Why investors use MCP

Three things you get that you don't from web search.

Higher signal than web search for deal research.

Date, journal quality, retraction status, trial phase — structured filters surface the evidence your therapeutic area needs, not whatever ranks on Google.

Agentic, not one-shot.

The assistant chains searches automatically — broad pipeline scan, filter to active trials, drill into a specific asset — without you driving each step.

Every claim citable to source.

Every result links directly to its underlying record. Take findings to the investment committee with confidence — trace any claim in a single click.

How it works

Connect your AI assistant to the full Amass corpus.

Connect Amass MCP from Claude or ChatGPT and sign in once with your Amass plan. The assistant then queries 40M+ papers, 575K+ trials, and 170M+ patents on your behalf — nothing else to configure. Same access your plan gives you, inside the assistant you already use.

The skill

Add the Evidence Scout skill — structured guidance for deal-quality research.

The skill teaches the assistant how to use Amass for investor and BD workflows — when to filter by journal quality, how to structure landscape scans, when to drill into a specific trial or target. Works in any assistant that supports the open SKILL.md format: Claude, Codex, GitHub Copilot, Gemini CLI.

How do I install the skill file?

Double-click the .skill file on Mac to install it into Claude. For other tools, unzip the .zipinto the tool's skills directory:

  • Claude Code: ~/.claude/skills/
  • Codex: ~/.codex/skills/
  • Gemini CLI: ~/.gemini/skills/

Try it

Once it's connected, start asking.

Switch between baseline pipeline queries the connector handles well, and the deeper assessments the skill is built to make easier.

FAQ

Honest answers.

Is this suitable for investment due diligence and BD?

Yes — that's the primary use case for this page. VC analysts and BD leads use Amass to run pipeline scans, target assessments, competitive landscapes, and FTO analyses directly in their AI assistant. Every output is cited to primary source, so findings can go into IC decks or deal memos without a separate verification step.

Which assistants is the Amass MCP available in?

Claude (Pro/Max/Team/Enterprise), ChatGPT (Plus/Business/Enterprise/Edu), Claude Code, Codex CLI. Microsoft 365 Copilot via enterprise deployment. Perplexity, Gemini CLI, and other MCP-compatible clients should also work — let us know if you try one of these.

Is the connector approved by Anthropic, OpenAI, or others?

Amass MCP is listed in the ChatGPT app store — one-click install from inside ChatGPT. Directory listings in Claude and other assistants are still in progress; for now those install as custom connectors, which works the same way functionally.

Do I need an API key?

No. The MCP authenticates via your existing Amass plan. You'll sign in once when you connect.

Does this work on ChatGPT Plus?

Yes. Amass MCP is available on ChatGPT Plus, Business, Enterprise, and Edu — install in one click from the ChatGPT app store. If your tenant restricts third-party app installs, a developer-mode fallback is available on the install page.

What data does Amass have access to?

Only the queries the assistant sends and the responses we return. The assistant runs on your provider's infrastructure, not ours.

My company uses Microsoft 365 — what are my options?

We can ship a declarative agent backed by the same Amass MCP for sideload by your IT admin. See the Enterprise section above and get in touch.
