Overview

Description from the maker (original English)

Send email and read templates, marketing contacts, lists, stats, bounces and unsubscribes.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Before you install

  • Can do 11 things (tools) sendgrid_ping, sendgrid_list_templates, sendgrid_get_template, sendgrid_list_marketing_lists …
  • The registry lists no key to fill in.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

  • sendgrid_ping

    Health check — verifies the API key works and returns the scopes (permissions) granted to it. SendGrid: GET /v3/scopes.

  • sendgrid_list_templates

    List your transactional email templates (Dynamic and/or Legacy). Returns { result: [...], _metadata } — use _metadata.next / page_token to paginate. SendGrid: GET /v3/templates.

  • sendgrid_get_template

    Get a single transactional email template by id, including its versions (subject + content). SendGrid: GET /v3/templates/{template_id}.

  • sendgrid_list_marketing_lists

    List your Marketing Campaigns contact lists, each with its id, name, and contact_count. Returns { result: [...], _metadata }. SendGrid: GET /v3/marketing/lists.

  • sendgrid_get_contact_count

    Get the total number of Marketing Campaigns contacts on your account. Returns { contact_count, billable_count }. SendGrid: GET /v3/marketing/contacts/count.

  • sendgrid_search_contacts_by_email

    Look up marketing contacts by exact email address (a read-only lookup — mutates nothing). Returns { result: { " ": { contact: {...} } } }. SendGrid: POST /v3/marketing/contacts/search/emails.

  • sendgrid_get_stats

    Get global email statistics over a date range (delivered, opens, clicks, bounces, spam reports, etc.). Returns an array of { date, stats: [{ metrics: {...} }] }. SendGrid: GET /v3/stats.

  • sendgrid_list_bounces

    List bounced email addresses (the bounce suppression list). Returns an array of { created, email, reason, status }. SendGrid: GET /v3/suppression/bounces.

  • sendgrid_list_global_unsubscribes

    List globally-unsubscribed email addresses (the global suppression list). Returns an array of { created, email }. SendGrid: GET /v3/suppression/unsubscribes.

  • sendgrid_send_mail

    SENDS A REAL EMAIL immediately via SendGrid. Provide `from_email` and one or more `to` recipients, plus EITHER a subject + content OR a `template_id` (dynamic template ids start with "d-", pass values via dynamic_template_data). Returns { status: "accepted", message_id }. SendGri

  • sendgrid_add_or_update_contacts

    UPSERTS marketing contacts (creates new ones, updates existing ones by email) and optionally adds them to lists. This is an ASYNC job — returns { job_id } you can poll. SendGrid: PUT /v3/marketing/contacts.

Common questions

Is SendGrid MCP by usefulapi safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.35.3) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: MCP YouTube Transcript, Google Analytics MCP, BibiGPT YouTube Video Summarizer

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:
{

"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.
