Connect Enginemailer to Claude, ChatGPT or Cursor

Connect Enginemailer in Corsair
Add your Enginemailer API key once in Corsair. Corsair stores the credential encrypted and makes the Enginemailer API calls for your agent, so it never goes into a prompt or a config file. Connect Enginemailer
If your link lets the agent add apps, you can skip this: it gives you a sign-in link the first time it needs Enginemailer. On a ChatGPT personal plan, connect Enginemailer here first.

Add Corsair's MCP server to your agent
Every client uses the same address:
https://mcp.corsair.dev/mcpOpen Customize → Connectors → Add custom connector, paste the address, then select Connect.Add a custom MCP server with the address and choose OAuth. Personal plans get read tools only.Add to CursorOr add this to~/.cursor/mcp.json. Cursor opens Corsair to sign in the first time it connects.{ "mcpServers": { "corsair": { "url": "https://mcp.corsair.dev/mcp" } } }Run this, then run/mcpin Claude Code to sign in.claude mcp add --transport http corsair https://mcp.corsair.dev/mcpCodex, Gemini CLI, VS Code, Zed and other clients with OAuth sign-in work the same way. Clients without it, such as GitHub Copilot's coding agent, use a link's own address and an API key. Setup for every client

Sign in and choose what needs your approval
Your client opens Corsair to sign in. Pick a link: the apps your agent can use and a mode that decides what it may do without asking. In the default Cautious mode, Enginemailer's read and write operations run right away and its 7 destructive operations wait for your approval. Strict mode asks before every write and refuses destructive operations, and Read mode allows reads only.
FAQ
Install corsair and @corsair-dev/enginemailer, add the Enginemailer plugin, and connect with an API key. Then call methods like corsair.enginemailer.api.campaigns.assignRecipientList() from your app. Corsair keeps each tenant isolated.
Yes. Enginemailer requires an API key from your Enginemailer account or developer dashboard. Create credentials with access that matches what you automate, then paste them into Corsair or connect through managed auth in Hub.
Yes. One Corsair client can hit Enginemailer, GitHub, Notion, Stripe, and the rest. Trigger Enginemailer from a webhook, push updates to Slack, or chain actions across plugins. Same tenant context across integrations, plain TypeScript.
Teams use Corsair for manage enginemailer subscribers, categories and custom fields, build and send email campaigns, and read subscriber activity through enginemailer's n8n api. Common builds include sync jobs, admin tooling, and agents that call Enginemailer APIs from your backend.
The SDK is open source. Self-host and you pay Corsair nothing for the integration layer. Hub bills for hosted auth and execution, not per Enginemailer API call. Hub has a generous free tier. For hobby projects you can probably run the whole thing on free. Paid plans start to matter with more tenants or heavier traffic.
We maintain @corsair-dev/enginemailer in the open repo. When Enginemailer ships API changes, upgrade the package. Your call sites stay typed. You should not need to rewrite the integration layer each time.
No. Corsair does not read your Enginemailer data or hold individual access credentials. Credentials stay in your database. API calls run on your instance. We do not store Enginemailer data on your behalf.
Yes. Add https://mcp.corsair.dev/mcp as a custom connector or MCP server in Claude, ChatGPT, Cursor, VS Code, Claude Code, Codex or any client that supports remote MCP servers with OAuth sign-in, then sign in to Corsair. On ChatGPT personal plans, custom servers currently get read tools only.
Yes. Put Enginemailer on a link in Strict mode and every write waits for your approval, while destructive actions are refused. The default Cautious mode asks only before the 7 destructive Enginemailer operations. You can change a link's mode at hub.corsair.dev/me.
