FixPayment MCP Server

A FastMCP server exposing a creditor-facing API for the FixPayment portal.

Connect any MCP-enabled AI assistant (e.g. Claude) to your FixPayment account to create accounts, update statuses, and run reports — all in plain English.

• MCP server URL: `http://fixpayment.org:8000`
• Docs: `https://fixpayment.org/mcp/fixpayment-mcp.html`
• Support: support@fixpayment.org

Quick Start

# 1. Clone & install dependencies
pip install -r requirements.txt

# 2. Configure credentials
cp .env.example .env
# Edit .env and set FIXPAYMENT_DB_* variables

# 3. Run the server
python -m mcp.server
# or via FastMCP CLI:
fastmcp run mcp/server.py:mcp

Environment Variables

Auth Model

Every MCP tool requires an `api_key` argument.

The key maps to a `creditor_id` and a `plan` (`basic`, `reports`, or `full`) in the `mcp_api_keys` table.
