Available tools 1

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

email_send_message

Use this when you need to send an email to one or more recipients. Returns delivery confirmation in JSON. Returns: 1. messageId (unique identifier) 2. status (sent/queued/failed) 3. timestamp (ISO 8601) 4. to and from addresses 5. subject. Example output: {"messageId":"msg_01abc123","status":"sent","timestamp":"2026-04-13T14:30:00Z","to":"[email protected]","from":"[email protected]","subject":"Your Report"} Use this FOR sending transactional emails, notifications, alerts, password resets, order confirmations, and automated reports. Do NOT use for email validation -- use email_verify_address instead. Do NOT use for finding email addresses -- use email_find_by_name instead. Do NOT use for person data enrichment -- use person_enrich_from_email instead.

Email Send API — questions

Answers built from our own checks of this server.

What can Email Send API do?

It exposes 1 tools, read directly from the server on our last check. Among them: email_send_message. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Email Send API working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 46 ms. The bar chart above shows every period we have measured.

The registry lists Email Send API as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Email Send API?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Email Send API need an API key?

No. Email Send API completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.

Is Email Send API open source?

Yes — it is published under the MIT licence, written in TypeScript, 0 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
