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 · 4 capabilities

We ship only the actions that matter.

Capability set01 / 01

01-04

4 capabilities in this set.

Part of 4 available through Protein Molecular Weight Calculator.

  1. 01

    Calculate composition mass

    This capability calculates total molecular weight using only the counts of each amino acid present in a sample.

  2. 02

    Calculate sequence properties

    This capability generates a full suite of physical properties from a specific single-letter amino acid sequence.

  3. 03

    Estimate isoelectric point

    This capability finds the pH at which a protein sequence becomes electrically neutral.

  4. 04

    Get extinction coefficient

    This capability determines the UV absorption capability of a protein at the 280nm wavelength.

Real work

What teams actually run

01

Protein Concentration Prep

Use the extinction coefficient to figure out how much UV light a protein will absorb at 280nm.

02

Buffer Selection

Find the isoelectric point to choose the right pH for protein stability.

03

Sequence Validation

Check the molecular weight of a new sequence against expected experimental values.

04

Compositional Mass Checks

Calculate the weight of a protein based on its amino acid counts.

One connector, every AI

Protein Molecular Weight Calculator 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.

Connect your client

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 4 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 Protein Molecular Weight Calculator, so you can see the experience inside your AI.

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

FAQ

Questions Protein Molecular Weight Calculator owners ask.

  • 01

    How does this MCP handle post-translational modifications?

    The capabilities account for post-translational modifications to ensure the biochemical modeling remains accurate.

  • 02

    Can I use this with Cursor or VS Code?

    Yes, you can connect this MCP to any compatible client including Cursor, Windsurf, and VS Code.

  • 03

    What kind of sequences does it accept?

    It accepts single-letter amino acid sequences for full property calculations.

  • 04

    Does it calculate UV absorption?

    Yes, it can determine the extinction coefficient for UV absorption at 280nm.

  • 05

    Is it possible to calculate mass without a full sequence?

    Yes, you can use the composition mass capability if you only have the counts of specific amino acids.

  • 06

    How do I calculate the mass of a protein using a composition?

    You can use the calculate_composition_mass capability by providing a JSON mapping of amino acid single-letter codes to their respective counts.

  • 07

    Can I include post-translational modifications in the calculation?

    Yes, both calculate_sequence_properties and calculate_composition_mass accept an optional modifications parameter to account for added mass.

  • 08

    What is the purpose of the extinction coefficient capability?

    The get_extinction_coefficient capability determines the UV absorption capability of a protein at 280nm based on its aromatic amino acid content.
