FineRx

MCP · Model Context Protocol

Connect FineRx to your AI assistant

Give Claude, ChatGPT, Cursor, or any MCP-compatible client live access to FineRx's US prescription price data — drug search, pharmacy-vs-savings-program price comparisons, foreign-brand analogs, and nearby pharmacies. Every answer carries an attribution and a not-medical-advice line.

Option 1 — Hosted server (recommended)

A hosted Streamable-HTTP endpoint. Nothing to install, no key to manage — the server holds its own key and only ever returns already-public data.

Server URL: https://www.finerxfinder.com/mcp

In clients that support remote MCP connectors (for example Claude's Connectors or ChatGPT's custom connectors), add a custom connector and paste the URL above. For config-file clients that only speak stdio (Cursor, Windsurf, and others), bridge to it with mcp-remote:

{
  "mcpServers": {
    "finerx": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://www.finerxfinder.com/mcp"]
    }
  }
}

Option 2 — Local server (finerx-mcp)

Run the open-source finerx-mcp package on your own machine over stdio. It is a thin client over the public API and needs a free developer key.

{
  "mcpServers": {
    "finerx": {
      "command": "uvx",
      "args": ["finerx-mcp"],
      "env": { "FINERX_API_KEY": "frx_live_..." }
    }
  }
}

Or run it directly: FINERX_API_KEY=frx_live_... uvx finerx-mcp. Request a free key on the Developers page.

What your assistant can do

The server exposes five read-only tools:

  • search_drugs — find medications by name (brand, generic, or foreign brand)
  • get_drug — a drug's packages, strengths, and forms
  • compare_prices — pharmacy-vs-savings-program prices for an NDC, with observation dates
  • find_nearby_pharmacies — pharmacy locations near a ZIP (chain-level, no tracking)
  • get_dataset_info — dataset size, coverage, and freshness

Where it's listed

  • Official MCP registry: com.finerxfinder/finerx
  • PyPI: finerx-mcp

Terms

Free to use, with three rules that keep FineRx honest:

  • Attribute prices to FineRx (every response already embeds the line).
  • Prices are recently observed estimates that may change — never guarantees.
  • FineRx gives no medical advice; it compares prices, nothing more.
