From a730ad188b2e47d17acb53f0c400377b972ed64b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marc-Andr=C3=A9=20Bombeck?= Date: Mon, 10 Aug 2026 01:10:52 +0200 Subject: [PATCH 1/5] feat(mcp): answer the visit history over the assistant wire Add get_visits, a bounded read of past visits (default the last 12 months, optional practitioner-name filter) returning date, status, kind, practitioner, specialty, the visit's own reason and outcome, and the linked condition labels, newest first. Absence is explicit: an account that has never recorded a visit reads { present: false }, never { present: true, visits: [] }. Fold upcoming appointments into get_preventive_care as their own named field rather than minting a second due-list tool, so a question about what is coming up gets one answer. The Vorsorge arm stays free of ENCOUNTER-origin reminders; the appointments are read from Encounter directly. Reason and outcome ride the USER_TEXT wrapping, and every row is scoped to the caller by construction. --- docs/api/mcp-capabilities.md | 45 +++--- src/app/mcp/__tests__/route.test.ts | 2 + src/lib/mcp/__tests__/tools.test.ts | 169 ++++++++++++++++++++ src/lib/mcp/tools.ts | 240 +++++++++++++++++++++++++++- 4 files changed, 429 insertions(+), 27 deletions(-) diff --git a/docs/api/mcp-capabilities.md b/docs/api/mcp-capabilities.md index e467969bf..2117f6b8b 100644 --- a/docs/api/mcp-capabilities.md +++ b/docs/api/mcp-capabilities.md @@ -66,28 +66,29 @@ optional so a `{ present: false }` miss and a full hit both validate. argument.
