# seed-mcp

MCP server over the public catalogs of major US row-crop seed
vendors — corn, soybeans, wheat. Sibling project to
[`crop-chem-docs`](https://git.jpaul.io/justin/crop-chem-docs)
(pesticide labels), feeding the same Drawbar farm-advisor AI.

The server exposes per-variety records with **agronomic ratings**,
**disease tolerance**, **trait stack**, **maturity**, and
**regional notes** — so the advisor can answer questions like
"which corn hybrid for sandy soil, drought-prone, RM ≤105 in
northeast Iowa?" without rummaging through individual brand sites.

## Vendor coverage

| Vendor | Verdict | Varieties | Notes |
|---|---|---|---|
| Bayer seeds (DEKALB + Asgrow + WestBred) | 🟢 | ~475 | Same `cropscience.bayer.us` Next.js infra as crop-chem-docs |
| Golden Harvest (Syngenta) | 🟢 | ~175 | Sitemap + server-rendered HTML + Syngenta CDN PDFs |
| NK (Syngenta) | 🟢 | 29 | Shares PDF fetcher with Golden Harvest |
| AgriPro (Syngenta wheat) | 🟢 | 24 | Drupal Views, server-rendered |
| Beck's PFR | 🟡 | 2,089 | Public Sanity GROQ API (no auth) |
| Beck's products | 🟡 | 860 | Identity-only until SeedIQ XHR sniffed |
| Pioneer (Corteva) | 🔴 | — | ToS bans automation — curated fallback lesson instead |

## Quick start

```bash
git clone https://git.jpaul.io/justin/seed-mcp.git
cd seed-mcp
python -m venv venv && source venv/bin/activate
pip install -r requirements.txt

# Run one scraper
python -m scrape.runner --source bayer_seeds --force

# Rebuild indexes
python -m rag.index --rebuild

# Local MCP server (stdio for Claude Desktop dev)
python -m docs_mcp.server --transport stdio
```

## Tools exposed

| Tool | Purpose |
|---|---|
| `search_docs` | Hybrid + rerank variety search with crop / RM / trait / region filters |
| `get_page` | Full variety record by `(source, source_key)` |
| `list_versions` | Discover crops, brands, traits, RM/MG ranges, wheat classes |
| `corpus_status` | Counts + freshness; useful for health probes |
| `crop_seed_api_lessons` | Curated agronomy lessons — Pioneer fallback, disease-scale normalization, regional placement heuristics |

## Build phases

This is a clone of [`docs-mcp-template`](https://git.jpaul.io/justin/docs-mcp-template).
The 13 phases in `PLAN.md` apply:

| Phase | Status |
|---|---|
| 0 — scaffold | done |
| 1 — first scraper (bayer_seeds) | next |
| 2 — chunk + index | pending |
| 3 — baseline MCP tools | template defaults |
| 4-5 — Dockerfile + CI | done (placeholders filled) |
| 6 — reranker | shares `llama-rerank` sidecar with crop-chem-docs |
| 7 — eval harness | pending (curate ~25 queries) |
| 8 — hybrid search | done (template) |
| 9 — diff_versions, list_cluster | optional |
| 11 — `crop_seed_api_lessons` curated layer | pending |

See `CLAUDE.md` for the canonical sidecar schema and the
disease-scale-normalization gotcha (Golden Harvest is reversed).

## Infrastructure

- **Registry**: `git.jpaul.io/justin/seed-mcp:latest` (Watchtower) /
  `:corpus-YYYY.MM.DD` (production pin)
- **Embedder**: shared Ollama pool with crop-chem-docs (Gitea-host
  GPUs + Windows Ollama; CI never hits trashpanda's production Ollama)
- **Reranker**: shared `llama-rerank` sidecar on trashpanda's Tesla
  P4 (one container, both MCPs use it)
- **PRODUCT_NAME**: `crop_seed` (not `seed_mcp` — used in Chroma
  collection, BM25 db filename, and `crop_seed_api_lessons` tool)
