Send email from Claude

To send email from Claude, add AgentiSend in Claude's connector directory, sign in, and ask Claude to send. The same connection works on claude.ai and in the desktop app.

To send email from Claude, add AgentiSend as a connector, sign in, and ask Claude to send. Claude then calls the same API your own code calls. The ceiling is checked before the message is accepted, and a refusal comes back with a fix. The same steps work on claude.ai and in the desktop app.

Connect it

Open https://claude.ai/directory/agentisend and click Connect. If the listing does not open, add a custom connector in Customize, Connectors, and paste https://api.agentisend.com/mcp. Sign in to AgentiSend and approve. Claude holds the connection. There is no key to copy on this path.

A connection is listed by GET /oauth/grants. A signed-in person ends it with DELETE /oauth/grants/{id}. It starts with the budget every new key gets. A person lowers it with PATCH /limits/keys/{id}. The key cannot raise that ceiling.

Ask Claude to send a short note from onboarding@agentisend.com to your sign-in address. That sender delivers only to member sign-in addresses. An address at simulator.agentisend.com costs nothing and reaches nobody. POST /emails is the call Claude makes.

The two longer pages

Send email from Claude Desktop has the local launcher, for a config file that runs programs on the computer. A remote URL in that file does nothing. Send email from Claude Code has the CLI install. This page is the connector, which is the path that needs no pasted key.

Claude — claude_desktop_config.json

To run AgentiSend on this computer instead, paste this into Claude Desktop’s claude_desktop_config.json and restart the app (it needs Node.js). That file only runs local servers, so it starts ours with npx. To connect without a key, use Customize → Connectors in Claude.
