Warmerly MCP server

Warmerly MCP server

Connect any AI assistant to your Warmerly workspace. Website · Docs · Claude Code plugin

https://app.warmerly.com/api/mcp

A remote Model Context Protocol server (streamable HTTP, OAuth 2.1). Sign in with your normal Warmerly account and choose one workspace; the connection can only see and act in that workspace. Every Warmerly plan can connect, including Free. No API key needed.

This repo holds copy-paste setup for each client. The server itself is hosted by Warmerly and listed in the official MCP Registry as com.warmerly/warmerly (server.json here).

What you can ask

• "Find UK marketing agencies with 10–50 staff and build a two-step campaign for them."
• "Which of my mailboxes are unhealthy, and why?"
• "Check SPF, DKIM, DMARC and MX for acme.com and tell me what to fix."
• "Show me replies that need an answer and draft a response to each."
• "Pause every campaign that's bouncing above 3%."
• "Verify jane@acme.com."

Setup

ChatGPT

Search for Warmerly in the ChatGPT plugin directory. Until it's listed, turn on developer mode (Plus, Pro, Business, Enterprise or Edu), then Plugins → Add → Create MCP App with the URL above and OAuth authentication.

Claude (claude.ai and the desktop app)

Settings → Connectors → Add custom connector, paste the URL above, then Connect and sign in. On Team and Enterprise plans an owner adds it under Organization settings → Connectors.

Claude Code

Install the plugin (server plus four workflow skills):

/plugin marketplace add WarmerlyApp/claude-plugin
/plugin install warmerly@warmerly

Or add just the server:

claude mcp add --transport http warmerly https://app.warmerly.com/api/mcp

Then run /mcp and sign in.

Cursor

~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project):

{
  "mcpServers": {
    "warmerly": { "url": "https://app.warmerly.com/api/mcp" }
  }
}

Open Settings → MCP and sign in when prompted.

VS Code (GitHub Copilot agent mode)

Run MCP: Add Server, or put this in .vscode/mcp.json (or MCP: Open User Configuration for every workspace):

{
  "servers": {
    "warmerly": { "type": "http", "url": "https://app.warmerly.com/api/mcp" }
  }
}

A browser window opens to sign in the first time a tool is used.

Windsurf

mcpconfig.json (~/.codeium/windsurf/mcpconfig.json on most installs; open it from the MCP settings panel to be sure):

{
  "mcpServers": {
    "warmerly": { "serverUrl": "https://app.warmerly.com/api/mcp" }
  }
}
