Install SecureSMTP MCP server
The server’s own address, for the clients that take one directly. Or connect ahel onceand every client you use reads it from one address, with the account kept on ahel rather than in each client’s config.
Claude Code
claude mcp add --transport http --scope user securesmtp-mcp-server 'https://securessmtp.com/api/mcp'Run it once in your project, then open /mcp to approve any sign-in the server asks for.
Claude Desktop
https://securessmtp.com/api/mcpAdd a custom connector in Settings, paste this address, and approve the sign-in.
Cursor

From the project's README
As published by zainsaeed615/securessmtp-mcp in README.md.
Connect SecureSMTP to Claude and other MCP clients. Send transactional mail, manage sending domains, and read delivery analytics for your account — in natural language.
- Endpoint:
https://securessmtp.com/api/mcp(Streamable HTTP) - Auth: OAuth 2.1 (one-click, recommended) or a site API key as a Bearer token
- Cost: free — every call runs against your own account and stays within your plan limits
What it can do
| Tool | What it does |
|---|---|
get_account | Plan tier, email quota (used / limit / remaining), number of sending domains |
list_sending_domains | List the account's sending domains and their verification status |
add_sending_domain | Add a sending domain; returns the DNS records to publish |
verify_domain | Verify a sending domain's DNS (SPF / DKIM) |
get_deliverability | Delivery status counts for the last 30 days (delivered / opened / bounced / …) |
send_email | Send a transactional email — enforces the same quota, spam scoring, and suppression as the API |
Every tool is scoped to a single site, so a connection can only ever see or act on that account.
Connect from Claude Code
OAuth (opens a browser to approve):
claude mcp add --transport http securessmtp https://securessmtp.com/api/mcp
Or with a site API key (no browser step):
claude mcp add --transport http securessmtp https://securessmtp.com/api/mcp \
--header "Authorization: Bearer <your-site-api-key>"
Connect from claude.ai (custom connector)
Requires a claude.ai Pro/Team/Enterprise plan (custom connectors are not available on the free tier).
- Settings → Connectors → Add custom connector
- URL:
https://securessmtp.com/api/mcp - Approve access when the SecureSMTP consent screen appears, and pick which site to grant.
Where to get an API key
Sign in at securessmtp.com, open a site, and copy its API key — the same key the WordPress plugin and REST API use.
How auth works
- OAuth 2.1 with PKCE and dynamic client registration. Discovery lives at
/.well-known/oauth-protected-resourceand/.well-known/oauth-authorization-server. Access tokens are short-lived; refresh tokens rotate. - API key — send the site key as
Authorization: Bearer <key>.
