How it works

Connect your AI agent to SendCore via MCP, REST API, or SDKs — no manual API calls needed.

Generate Key

Create an API key from your SendCore dashboard.

Choose Your Connection

Use MCP (Claude, Cursor), REST API (OpenAI, LangChain), or SDKs (Node, Python, Go, PHP, Java).

Ask in Natural Language

Tell your AI agent what to do — "Send a welcome email to new subscribers"

Agent Executes

The AI agent calls SendCore APIs directly. No code to write.

8 tools at your agent's disposal

Every essential SendCore feature is exposed via MCP — send emails, manage inboxes, control workflows.

Email

send_email
Send transactional emails with HTML or plain text
email_logs
Check recent delivery status and timestamps

Workflows

list_workflows
List automation workflows with status
create_workflow
Create workflows with any trigger type
activate_workflow
Activate a workflow to start running

Agent Inboxes

create_inbox
Create an email inbox for your AI agent
list_inboxes
View all agent inboxes and their addresses
read_emails
Read inbox emails with semantic search

Claude Setup

Connect via the hosted gateway with OAuth (no API key needed), or run locally with stdio.

Full documentation

Option A — Hosted (OAuth)

{
  "mcpServers": {
    "sendcore": {
      "type": "http",
      "url": "https://mcp.usesendcore.com/mcp/v1/protocol"
    }
  }
}

Option B — Local (API key)

{
  "mcpServers": {
    "sendcore": {
      "command": "npx",
      "args": ["-y", "sendcore-mcp"],
      "env": {
        "SENDCORE_API_KEY": "sc_mcp_your_key_here"
      }
    }
  }
}

Online MCP Inspector

Test the MCP server from your browser using the MCP Inspector or any MCP-compatible HTTP client.

Full documentation

Connect to our hosted gateway at https://mcp.usesendcore.com using the Streamable HTTP transport:

npx @modelcontextprotocol/inspector \
  --transport http \
  --url https://mcp.usesendcore.com/mcp/v1/protocol \
  --header "Authorization: Bearer sc_mcp_your_key_here"

REST API & SDKs

Use the SendCore REST API directly with any AI framework that supports function calling, or integrate via our official SDKs.

OpenAI Function Calling

{
  "tools": [{
    "type": "function",
    "function": {
      "name": "send_email",
      "description": "Send a transactional email",
      "parameters": {
        "type": "object",
        "properties": {
          "from": { "type": "string" },
          "to": { "type": "array", "items": { "type": "string" } },
          "subject": { "type": "string" },
          "html": { "type": "string" }
        },
        "required": ["from", "to", "subject", "html"]
      }
    }
  }]
}

SDK Quick Example

# Any AI agent can call SendCore via SDK
from sendcore import SendCore

client = SendCore("your-api-key")
result = client.emails.send(
    from_addr="hello@yourdomain.com",
    to=["user@example.com"],
    subject="Hello from AI",
    html="<h1>Hello World</h1>",
)
print(result["id"])

Example prompts to try

"Send a welcome email to user@example.com with subject Welcome! and HTML body '<h1>Hello!</h1>'"

"What are my recent email logs? Show me the last 10 deliveries."

"List my sending domains and check if they're verified."

"Add example.com as a new domain and show me the DNS records I need."

"Create a campaign called April Newsletter. Set subject to 'April Updates'."

"Create a VIP Customers audience list and add jane@example.com to it."

"List my automation workflows. Activate the welcome sequence."

"Pause all running workflows."
