UniProt

You have access to a full-featured UniProt MCP Server that provides 26 specialized tools to query UniProt data, analyze protein sequences and features, explore pathways and interactions, and export data. This server is designed for AI assistants and MCP clients to perform advanced protein research directly against UniProt’s REST API, enabling efficient, integrated bioinformatics workflows.

How to use

You interact with the UniProt MCP Server through an MCP client. Start by starting the server in your environment or container, then configure your MCP client to connect to the server. Use the tools to search proteins, retrieve detailed information, fetch sequences, analyze features, explore homologs and orthologs, inspect structures, assess variants, and perform batch and advanced searches. You can also retrieve literature references, external database links, and taxonomy information, and export data in multiple formats. The server handles input validation, API errors, and timeouts, and provides clear results or graceful degradation when partial data is available.

How to install

# Prerequisites
- Node.js (v16 or higher)
- npm or yarn

# Clone the project
git clone <repository-url>
cd uniprot-server

# Install dependencies
npm install

# Build the project
npm run build

# Start the server (stdio MCP server)
npm start

Additional notes and configuration

The server can run in a Docker container or as a local stdio process. See the following common deployment patterns for MCP client integrations.

For container-based usage, you can run the server with Docker and connect clients via stdio to the container. You may also set up a Docker Compose service for easier management.
