SendSoon AI MCP

English | 简体中文 | 日本語

SendSoon MCP is a Model Context Protocol (MCP) server that lets Codex, Claude, and WorkBuddy use SendSoon capabilities: send email, look up public IPs, and convert local documents to Markdown.

Configure it once, then describe tasks in natural language. You usually do not need to mention SendSoon in every prompt.

What you can do

Everyday examples

Send an email to [email protected] with the subject “Meeting reminder” and the body “The meeting starts at 3 PM today.”

Look up the location and ISP for 8.8.8.8.

Convert /path/to/report.pdf to Markdown and summarize the key points.

If the agent does not select a tool automatically, say:

Use the sendsoon MCP to complete this task.

The instructions below cover Codex, Claude Desktop, and WorkBuddy.

Codex

Config file: user-level ~/.codex/config.toml (macOS / Linux) or %USERPROFILE%\.codex\config.toml (Windows).

[mcp_servers.sendsoon]
command = "npx"
args = ["-y", "@sendsoon/mcp"]

[mcp_servers.sendsoon.env]
SENDSOON_API_KEY = ""

Verify: Save the file, restart Codex, and run /mcp in a chat. You should see sendsoon connected. In the desktop app, also check Settings > MCP servers.

First use: Start a new conversation and ask for a simple task (e.g. “Look up 8.8.8.8”). Approve the tool if Codex asks for permission.

Claude Desktop

Config file:

You can also open Settings > Developer > Edit Config inside Claude Desktop.

{
  "mcpServers": {
    "sendsoon": {
      "command": "npx",
      "args": ["-y", "@sendsoon/mcp"],
      "env": {
        "SENDSOON_API_KEY": ""
      }
    }
  }
}

Verify: Save the file, fully quit Claude Desktop (including the system tray), then relaunch. Start a new chat and confirm sendsoon tools appear in the tools menu or settings.

First use: Claude may ask to approve tool access on the first invocation; allow it to continue.

WorkBuddy

WorkBuddy can add SendSoon by pasting the connector JSON directly in MCP Server Management.

Config file: %USERPROFILE%\.workbuddy-ai\mcp.json (Windows) or ~/.workbuddy-ai/mcp.json (macOS / Linux).

1. Open WorkBuddy and go to MCP Server Management.
2. Click Add MCP.
