From e062721812f566f178c65194f9c95239e8ed5eee Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marc-Andr=C3=A9=20Bombeck?= Date: Sat, 18 Jul 2026 07:35:06 +0200 Subject: [PATCH] feat(mcp): add get_nutrients read tool MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds MCP coverage for the NutrientIntakeDay pipeline (water, caffeine, 24 micronutrients) — previously fully unreachable over MCP, and search("water") / search("vitamin") silently miscollided or read as honest absence even for a daily logger. get_nutrients is a thin facade over the same two reads GET /api/nutrients and GET /api/nutrients/daily run: the tz-anchored day-key math, the sum-across-sources fold, and the sex-aware EFSA reference resolution. Gated on the opt-in nutrients module, mirroring both backing routes. Discoverable via search (a grouped presence probe) and fetch, plus a healthlog://nutrient/{code} resource template with completion + listing scoped to the user's own logged codes. --- src/lib/mcp/__tests__/nutrients-read.test.ts | 174 +++++++++++ .../mcp/__tests__/resource-templates.test.ts | 65 ++++ src/lib/mcp/__tests__/search-fetch.test.ts | 11 + src/lib/mcp/__tests__/tools.test.ts | 163 ++++++++++ src/lib/mcp/nutrients-read.ts | 286 ++++++++++++++++++ src/lib/mcp/resources.ts | 55 ++++ src/lib/mcp/server.ts | 2 +- src/lib/mcp/tools.ts | 174 +++++++++++ 8 files changed, 929 insertions(+), 1 deletion(-) create mode 100644 src/lib/mcp/__tests__/nutrients-read.test.ts create mode 100644 src/lib/mcp/nutrients-read.ts diff --git a/src/lib/mcp/__tests__/nutrients-read.test.ts b/src/lib/mcp/__tests__/nutrients-read.test.ts new file mode 100644 index 000000000..921dbc6a5 --- /dev/null +++ b/src/lib/mcp/__tests__/nutrients-read.test.ts @@ -0,0 +1,174 @@ +import { describe, it, expect, vi, beforeEach } from "vitest";
