MCP Setup

Connect Threadline's persistent memory layer to any MCP-compatible client like Cursor or Claude Desktop. Setup takes under a minute.

One-line install

Run the Threadline MCP server with no install step required:

npx -y @threadline/mcp

Set your API key

The MCP server authenticates using a single environment variable. Grab your key from the dashboard.

export THREADLINE_API_KEY="tl_live_..."

Claude Desktop

Add the following to your claude_desktop_config.json file. On macOS this lives at ~/Library/Application Support/Claude/claude_desktop_config.json.

{
  "mcpServers": {
    "threadline": {
      "command": "npx",
      "args": ["-y", "@threadline/mcp"],
      "env": {
        "THREADLINE_API_KEY": "tl_live_..."
      }
    }
  }
}

Restart Claude Desktop. You should see Threadline's tools appear in the MCP menu.

Cursor

In Cursor, open Settings → MCP → Add new MCP server and paste the same JSON snippet, or add it to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "threadline": {
      "command": "npx",
      "args": ["-y", "@threadline/mcp"],
      "env": {
        "THREADLINE_API_KEY": "tl_live_..."
      }
    }
  }
}
