Security Report
CropGraph MCP is a well-designed agricultural intelligence server with strong security fundamentals. The codebase is purely offline with no external API calls, no authentication required (appropriate for its use case), and no sensitive credential handling. Input validation is present throughout tool implementations. Minor code quality observations exist around broad exception handling and logging patterns, but these do not constitute security vulnerabilities. Supply chain analysis found 3 known vulnerabilities in dependencies (2 critical, 0 high severity). Package verification found 1 issue (1 critical, 0 high severity).

Data
| Asset | Count | Notes |
|---|---|---|
| Crop calendar | 5,006 entries | 14 categories (vegetable, herb, fruit, flower, cover-crop, root, legume, grain, mushroom, native, medicinal, fiber, forage, sprout). Frost-anchored windows; 120 entries carry climate modifiers across 6 climate types |
| Companion relationships | 1,004 | 510 beneficial, 95 antagonist, 12 mechanism categories |
| Growing degree days | 120 models | Cultivar-specific GDD ranges, base temperatures, NOAA Climate Normals harvest prediction |
| Rotation families | 12 | Nightshades, brassicas, cucurbits, alliums, legumes, umbellifers, grasses, amaranthaceae, composites, mints, malvaceae, miscellaneous. Every calendar slug mapped. |
| Succession chains | 33 | Greens, roots, legumes, brassicas, cucurbits, herbs, flowers, cover crops. Frost-anchored phases with per-climate notes. |
| Pest/disease associations | 506 | Crop-to-pest edges with diagnostic symptoms, organic management, prevention, and regions. OMRI-listed management only. |
| Beneficial insects | 200 entries | Predators (62), parasitoids (40), pollinators (50), decomposers (29), microbial controls (22). Prey and attractant cross-references; composite "now what?" intelligence layer with hand-authored notes for the top 40 pest slugs. |
| USDA hardiness zones | 40,283 ZIPs | PRISM 2023 + waldoj/frostline centroids, offline lookup |
| Climate classifier | 6 types | Maritime, mediterranean, continental, humid subtropical, arid, semi-arid |
