Prerequisites: Install pflow before continuing.
Claude Desktop connects to pflow via MCP server. This gives Claude access to pflow’s workflow discovery and execution tools.
pflow is currently verified to work on macOS. Windows and Linux support is coming soon.

​
Setup

​
1. Open your MCP config file

The config file is located at: 
~/Library/Application Support/Claude/claude_desktop_config.json
You can also access it through Claude Desktop: Settings → Developer → Edit Config.

​
2. Add pflow to your config

Add the pflow server to your mcpServers object: 
{
  "mcpServers": {
    "pflow": {
      "command": "pflow",
      "args": ["mcp", "serve"]
    }
  }
}
If you have other MCP servers configured, add pflow alongside them: 
{
  "mcpServers": {
    "existing-server": {
      "command": "...",
      "args": ["..."]
    },
    "pflow": {
      "command": "pflow",
      "args": ["mcp", "serve"]
    }
  }
}

​
3. Restart Claude Desktop

Completely quit Claude Desktop and restart it. The app needs to restart to load the new MCP server.

​
4. Verify installation

Start a new conversation and ask Claude to list available pflow workflows: 
Use pflow to list available workflows
Claude should be able to access pflow’s tools and respond with workflow information.

​
Troubleshooting

  1. Make sure pflow is installed and in your PATH: pflow --version
  2. Check your JSON syntax is valid (use a JSON validator)
  3. Completely quit and restart Claude Desktop (not just close the window)
Open Claude Desktop, go to Settings → Developer → Edit Config. Claude will create the file for you.
