup follows, cursor-paginated (omit since for the head, then pass back next_cursor). | | list_startups | The convergence leaderboard, ranked by how many tracked VCs converged in-window. founders: true filters to deal flow. | | get_startup | One startup's detail by X username. | | list_investors | The tracked-VC roster, ordered by in-window activity. | | get_investor | One investor's profile plus their recent in-window follows. |

Convergence terms: observed_investors are VCs watched following in the window (the strong signal); inferred_investors predate tracking (context, kept separate); total_investors is their sum.

Development

npm install
npm test          # unit + in-memory integration tests
npm run build     # compile to dist/
npm run smoke     # live check against the API (needs a real LOWKEYVC_API_KEY)
