Summary
A comprehensive genomics toolkit that wires Claude into 11 plant biology databases: Ensembl Plants, Phytozome, UniProtKB, Europe PMC, QuickGO, NCBI BLAST, Gramene, KEGG, STRING-DB, ATTED-II, and BAR. You pass it a locus identifier like AT1G01010 and get back gene metadata, cross-references, protein records, literature mentions, GO annotations, homology trees, pathway memberships, protein interactions, coexpression neighbors, and tissue-specific expression profiles. The 32 tools split into single lookups, parallel batch operations, and cross-source synthesis calls that merge data from multiple backends. Reach for this when you're doing comparative plant genomics, pathway analysis, or need to pull together fragmented annotations across disparate public repositories without writing custom scrapers for each one.

Free, public sources: Ensembl Plants, Phytozome BioMart, UniProtKB, Europe PMC, QuickGO, Planteome, PlantCyc/PMN, g:Profiler, NCBI BLAST, Gramene, JASPAR, KEGG, STRING-DB, ATTED-II, ThaleMine, and BAR (Bio-Analytic Resource for Plant Biology).

💬 Try it
Once connected, ask Claude a plain-language question — you don't have to name any tool or remember the chain:
"Tell me everything about the Arabidopsis gene AT1G01010 — its function, GO terms, KEGG pathways, protein-interaction partners, and recent papers."
Claude fans out across Ensembl Plants, UniProt, QuickGO, KEGG, STRING-DB,
and Europe PMC in a single turn and hands back one synthesized answer.
Swap in any locus and pass organism= for cross-species — e.g. rice
Os01g0100100 (oryza_sativa) — and it routes to the right backends
automatically.
🛠️ Tools
50 tools across 23 backends — Ensembl Plants, Phytozome BioMart,
UniProtKB, Europe PMC, QuickGO, Planteome, PlantCyc/PMN, g:Profiler,
AlphaFold DB, PDBe, InterPro, JASPAR, PANTHER, OrthoDB, AraGWAS, 1001 Genomes, NCBI BLAST,
Gramene, KEGG, STRING-DB, ATTED-II, ThaleMine, BAR.
28 single-locus + 1 motif lookup + 1 region query + 1 variant annotator + 1 gene-set
enrichment + 1 BLAST search + 12 parallel-batch + 5 cross-source synthesis. Most take a
TAIR-style locus (e.g. AT1G01010) plus
optional organism= (slug / scientific name / common name / NCBI taxid
— 12-plant curated coverage matrix at the pgmcp://organisms/coverage
MCP resource). All publish JSON outputSchema, EDAM ontology tags, and
behaviour annotations — every tool is readOnlyHint + openWorldHint, so
hosts can surface them without a destructive-action confirmation prompt.

📚 Resources & prompts
Four read-only MCP resources + three parameterized prompts
Clients discover them via resources/list and prompts/list.
Resources (resources/read):
| URI | What |
|---|---|
pgmcp://cache/stats | Per-backend TTLCache rollup — {hits, misses, size} for each live backend. |
pgmcp://organisms/phytozome | Slug → Phytozome organism_id map. |
pgmcp://backends/status | Per-backend liveness rollup — name, base_url, kind, subscription_gated. |
pgmcp://organisms/coverage | Markdown table of all 12 supported plants × 9 ID slots (ncbi_taxid / ensembl / phytozome / string / europe_pmc / kegg / atted / gprofiler / plantcyc). |
Prompts (prompts/get):
| Name | Required | Optional | Chains |
|---|---|---|---|
analyze_locus | locus | organism (default arabidopsis_thaliana) | Ensembl → xrefs → UniProt → Europe PMC → QuickGO. |
find_homologs | sequence | program (default blastp) | blast_sequence → per-hit resolve_locus_to_uniprot for UniProt-shaped accessions. |
biological_context | locus | top_n (default 10) | Gramene → KEGG → UniProt → STRING → ATTED-II. |
🔌 Transports
| Transport | How to launch |
|---|---|
| stdio (default) | plant-genomics-mcp (after install) or via Docker above |
| streamable-HTTP | plant-genomics-mcp-http — POST JSON-RPC at http://host:port/mcp |
The HTTP transport is stateless and emits JSON responses by default — the right shape for registry indexers and remote hosting.
Hosted endpoint
A small personal demo runs at:
https://mjarnoldgt76.tail86d19d.ts.net/mcp
Intended for registry indexers, one-off evaluation, and quick interactive testing — not for production workloads. No SLA, no uptime commitment, URL may change without notice (single laptop on a residential connection).
# liveness probe
curl https://mjarnoldgt76.tail86d19d.ts.net/healthz
# {"status":"ok"}
# connect from Claude Code
claude mcp add --transport http plant-genomics-mcp \
https://mjarnoldgt76.tail86d19d.ts.net/mcp
For anything beyond casual evaluation, self-host. The HTTP transport
is the same binary; self-hosting buys deterministic uptime, your own
bearer-token gate (PLANT_GENOMICS_MCP_HTTP_TOKEN), and NCBI BLAST
etiquette under your own contact email.
⚙️ Configuration
Stdio needs no configuration. The two env vars that matter:
| Variable | When | Effect |
|---|---|---|
PLANT_GENOMICS_MCP_HTTP_TOKEN | HTTP transport only | Bearer token for /mcp; must be ≥32 chars or the HTTP server aborts at startup. Generate openssl rand -hex 32. |
PLANT_GENOMICS_MCP_NCBI_EMAIL | If you use BLAST | NCBI etiquette contact. Unset → placeholder + per-call warning; NCBI may throttle. |
All env vars (HTTP bind, body cap, cache, BLAST concurrency)
| Variable | Default | Effect |
|---|---|---|
PLANT_GENOMICS_MCP_HTTP_HOST | 127.0.0.1 | HTTP bind address. |
PLANT_GENOMICS_MCP_HTTP_PORT | 8765 | HTTP TCP port. |
PLANT_GENOMICS_MCP_HTTP_MAX_BODY | 2097152 (2 MiB) | Reject POSTs with Content-Length larger than this. |
PLANT_GENOMICS_MCP_HTTP_STATELESS | 1 | 0 keeps per-client session state (SSE-style). |
PLANT_GENOMICS_MCP_HTTP_JSON | 1 | 0 switches the response shape to streaming SSE events. |
PLANT_GENOMICS_MCP_BLAST_CONCURRENCY | 2 | Max in-flight BLAST searches per process (NCBI per-IP rate limit). |
PLANT_GENOMICS_MCP_CACHE_TTL | 600 | Per-backend TTL+LRU cache entry lifetime, in seconds. 200-only. |
PLANT_GENOMICS_MCP_CACHE_SIZE | 256 | Max entries per backend before LRU eviction. |
PLANT_GENOMICS_MCP_CACHE_DISABLED | unset | Any non-empty value makes every cache a no-op. |
The cache is process-local — restart the server to drop all entries.
Long-running calls (retry storms, multi-second Phytozome BioMart POSTs)
emit MCP notifications/progress over the active session; clients opt
in via progressToken in the request _meta.
⚠️ Error model
Wire-prefix taxonomy + batch result shape
All live tools raise PlantGenomicsError subclasses; the MCP SDK
stringifies them into the wire content with a [ClassName] prefix so
clients can route on failure kind without parsing the message:
| Wire prefix | When |
|---|---|
[NotFoundError] | 404 / empty BioMart row / invalid locus identifier |
[RateLimitError] | 429 retry budget exhausted — back off and retry |
[UpstreamUnavailableError] | 5xx past retry budget — service outage, try a peer backend |
[PlantGenomicsError] | Other (BioMart Query ERROR: body, unexpected column count, etc.) |
Batch tools return {tool, count, results, errors} where
results[locus] is the same shape as the single-locus tool and
errors[locus] is the same [ClassName] message string. Ensembl's
batch uses the native POST /lookup/id endpoint (one HTTP round-trip);
everything else fans out via asyncio.gather.
🧪 Development
.venv/bin/pip install -e '.[dev]' # or: uv sync --extra dev
.venv/bin/pytest -q # unit tests
PLANT_GENOMICS_MCP_LIVE=1 .venv/bin/pytest -q # adds live network probes
PLANT_GENOMICS_MCP_STDIO_SMOKE=1 .venv/bin/pytest -q # adds stdio smoke
.venv/bin/ruff check .
With uv, pass --extra dev — a bare uv sync omits (and removes) the test
dependencies. See CONTRIBUTING.md.
CI runs the unit suite + the stdio smoke on every push/PR (matrix:
Python 3.11, 3.12, 3.13, 3.14 — the full requires-python range). The
live-network gate is not run in CI to avoid flakes from upstream
availability.
Scientific validation / drift detection. scripts/benchmark_annotations.py
drives a curated corpus of canonical loci (27, spanning all 12 organisms)
through every backend + synthesis pipeline and compares results to a frozen
baseline, emitting PASS / DRIFT / FAIL plus cross-source consistency
invariants. It's how upstream data drift is caught. A scheduled GitHub Actions
workflow (.github/workflows/benchmark.yml) runs it weekly and pages on a
confirmed regression. Operator guide: docs/benchmarking.md.
.venv/bin/python scripts/benchmark_annotations.py # full live sweep (~3-5 min)
See CHANGELOG.md for release notes, including the
v0.8 → v0.9 species=/organism_id= → organism= migration and the
v1.0.1 HTTP-token enforcement change.
