> Use Synthesize Bio MCP to run gene expression analyses from natural-language prompts with the Synthesize Bio Claude Connector.

# Synthesize Bio MCP

Synthesize Bio MCP is a connection that lets AI tools like Claude use Synthesize Bio directly inside a chat. It can start and monitor gene expression analyses from a natural-language request.

Use this guide to:

* Set up the Claude Connector
* Understand what kinds of analyses it supports
* Write better prompts
* Troubleshoot sign-in or long-running jobs

## Server URL

```text theme={null}
https://app.synthesize.bio/api/mcp
```

## What you can do with it

* Compare gene expression between two sample groups such as heart vs liver or tumor vs normal tissue.
* Run analyses in bulk or single-cell mode.
* Let your AI assistant wait on the long-running workflow and return the completed report when it is ready.

## Before you begin

* You need a Synthesize Bio account on [app.synthesize.bio](https://app.synthesize.bio).
* You need access to Claude connectors.
* The Synthesize Bio Claude Connector uses OAuth to authenticate your account to the MCP.
* Most analyses take several minutes to complete, so expect an asynchronous workflow rather than an instant result.
