Warmly has an official hosted MCP server at https://opps-api.getwarmly.com/api/mcp. It uses OAuth (browser sign-in with Warmly account) over Streamable HTTP (remote; docs install with claude mcp add --transport http). Agents can use: list_warm_visitors (identified website visitors with company/contact profile, pages, UTM, CRM match), list_warm_accounts (visitors grouped by company), list_third_party_signals (by_signal discovery / by_company enrichment over ~395 signal subtypes).

Connect Warmly without code

Warmly's docs confirm it works in Claude. You don't need a terminal or a config file. Check Warmly's docs first: some vendors give you a personal URL or an API key to use in place of the plain endpoint.

Claude (web and desktop app)

If Warmly shows up when you browse connectors in Claude, connect it from there instead. That skips steps 2 to 4.

  1. In Claude, open Customize → Connectors.
  2. Click + Add, then Add custom connector.
  3. Name it “Warmly”, paste the server URL https://opps-api.getwarmly.com/api/mcp, and click Continue.
  4. Review the sign-in settings Claude detected and click Add.
  5. Click Connect and sign in to Warmly. Then ask Claude something like “What can the Warmly connector do?”

On Team and Enterprise plans, an Owner adds the connector first under Organization settings → Connectors → Add → Custom → Web. Each person then connects it from Customize → Connectors. Free plans can add one custom connector.

Steps from the Claude Help Center: support.claude.com, checked 2026-10-16
From Warmly's docs: Claude: add as a custom connector (Customize → Connectors → Add custom connector) with the endpoint URL; OAuth opens in a browser. Claude Code/Cursor: claude mcp add --transport http. Users in more than one Warmly org must append ?organization_id=<id> or send the X-Warmly-Organization-Id header, or they get 401 missing_org_context.Source: help.warmly.ai, checked 2026-10-16

Developer setup (Claude Code, Cursor)

Add this to .mcp.json (Claude Code, project root) or ~/.cursor/mcp.json (Cursor). Remove the // comment line if your client requires strict JSON.

{
  "mcpServers": {
    "warmly": {
      "url": "https://opps-api.getwarmly.com/api/mcp"
    }
  }
}
  1. Add the endpoint to your client config (above), or as a custom connector in Claude.
  2. Complete the OAuth sign-in. In Claude Code, run /mcp and pick the server.
  3. Test it with a prompt like: “List the tools the Warmly MCP server exposes.”
