Hosted endpoint Claude Code Claude Desktop 75 tools

Option A — recommended

Hosted endpoint, nothing to install

For claude.ai web (OAuth sign-in), Claude Code, and any MCP client that speaks Streamable HTTP.

Get your API key

Log in to Mail-o-Mail → Settings → Home → API Access → Generate API Key. No account yet? The one-prompt setup lets Claude create one for you in conversation.

Add the server

In Claude Code, one command:

Terminal

claude mcp add --transport http mail-o-mail https://mail-o-mail.com/api/mcp --header "Authorization: Bearer YOUR_API_KEY"

Any other MCP client: point it at https://mail-o-mail.com/api/mcp (Streamable HTTP) and send your key as an Authorization: Bearer header.

Try it

Ask Claude: "Check my Mail-o-Mail account." It calls the whoami tool and reports your organization, credits, and WhatsApp status. Then: "Send a test email to me."

Using claude.ai in the browser? Go to Customize → Connectors and click Add, paste https://mail-o-mail.com/api/mcp, and claude.ai sends you to Mail-o-Mail to sign in and approve access (OAuth) — no API key needed. Signed in to the dashboard? The Talk page walks you through it step by step, with screenshots.

Option B

Claude Desktop — one file, five minutes

A small local MCP server that talks to our API. It can even create your account for you.

Download the server file

⬇ Download mcp_server.py

Then install its two dependencies: pip install mcp requests (Python 3.10+).

Add it to Claude Desktop

Edit claude_desktop_config.json — macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\ — and add:

claude_desktop_config.json

{ "mcpServers": { "mail-o-mail": { "command": "python", "args": ["/path/to/mcp_server.py"], "env": { "MOM_API_KEY": "YOUR_API_KEY" } } } }

Restart Claude Desktop

The Mail-o-Mail tools appear in Claude's tool menu. No API key yet? Leave MOM_API_KEY out and ask Claude to sign you up — the ai_signup and ai_verify tools create your account from the chat and hand you the key to paste in.
