Claude Code, Cursor and other clients

claude mcp add --transport http havincy https://havincy.com/mcp

Then type /mcp in Claude Code, select havincy and sign in. Generated files come back as links your agent can download into your project.

Open Cursor Settings → MCP → Add new MCP server, or edit ~/.cursor/mcp.json:

{
  "mcpServers": {
    "havincy": { "url": "https://havincy.com/mcp" }
  }
}

Cursor opens the Havincy sign-in the first time a tool is used.

Clients that do not support OAuth can send an API key:

{
  "mcpServers": {
    "havincy": {
      "url": "https://havincy.com/mcp",
      "headers": { "Authorization": "Bearer hv_live_..." }
    }
  }
}

Test with MCP Inspector

npx @modelcontextprotocol/inspector

Choose Streamable HTTP, enter https://havincy.com/mcp and connect: the inspector runs the OAuth flow, then lists the tools.
