PayVoice Collections MCP Server

This project provides a small HTTP service that exposes a save_collection tool and stores collection data in the Supabase public.collections table.

1. Local setup

python -m venv .venv
# Windows:
.venv\Scripts\activate
# macOS/Linux:
# source .venv/bin/activate

pip install -r requirements.txt

Set environment variables:

SUPABASE_URL=https://YOUR_PROJECT.supabase.co
SUPABASE_KEY=YOUR_SUPABASE_PUBLISHABLE_KEY

Run:

uvicorn server:app --reload --port 8000

Health check:

http://localhost:8000/health

Related MCP server: expense-tracker

2. Deploy

You can deploy the included render.yaml to Render or deploy the same FastAPI app to another HTTPS host.

Set these environment variables on the host:

• SUPABASE_URL

• SUPABASE_KEY

Your deployed URL will look like:

https://YOUR-SERVICE.onrender.com

The endpoint included for the simple JSON MCP-style test is:

https://YOUR-SERVICE.onrender.com/mcp

3. Important Inya note

Before entering /mcp into Inya, verify which MCP transport/protocol version your Inya workspace requires. A generic HTTP JSON endpoint is not automatically equivalent to an official MCP Streamable HTTP/SSE endpoint.

If Inya rejects this URL as an invalid MCP server, the server needs to be adapted to the exact MCP transport supported by your Inya workspace.
