[ 01 / 06 ]Connect

How do I connect to the Send & Retain MCP server?

One command in Claude Code, then a browser sign-in. Other clients take the same URL.

  1. Add the server

    In Claude Code, run this in your terminal. No API key, no config file.

    Terminal
    claude mcp add --transport http sendandretain https://sendandretain.com/api/mcp

  2. Using another client? Use the URL

    Cursor, Codex, Gemini CLI, and VS Code take it in their MCP config. Claude adds it as a custom connector under Customize → Connectors, and ChatGPT as a developer-mode app.

    MCP server URL
    https://sendandretain.com/api/mcp

  3. Sign in through the browser

    The server uses OAuth 2.1, so your client opens a sign-in page. Approve once and it keeps the token.

  4. Check it works

    Ask: "List my Send & Retain projects." You should see your projects, or an offer to create one.

[ 02 / 06 ]Tools

What tools does the email MCP server have?

Every dashboard action is a tool, on the same core as the REST API.

Templates

Write react.email templates, render them, test them, and publish.

email_create_template · email_render_template · email_publish_template_version

Automations

Build automations from product events. They're created paused.

email_create_automation · email_preview_automation · email_set_automation_status

Contacts and events

Add contacts, record events, and build segments.

email_upsert_contact · email_emit_contact_event · email_create_segment

Sending

Send one transactional email or a test, through the same checks as the API.

Metrics

Delivery, engagement, and trends by automation and template.

email_get_email_metrics · email_get_automation_metrics · email_get_metrics_trends

[ 03 / 06 ]Example prompts

What can you ask once it's connected?

Start read-only, then hand it a real change.

  • Audit

    “Check my sending setup and tell me what's misconfigured. Don't change anything.”

  • Domain

    “Set up sending for acme.com and give me the DNS records to add.”

  • Automation

    “Build a paused trial conversion automation that stops when subscription_started arrives.”

  • Diagnose

    “Why did this contact not get our welcome email? Check suppressions and the message log.”

[ 04 / 06 ]Access

Is it safe to give an agent email tools?

Yes. The sign-in says who is acting and what they can reach, and the risky checks sit on the action itself, not on the client that asked.

  • Browser sign-in acts as you, and is checked again on every call.
  • Unattended agents use a scoped API key, pinned to one project, that never auto-applies a change.
  • Revoking a key stops REST and MCP together. There's no second credential to forget.
  • Provider keys never travel over MCP. You paste them into the dashboard yourself.
  • Automations are created paused, and turning one on needs your confirmation.
