Read lists, contacts, campaign stats; add contacts; draft, schedule and send campaigns and SMS. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
Turn on the Emailchef connector, then ask in plain words. The AI picks the tools.
For small teams that send email campaigns and SMS from an Emailchef account.
List your contact lists with the counts of active, unsubscribed and bounced contacts. Open one list to see its growth by day.
List the campaigns you sent. Read the links in one campaign and the engagement of its recipients to see who opened and clicked.
Create a contact from the details of a new lead and add it to your Newsletter list. Update the contact later when its details change.
Changes dataClone an existing draft campaign into a new draft. Read the timezones and the verified senders, then schedule the new draft for a day and time.
Changes dataRead the send limits and the credits left of the account. Check the SMS balance before you plan a text message to your customers.
The login page asks for your Consumer Key and Consumer Secret.
Create them in Emailchef → Settings → API Keys → Create API Key (only the account Owner can). The secret is shown once; if you lost it, delete the key and create a new one. Your keys are used only to call the Emailchef API on your behalf; they are never shown to anyone. Your Emailchef password is not needed.
Team and Enterprise: an Owner adds the connector for the organization first.
No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"emailchef": {
"url": "https://emailchef.usefulapi.io/mcp"
}
}
} Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"emailchef": {
"type": "http",
"url": "https://emailchef.usefulapi.io/mcp"
}
}
} Run these commands. The second one opens the login page:
Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.
Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Consumer Key and Consumer Secret. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper user | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+per user | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this Emailchef server only. Ask your AI to run emailchef_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with emailchef_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with emailchef_upgrade before then undoes the cancel. Or write to [email protected].

No. usefulapi is an independent service. It is not affiliated with or endorsed by Emailchef. The server calls the Emailchef API with your own Emailchef access, so it sees only the data that your account can see.
Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.
The login page asks for your Consumer Key and Consumer Secret. See Before you connect for where to find them.
No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Consumer Key and Consumer Secret. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Emailchef API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Emailchef.
Yes, if you approve it. 19 of the 43 Emailchef tools can create or change data. The other 24 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Emailchef server only. Cancel any time: your paid plan then runs to the end of the paid period. Run emailchef_usage_status to see how many calls you used.
Ask the AI to run emailchef_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run emailchef_cancel_subscription. Your paid plan continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with emailchef_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.
This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
