Health Claims FastMCP (Mock)

Sample MCP server for the health insurance claims domain. This server uses FastMCP and exposes multiple mock tools for claims, benefits, providers, and prior authorizations. All data is synthetic and for demo use only.

Setup

python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

Run (stdio)

python server.py

Run (streamable HTTP)

FastMCP supports streamable-http and sse transports. Use env vars to switch transport and control host/port.

export MCP_TRANSPORT=streamable-http
export FASTMCP_HOST=127.0.0.1
export FASTMCP_PORT=8000
python server.py

The Streamable HTTP endpoint defaults to:

http://127.0.0.1:8000/mcp

You can override it via FASTMCP_STREAMABLE_HTTP_PATH.

export FASTMCP_STREAMABLE_HTTP_PATH=/mcp

Notes

• The server uses FastMCP (mcp.server.fastmcp.FastMCP) with @mcp.tool() decorators as described in the MCP build-server docs.
• The mock logic is deterministic and in-memory; no external calls or PHI.
