Claude Code - Happenstance

Add the Happenstance server:

claude mcp add --transport http happenstance https://happenstance.ai/mcp

Start Claude Code, run /mcp, select happenstance, and sign in to your Happenstance account in the browser window that opens.

To add it by hand instead, put this in .mcp.json in your project:

{
  "mcpServers": {
    "happenstance": {
      "type": "http",
      "url": "https://happenstance.ai/mcp"
    }
  }
}

Once connected, you can ask Claude Code things like:

“Who do we know that would make a great angel investor for us?”
“Who can introduce me to someone at Modal?”
“Find engineers in my YC group who have worked on distributed systems, and draft an intro request for the best three”
“Run a Happenstance research on Garry Tan, CEO of Y Combinator”
“Check my Happenstance credit balance”

People questions go to Happenstance Chat, which searches your network, explains who fits and who can introduce you, and drafts outreach. A reply usually takes 1 to 3 minutes.
