Linked life-science search: 43M+ papers, 1.2M+ trials, drugs, genes, FDA/EMA approvals, patents.
Overview
Hosted life-science research MCP server that lets an assistant search and cross-link publications, clinical trials, drugs, genes, approvals and patents.
- What you can do
- Search and retrieve biomedical publications, with abstracts, authors, citations, MeSH terms and optional fulltext
- Search and retrieve clinical trials with phase, status, sponsors, interventions, endpoints and posted results
- Search and retrieve harmonized drugs and genes, including structures, clinical stage, biotype and protein annotations
- Search FDA and EMA authorizations and read parsed source-document sections such as labels and reviews
- Search life-science patents (preview) and report data issues to the Amass data team
- Filter results by date ranges, last-update and create dates, journals or publication types, with a limit of 1 to 50
- When to use it
- Useful when you need evidence from the biomedical literature, trial registries, drug and gene records, regulatory approvals or patents, and want to move between them in one query. Also suited to tracking what changed in a research area since a given date.
- Requirements
- A remote streamable HTTP endpoint; nothing to install locally. OAuth 2.1 sign-in with an Amass account is required, and new accounts get trial credits. Clients that cannot complete OAuth can send an Amass API key as a bearer token. Network access to the hosted service.
Installation
In SourceWeft
- Open Amass in the dashboard and add it to a workspace.
- Connect the required credentials. They are stored privately and never shown on public pages.
- Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/tech.amass%2Famass/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Other MCP clients
Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

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:
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.
The server supports every MCP protocol revision from 2024-10-07 through
2026-07-28. Clients on 2026-07-28 are served per request, with no initialize
handshake or session; the tools are identical on every revision.
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 search_amass_<core>_records tool for discovery and a
get_amass_<core>_record tool for fetching a known identifier. RegulatoryCore
adds get_amass_regulatorycore_document_section for full source-document text,
and send_feedback reports data issues straight to the Amass data team.
Every search tool takes a limit (1–50, default 10). Every search except
PatentCore also takes minLastUpdateDate and minCreateDate, which filter on
when Amass last updated a record or first ingested it. Use them for "what
changed since I last looked" questions. Publication, patent, trial start and
trial completion dates can be bounded on both ends, and BioMedCore search can be
narrowed to given journals (journalIssns) or publication types
(publicationTypes, e.g. Clinical Trial or Conference). Every record
carries a url that links to its source.

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
Each ## vN entry in the MCP changelog
becomes listing version N.0.0, but only once the server is actually deployed.
Check that the new parameters appear in the live tool schemas before bumping.
-
On a
release-Nbranch, bumpversioninserver.json. Update the README's "What you get" for anything user-facing in the changelog entry, and updatedescriptionif a headline count moved. -
Open a PR — CI validates the file, checks the version is not already published, and confirms
https://mcp.amass.tech/mcpis up. -
Merge, then tag:
-
A second admin approves the
mcp-registrydeployment on the tag's Actions run. Publishing waits there until they do. -
Create the GitHub Release and point back to the changelog:
-
Delete the local
release-Nbranch. GitHub drops the remote one on merge.
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
Generates the keypair and prints the Cloudflare TXT record and the
gh secret set command for MCP_PRIVATE_KEY. Follow its four steps, then
delete the local key.pem.
Publishing by hand
Verify:
Constraints worth remembering
descriptionis capped at 100 characters. CI enforces this.- Published versions are immutable, and servers currently cannot be deleted or unpublished — corrections ship as a new version.
- Do not name a release branch after its version; it collides with the tag and
git push origin vX.Y.Zbecomes ambiguous.

85% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
