Amass MCP server

Amass MCP server

Amass is a remote MCP server for life-science research. It exposes one linked corpus — publications, clinical trials, drugs, genes, regulatory approvals and patents — to Claude, ChatGPT, VS Code, Cursor and any other MCP client.

This repository holds the MCP Registry listing (server.json). The server itself is a hosted service, so there is nothing here to install or run.

Connect

Amass speaks streamable HTTP with OAuth 2.1. Most clients need only the URL:

https://mcp.amass.tech/mcp

You will be redirected to sign in with your Amass account; new accounts are provisioned automatically with trial credits. Clients that cannot complete an OAuth flow can instead send an Amass API key (amass_…) as a bearer token.

Or install it from the registry by name: tech.amass/amass.

What you get

Six Cores, cross-linked so you can move between them in a single query — publications ↔ trials, trials ↔ drugs, drugs ↔ genes, drugs ↔ approvals, and patents ↔ drugs/publications.

Each Core has a searchamassrecords tool for discovery and a getamassrecord tool for fetching a known identifier. RegulatoryCore adds getamassregulatorycoredocumentsection for full source-document text, and send_feedback reports data issues straight to the Amass data team.

Maintainers

Everything below is the release runbook for this listing. It is not needed to use the server.

server.json is the source of truth. The registry authenticates by DNS: a TXT record on amass.tech carries the public half of an Ed25519 key, and CI signs with the private half. That is why the listing is namespaced tech.amass/… rather than under a GitHub org.

Publishing a new version

published, and confirms https://mcp.amass.tech/mcp is up.

1. Edit server.json and bump version.
2. Open a PR — CI validates the file, checks the version is not already

1. Merge, then tag:

git tag vX.Y.Z && git push origin vX.Y.Z    # must match "version" in server.json

The tag must match version in server.json or the workflow fails.

The listing version tracks the major version of the deployed MCP server.

One-time DNS auth setup

./scripts/setup-dns-auth.sh

Generates the keypair and prints the Cloudflare TXT record and the gh secret set command for MCPPRIVATEKEY. Follow its four steps, then delete the local key.pem.

Publishing by hand

brew install mcp-publisher
mcp-publisher login dns --domain amass.tech \
  --private-key "$(openssl pkey -in key.pem -noout -text | grep -A3 'priv:' | tail -n +2 | tr -d ' :\n')"
mcp-publisher publish
