Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Curated set · 3 capabilities

We ship only the actions that matter.

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through UniProt.

  1. 01

    Search uniprot gene

    This capability finds all protein isoforms and their functional annotations for a specific gene. It is useful for identifying every protein encoded by a target gene.

  2. 02

    Get uniprot protein

    This capability retrieves complete protein details using a UniProt accession ID. It provides full functional data and sequences for a specific entry.

  3. 03

    Search uniprot

    This capability searches the UniProt database using protein names, functions, or keywords. It returns essential data like organism, subcellular location, and sequence.

Real work

What teams actually run

01

Target Identification

A researcher asks the AI to find proteins associated with specific diseases to identify new drug targets.

02

Comparative Genomics

A bioinformatician uses the gene search capability to compare protein isoforms across different species.

03

Sequence Analysis

An engineer pulls specific amino acid sequences to use in downstream computational modeling.

04

Functional Mapping

A scientist queries subcellular locations to understand where a protein operates within a cell.

Automate a task

Put UniProt to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

UniProt works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put UniProt to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Connect your client

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 3 capabilities arrive ready to run.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of UniProt, so you can see the experience inside your AI.

It does not authenticate your account with UniProt. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

Who it's for

Built for the work UniProt owners hand off.

This MCP is built for professionals working in life sciences and computational biology who need to feed biological data into their AI workflows.

  • 01

    Molecular Biologists

    They use the AI to quickly look up protein functions and post-translational modifications for experimental design.

  • 02

    Bioinformaticians

    They hand off the task of retrieving protein sequences and annotations for large-scale comparative analyses to their agent.

  • 03

    Drug Discovery Teams

    They use the AI to identify potential therapeutic targets by searching protein functions and disease associations.

FAQ

Questions UniProt owners ask.

  • 01

    Do I need an API key to use this UniProt MCP?

    No. Vinkius hosts the connection, so you can start searching proteins immediately without managing your own API credentials.

  • 02

    Which AI clients can use this connector?

    Any MCP-compatible client works, including Claude, Cursor, Windsurf, and VS Code.

  • 03

    Does this include manually curated data?

    Yes. The MCP provides access to both the manually curated Swiss-Prot entries and the auto-annotated TrEMBL entries.

  • 04

    Can I search for proteins by gene name?

    Yes. You can use the gene search capability to find all proteins encoded by a specific gene across multiple organisms.

  • 05

    How many protein entries are available?

    The MCP provides access to over 250 million protein sequences and functional annotations.

  • 06

    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.

  • 07

    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).

  • 08

    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.
