There is no CMS-published MCP server. The CMSgov GitHub organization has no MCP repository; the npm registry returns no @cmsgov or CMS-maintained MCP package; nothing on developer.cms.gov, bluebutton.cms.gov, bcda.cms.gov, ab2d.cms.gov, dpc.cms.gov or data.cms.gov advertises an MCP endpoint; and no probed host serves /.well-known/ai-plugin.json or an agent card that could point at one. Third-party MCP servers wrapping Medicare data exist on npm (@pipeworx/mcp-medicare-coverage, @mymedi-ai/mcp-server) but they are NOT CMS products and are deliberately excluded — listing them here would credit CMS with an agent surface it does not ship. The tools[] below are therefore a DERIVED candidate mapping of existing REST operations, not a server anyone can call. deployment: mode: none auth: unknown verified: derived note: >- No hosted endpoint and no installable package exist. mode is none because CMS ships nothing; the endpoint and install fields are deliberately left empty rather than guessed. server: name: cms transport: null url: null tools: - name: bcda_export_group_claims description: >- Start a Bulk FHIR export job for all Medicare enrollees attributed to the calling model entity (/Group/all) or for prior-year runout enrollees (/Group/runout).
