MCP Overview

Connect FHIRfly to AI assistants using the Model Context Protocol.

What is MCP?

The Model Context Protocol (MCP) is an open standard that allows AI assistants to securely access external tools and data sources. FHIRfly's MCP integration lets AI assistants like Claude look up healthcare reference data directly.

Benefits

Real-time data: AI gets current NDC, NPI, and other reference data
Accurate citations: Full provenance information for reliable sourcing
Seamless experience: No copy-pasting between apps
Secure access: Uses your API credentials with proper scoping
