What is the UniProt MCP Server?
Connect your AI agent to UniProt — the Universal Protein Resource — the world's definitive knowledge base for protein sequence and functional information.
What you can do
- Protein Search — Find proteins by name, gene symbol, function, or organism across 250M+ entries from both TrEMBL (auto-annotated) and Swiss-Prot (manually curated)
- Accession Lookup — Get complete protein data by UniProt accession number (e.g., P04637 for human p53) including function, subcellular location, and full amino acid sequence
- Gene Search — Find all proteins encoded by a specific gene name across multiple organisms to compare orthologs and paralogs
How it works
- Subscribe to this server
- Start searching proteins immediately — no API key required
Who is this for?
- Molecular Biologists — quickly look up protein functions, domains, and post-translational modifications for experimental design
- Bioinformaticians — retrieve protein sequences and annotations programmatically for large-scale comparative analyses
- Drug Discovery Teams — identify therapeutic targets by searching protein functions and disease associations
Built-in capabilities (3)
Get full protein details by UniProt accession ID
Returns protein name, gene, organism, function, subcellular location, and sequence. Try: insulin, hemoglobin, p53, BRCA1, spike protein. Search UniProt for proteins by name, function, or keyword
Returns all protein isoforms and their functional annotations. Find proteins encoded by a specific gene
Why LangChain?
LangChain's ecosystem of 500+ components combines seamlessly with UniProt through native MCP adapters. Connect 3 tools via Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures. with LangSmith tracing giving full visibility into every tool call, latency, and token cost.

Frequently asked questions
What is the difference between Swiss-Prot and TrEMBL entries?
Swiss-Prot contains 570K+ entries that have been manually reviewed and curated by expert biologists — the gold standard for protein annotation. TrEMBL contains 250M+ entries that are computationally annotated from gene sequences. Swiss-Prot entries are marked as 'reviewed' and are highly reliable; TrEMBL entries are automatically generated and may contain errors.
Do I need to register or pay for an API key?
No. UniProt REST API is completely free and open without any authentication. There are no rate limits for reasonable usage patterns. UniProt is funded by the National Institutes of Health (NIH), European Molecular Biology Laboratory (EMBL), and the Swiss Institute of Bioinformatics (SIB).
Can I retrieve full amino acid sequences for proteins?
Yes. Every protein entry includes the full amino acid sequence with length information. The sequence is returned in standard one-letter amino acid code. For very large proteins (10,000+ residues), the sequence may be truncated in the response but the full accession data is always provided for direct download.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
