# Amass

A hosted MCP server that links six life-science datasets: papers, clinical trials, drugs, genes, regulator approvals and patents. Useful when the agent should cite sources instead of guessing.

## What it does

Amass runs as a hosted service. The repository only carries the MCP Registry entry, so there is nothing to build or run locally. Clients connect over streamable HTTP with OAuth 2.1 by pointing at `https://mcp.amass.tech/mcp`; you get sent to an Amass sign-in, and a fresh account comes with trial credits. If a client cannot finish an OAuth flow, it can pass an Amass API key (`amass_…`) as a bearer token instead.

Six Cores sit behind the endpoint, cross-linked so one query can hop between them. BioMedCore holds biomedical publications with abstracts, authors, journal metadata, citations and MeSH terms, plus society conference abstracts. TrialCore covers clinical trials with phase, status, sponsor, conditions, arms and posted results. DrugCore carries harmonized molecules, GeneCore genes with UniProt annotations, RegulatoryCore FDA and EMA authorizations with parsed source documents, and PatentCore is in preview.

Each Core exposes a `search_amass_<core>_records` tool for discovery and a `get_amass_<core>_record` tool for pulling a known identifier. Searches take a `limit` between 1 and 50, defaulting to 10. Every Core except PatentCore also accepts `minLastUpdateDate` and `minCreateDate`, which filter on when a record was last touched or first ingested — handy for "what changed since I last looked".

## Requirements
- Remote server: `https://mcp.amass.tech/mcp`

## Install

### Claude Code (native platform)

**Platform CLI: remote server**
```bash
claude mcp add --transport http amass https://mcp.amass.tech/mcp
```

### Codex

**Platform CLI: remote server**
```bash
codex mcp add amass --url https://mcp.amass.tech/mcp
```

### Cursor

**Config file**
File `.cursor/mcp.json`:
```json
{
    "mcpServers": {
        "amass": {
            "url": "https://mcp.amass.tech/mcp"
        }
    }
}
```

### GitHub Copilot

**Config file**
File `.vscode/mcp.json`:
```json
{
    "servers": {
        "amass": {
            "type": "http",
            "url": "https://mcp.amass.tech/mcp"
        }
    }
}
```

### Gemini CLI

**Platform CLI: remote server**
```bash
gemini mcp add -t http amass https://mcp.amass.tech/mcp
```

## When to use it
- pull papers tied to a given gene or drug
- check which phase a trial stopped at
- compare FDA and EMA authorizations for one molecule
- see what entered the corpus since the last query
- trace a topic from a paper through to a patent

## Example prompts
- Search Amass for clinical trials on this drug and show phase and status
- Which publications for this gene were updated in the past month?
- Show FDA and EMA approvals for this compound
