Overview

Description from the maker (original English)

MCP gateway federating 22 biomedical MCP servers behind one endpoint: gnomAD, ClinVar, HPO, VEP.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Before you install

  • Basic checks: 3 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

What it can do

The server asks you to sign in before it lists its tools.

Compared with others in Clinics & healthi

  • More stars than 0% of the other 871 servers in this category
  • Published to the registry more recently than 71% of the other 871 servers in this category
  • Basic checks equal to or better than 100% of the other 871 servers in this category

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is Genefoundry safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.10.10) reached the registry 10 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

genefoundry-router

A thin FastMCP 3.x aggregator that federates the GeneFoundry *-link MCP fleet behind a single Streamable-HTTP endpoint. A host adds one server — genefoundry — and gets every biomedical backend with collision-free _ naming and search-based discovery.

[!IMPORTANT]

Research use only. Not clinical decision support. Do not use for diagnosis,

treatment, triage, or patient management.

Why

An MCP host that mounted all 21 backends directly would face a wall of several hundred tools — more than a model can reason over, and a guarantee of name collisions. The router collapses that into one endpoint and replaces the flat catalog with a search surface, so a model finds the right tool by intent instead of by scrolling.

It is a *client* to each backend and a *server* to hosts: it namespaces and shapes the surface, but never rewrites a backend's data. The caller's token is never forwarded upstream.

Quick start

The fleet is hosted — no install required:

claude mcp add --transport http genefoundry https://genefoundry.org/mcp

Health check: genefoundry.org/health.

To run your own against the live fleet (Python 3.14+, uv):

uv sync --group dev

cp .env.example .env # set GF_*_URL backend URLs and GF_AUTH_MODE uv run genefoundry-router run --host 127.0.0.1 --port 8000 curl -s localhost:8000/health | python -m json.tool

An offline fake fleet (make dev-fleet + make run-dev, or one-shot make test-e2e) runs the real router against impersonated backends over real Streamable-HTTP — no Docker, no network.

Tools

The router does not surface the federated catalog flat. A model sees three things:

ToolPurpose
search_toolsRelevance search over the entire federated catalog
call_toolInvoke a hit by its _ name
*pinned entry points*Each backend's front-door tool, always visible — declared per-backend as entrypoints: in servers.yaml
search_tools(query="splicing prediction")   # → spliceai_predict_splicing (+ schema)

call_tool(name="spliceai_predict_splicing", arguments={...})

Pinning makes each domain's canonical tool reachable deterministically rather than by relevance luck. See How discovery works — including the two traps that bite MCP clients.

Federated backends

22 backends, 285 tools, each surfaced namespaced — e.g. gnomad_search_genes.

Data & provenance

The router serves no data of its own; each backend owns its sources, licences and citation guidance, and the router mirrors their disclaimers.

What it does own is integrity of the tool surface. A backend can serve a clean tool at review time and later change its definition — the channel for a rug pull. The router fingerprints every normalized tool definition and diffs the live fleet against a reviewed, packaged baseline (genefoundry_router/data/fleet-baseline.json), enforced at startup and on a schedule. See Deployment → drift detection.

Documentation

  • Configuration & authentication — every GF_* variable, the OAuth/JWT resource-server modes, and the startup guards.
  • Deployment — container release, digest pinning, rollback, and drift detection.
  • How discovery works — the search surface, entry-point pinning, and how discoverability is measured.
  • Design spec — the architecture and why it is shaped this way.
  • Fleet standards — Tool-Naming · Response-Envelope · MCP-Behaviour · Tool-Surface-Budget · Tool-Schema-Documentation · Container-Hardening · Versioning · README.
