Connecting PF Create to Langflow

Difficulty: Easy — drag in an MCP component from the Langflow canvas.
Requires: Langflow v1.8+ (Cloud or self-hosted)

Before You Start

• Your pfk_… API key — find it on your account page

Steps

1. Open Langflow and create or open a flow.
2. Search for MCP Tools or MCP Client in the component panel and drag it onto the canvas.
3. Connect it to your Agent component.
4. In the MCP component settings:
   • Transport: SSE
   • URL: https://mcp.pfcreate.ca/sse
   • Headers: Authorization: Bearer pfk_YOUR_KEY_HERE
5. Click Check Connection — PF Create tools will be listed automatically.

Troubleshooting

MCP component not available — Update Langflow to v1.8+.

Connection failed — Verify the SSE URL is correct and your pfk_ key is valid.

401 errors — Confirm the full pfk_ prefix is present in your key.
