Which API key permissions does it need?

Mail Send + Stats Read for the default tool set. Add Suppressions Read/Write to manage the bounce list. Never give the agent the Full Access key.

Does it support subusers?

Yes via the on-behalf-of header. Pass SENDGRID_SUBUSER to scope all calls to one subuser without rotating keys.

Activity Feed search granularity?

Per-recipient, per-status, per-time-window. The Activity Feed v3 endpoint is what the SendGrid UI itself uses — same fidelity for the agent.

Quick answer

What it does

Wraps the SendGrid v3 REST API: send mail, query Activity Feed, list suppressions, inspect authenticated senders and IPs.

Best for

Transactional send
Activity Feed investigation
Suppression list audits
Sender auth verification

Not for

High-volume marketing campaigns from chat
Workflows that need granular IP pool selection from the model

Setup recipe

Pick your client, then follow the three steps.

Install

claude_desktop_config.jsonjson

{
  "mcpServers": {
    "sendgrid": {
      "command": "npx",
      "args": [
        "-y",
        "sendgrid-mcp"
      ],
      "env": {
        "SENDGRID_API_KEY": "${SENDGRID_API_KEY}",
        "SENDGRID_FROM": "${SENDGRID_FROM}"
      }
    }
  }
}

Paste under mcpServers. Fully quit and reopen Claude after editing.

CLI or .mcp.jsonshell

# export SENDGRID_API_KEY=SG.changeme
# export SENDGRID_FROM=agent@example.com
claude mcp add sendgrid -- npx -y sendgrid-mcp

Run from your repo. Commit .mcp.json to share with your team.

.cursor/mcp.jsonjson

{
  "mcpServers": {
    "sendgrid": {
      "command": "npx",
      "args": [
        "-y",
        "sendgrid-mcp"
      ],
      "env": {
        "SENDGRID_API_KEY": "${SENDGRID_API_KEY}",
        "SENDGRID_FROM": "${SENDGRID_FROM}"
      }
    }
  }
}

Global path: ~/.cursor/mcp.json. Reload window after editing.

.vscode/mcp.jsonjsonc

{
  "servers": {
    "sendgrid": {
      "command": "npx",
      "args": [
        "-y",
        "sendgrid-mcp"
      ],
      "env": {
        "SENDGRID_API_KEY": "${SENDGRID_API_KEY}",
        "SENDGRID_FROM": "${SENDGRID_FROM}"
      }
    }
  }
}

VS Code uses the "servers" key (not "mcpServers").

~/.codeium/windsurf/mcp_config.jsonjson

{
  "mcpServers": {
    "sendgrid": {
      "command": "npx",
      "args": [
        "-y",
        "sendgrid-mcp"
      ],
      "env": {
        "SENDGRID_API_KEY": "${SENDGRID_API_KEY}",
        "SENDGRID_FROM": "${SENDGRID_FROM}"
      }
    }
  }
}

Open via Cascade → hammer icon → Configure.

cline_mcp_settings.jsonjson

{
  "mcpServers": {
    "sendgrid": {
      "command": "npx",
      "args": [
        "-y",
        "sendgrid-mcp"
      ],
      "env": {
        "SENDGRID_API_KEY": "${SENDGRID_API_KEY}",
        "SENDGRID_FROM": "${SENDGRID_FROM}"
      }
    }
  }
}

Open via the Cline sidebar → MCP Servers → Edit.

~/.continue/config.jsonjson

{
  "experimental": {
    "modelContextProtocolServers": [
      {
        "transport": {
          "type": "stdio",
          "command": "npx",
          "args": [
            "-y",
            "sendgrid-mcp"
          ],
          "env": {
            "SENDGRID_API_KEY": "${SENDGRID_API_KEY}",
            "SENDGRID_FROM": "${SENDGRID_FROM}"
          }
        }
      }
    ]
  }
}

Continue uses modelContextProtocolServers with a transport block.

~/.codex/config.tomlshell

# ~/.codex/config.toml
[mcp_servers.sendgrid]
command = "npx"
args = [
  "-y",
  "sendgrid-mcp",
]
env = { SENDGRID_API_KEY = "${SENDGRID_API_KEY}", SENDGRID_FROM = "${SENDGRID_FROM}" }

Codex uses TOML. Each server is a [mcp_servers.<name>] subtable.

~/.config/zed/settings.jsonjsonc

{
  "context_servers": {
    "sendgrid": {
      "command": {
        "path": "npx",
        "args": [
          "-y",
          "sendgrid-mcp"
        ]
      },
      "env": {
        "SENDGRID_API_KEY": "${SENDGRID_API_KEY}",
        "SENDGRID_FROM": "${SENDGRID_FROM}"
      }
    }
  }
}

Zed calls them "context_servers". Settings live-reload on save.

ChatGPT → Apps directorynone

SendGrid doesn't ship a hosted HTTPS endpoint today. ChatGPT supports remote MCP servers only — to use this server in ChatGPT you'll need to deploy it to a public HTTPS URL first (e.g. via Cloudflare Workers or Vercel) or wait for an official remote build.

Tools & permissions

Tool	Description	Args	Side effects
`send_mail`	Send a transactional email via the v3 Mail Send API.	to: string, subject: string, html: string	Write
`query_activity`	Search the Activity Feed by recipient, status, or time window.	query: object	Read
`list_suppressions`	List bounces, blocks, and spam reports.	type: string	Read
`verify_sender`	Check the verification status of a sender or domain.	sender: string	Read

Security & scope

Access scope: Read + write
Sandbox: Authenticates with a SendGrid API key scoped to the smallest necessary permissions. Send + read-stats by default; suppressions only when explicitly granted.
Gotchas: Never use a Full Access key — agents only need Mail Send + Stats Read.
SENDGRID_FROM must be a verified sender or domain; unverified senders fail with 403.
Activity Feed has a 30-day retention window — older events return empty without warning.

Agent prompt pack

— copy into Claude, Cursor, or ChatGPT.

Paste into Claude, Cursor, or ChatGPT. Edit the [brackets] before sending.

Recommend the best MCP servers for [task: e.g. email work] in [client: Claude].

Constraints:
- Prefer tools that are [official | open-source | read-only] — pick what matters for my use case.
- Exclude MCPs that require [e.g. a paid plan, OAuth-only flows, remote-only transport].
- Return at most 3 picks, ranked.

For each pick include:
1. One-sentence rationale.
2. The ready-to-paste install snippet for my client.
3. Any required secrets I need to create before installing.

Cross-check the top-mcps.com listing: https://top-mcps.com/top-mcps-for-email

Compare SendGrid against a real alternative. Swap the second MCP in [brackets] if you want a different match.

Compare SendGrid MCP vs [Resend MCP] for the following job: [describe the job, e.g. "let an agent create GitHub issues on bug triage"].

Judge them on:
- Setup time and complexity (what a new user hits first).
- Auth model (none / API key / OAuth 2.1) and credential risk.
- Transport (stdio / Streamable HTTP / SSE) and where the server runs.
- Required secrets and the blast radius if they leak.
- Operational risk in an unattended agent loop.
- Which one is "good enough" for a weekend prototype vs. production.

End with one sentence: which should I pick for my scenario, which is: [my scenario].

Asks the agent to install and verify. Works inside Claude Code, Cursor Agent, Codex CLI.

Install the SendGrid MCP server for my [client: Claude] at the default config path for that client.

Use the exact install snippet published at https://top-mcps.com/mcp/sendgrid (fetch https://top-mcps.com/mcp/sendgrid.json for the canonical server.json if you can read URLs).

Before finishing:
1. Create the required secrets (SENDGRID_API_KEY, SENDGRID_FROM) and put them in the appropriate env block — do not hard-code them.
2. Restart or reload the client so it picks up the new server.
3. Verify the server is connected (green / running state) and at least one tool is listed.
4. If anything fails, read the client's MCP logs and report the exact error — do not silently retry.

Confirm when done and list the tools the server now exposes.
