Each of these is one operation on one endpoint, available both as a workflow step and as a tool an AI agent can call on its own. Nothing bundles several operations into one action, so what a run did stays readable afterwards.

SendGrid API rate limits

600 requests per minute

Default rate limit is 600 requests per minute for most v3 endpoints; the /v3/mail/send endpoint has no rate limit. Limits vary by plan and per endpoint. Exceeding returns HTTP 429. Headers: X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset. Per Twilio SendGrid docs (2026).

These are the limits SendGrid documents, not ones LiveContext measured. They can change and often depend on your plan, so check the SendGrid documentation for current values.

Use SendGrid from Claude Code, Cursor or Codex

Connect SendGrid in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its SendGrid operations become tools the client can call, next to every other integration you connected.

Claude Code

claude mcp add --transport http livecontext https://livecontext.ai/mcp --header "X-API-Key: YOUR_API_KEY"

Codex (~/.codex/config.toml)

[mcp_servers.livecontext]
url = "https://livecontext.ai/mcp"

[mcp_servers.livecontext.http_headers]
"X-API-Key" = "YOUR_API_KEY"

Cursor, Claude Desktop and other JSON configs

{
  "mcpServers": {
    "livecontext": {
      "type": "http",
      "url": "https://livecontext.ai/mcp",
      "headers": {
        "X-API-Key": "YOUR_API_KEY"
      }
    }
  }
}
