Hackle MCP Server

[smithery badge]

[!WARNING]

⚠️ This local npm package is deprecated — use the remote MCP server

The Hackle MCP server is now available as a remote server, and this local npm package is deprecated. The remote server requires no npm or Node.js setup, updates automatically, works in the browser, and is where all new tools (such as messaging statistics and Kakao/Text message queries) ship.

This package will no longer receive updates or new tools. Existing installations keep working for now, but please migrate to the remote server.

👉 Migration guide: https://docs.hackle.io/external-link/model-context-protocol/migration

How to connect to the remote server

1. Add a custom connector in claude.ai (web) or Claude Desktop via Customization → Connectors → + Add Custom Connector, using the remote MCP server URL:

   https://mcp.hackle.io/mcp

2. Enter your existing Hackle API key in the authentication screen — your API key remains unchanged.

3. Once connected, you can optionally remove the local server entry from your claude_desktop_config.json.
