Overview

AI-generated overview

Hosted SendGrid server that lets an assistant send email and read templates, marketing contacts, lists, delivery stats, bounces and unsubscribes.

What you can do
  • Send a real email immediately, with subject and content or a dynamic template
  • List and read transactional email templates, including their versions
  • List marketing lists, count contacts and look up contacts by exact email
  • Upsert marketing contacts and optionally add them to lists
  • Read global email stats over a date range, plus bounce and unsubscribe suppression lists
  • Check API key health and scopes, and manage usage, plan and feature requests
When to use it
Useful when you want an assistant to answer questions about SendGrid delivery, bounces and audience size, or to send transactional mail and update marketing contacts without leaving the chat.
Requirements
A remote MCP endpoint added by URL only; no package or local runtime. Sign-in is via OAuth, and the login page asks for a SendGrid API key, which is validated and stored per user. A free plan allows 50 tool calls per month; paid plans are billed separately.
Before you install
The server asks for a SendGrid API key during OAuth login; grant only the scopes you need. sendgrid_send_mail sends a real email immediately, and sendgrid_add_or_update_contacts changes marketing contacts as an async job, so confirm before running them. Paid plans involve payment links and subscriptions, and cancellation gives no refund for the current period.

Installation

In SourceWeft

  1. Open SendGrid MCP by usefulapi in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.usefulapi%2Fsendgrid/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Add this to your client's mcpServers config.

README

SendGrid MCP by usefulapi

Live endpoint: https://sendgrid.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://sendgrid.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http sendgrid https://sendgrid.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
json
{  "mcpServers": {    "sendgrid": {      "url": "https://sendgrid.usefulapi.io/mcp"    }  }}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your SendGrid credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/sendgrid/

On first connect you'll paste your SendGrid API key (SendGrid → Settings → API Keys). It's validated, stored per-user, and scoped to you — no keys in config files.
