CMS Medicare Part D drug spending and prescriber data. 2024 quarterly data.
Overview
Remote MCP server giving assistants read access to CMS Medicare Part D drug spending, pricing trends and prescriber data through a single action-based tool.
- What you can do
- Look up drug spending details, full trend analysis and dataset statistics, and search drugs by name or rank top drugs by spending, beneficiaries or claims. Compare two drugs side by side and detect price outliers, including risers and fallers. Find generic alternatives for a brand drug and compare cost per beneficiary. Explore prescriber data by drug, state or NPI, plus specialty and geographic prescribing patterns. Review a manufacturer's full Part D portfolio and get a one-call dashboard summary of the landscape. Fall back to a raw CMS Data API action for anything not covered.
- When to use it
- Useful for health policy analysis, journalism or research on Medicare drug costs, and for comparing brand versus generic pricing or investigating prescribing patterns by specialty, state or provider. Worth adding when an assistant needs structured Medicare Part D figures rather than general web knowledge.
- Requirements
- A remote streamable HTTP endpoint; no API key, environment variables or headers are required. The README states it uses public CMS data and needs zero configuration.
Installation
In SourceWeft
- Open Partd Mcp in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.stayce%2Fpartd-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Other MCP clients
Add this to your client's mcpServers config.
