# Medicare Part D MCP Server
**15 actions. $200B+ in drug spending data. One tool call.**
A Model Context Protocol (MCP) server giving AI assistants instant access to CMS Medicare Part D drug spending, prescriber, and pricing trend data — deployed on Cloudflare Workers with sub-50ms global response times.
**Live endpoint:** `https://mcp-partd.medseal.app/mcp`
No API key required. Public CMS data. Zero configuration.
## What Can It Do?
**Spending Analysis**
Get current quarterly spending or full multi-year trend analysis for any Part D drug. Covers 2024 Q1-Q4 quarterly data and 2019-2023 annual trends.
**Drug Comparison**
Compare two drugs side-by-side: total spending, beneficiaries, cost per claim, year-over-year changes, and 4-year CAGR — all in one call.
**Price Outlier Detection**
Surface drugs with the biggest price increases or decreases. Filter by risers, fallers, or both. Powered by CMS year-over-year change data.
**Generic Alternative Finder**
Given any brand-name drug, find all drugs sharing the same generic compound and compare costs per beneficiary. Shows potential savings percentage.
**Prescriber Intelligence**
Look up who prescribes what — by drug name, by state, or by NPI. Aggregate prescribing data with top drugs per provider.
**Specialty Breakdown**
See which medical specialties prescribe a drug the most. Aggregated by provider type with claim counts and cost totals.
**Geographic Patterns**
Prescribing data broken down by state — see where drugs are prescribed most heavily across the US.
**Manufacturer Portfolio**
Look up any drug manufacturer to see their full Part D portfolio: all drugs, combined spending, beneficiary counts.
**Dashboard Summary**
One-call overview of the entire Part D landscape: top drugs by spending, most prescribed by beneficiaries, biggest price movers.
**Top Rankings**
Rank drugs by spending, beneficiaries, or claims. Sortable. Configurable result count.
