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.

A futuristic MCP client docking bay
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.

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

CrossRef 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.

Preview access · not provider authentication

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

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

    The MCP provides access to over 150 million DOI-registered works.

  • 02

    Can I find preprints?

    Yes, the capability can search preprints registered on servers like bioRxiv, medRxiv, and SSRN.

  • 03

    How do I find works by a specific researcher?

    You can use the search_by_orcid capability to find a complete publication record using their ORCID identifier.

  • 04

    Does this work with any AI client?

    Yes, it works with any MCP-compatible client like Claude, Cursor, Windsurf, or VS Code.

  • 05

    Can I check if a DOI is real?

    Yes, the validate_doi capability checks if a DOI is valid and registered in the CrossRef system.

  • 06

    Do I need an API key?

    No. The CrossRef API is fully public. Including a mailto address gets you into the "polite pool" with higher rate limits, which this server handles automatically.

  • 07

    What is a DOI?

    A Digital Object Identifier (DOI) is a unique, permanent identifier assigned to academic publications, datasets, and other research outputs. Format: "10.1038/s41586-021-03819-2". CrossRef is the largest DOI registration agency with over 150 million registered DOIs.

  • 08

    Can I search by ORCID?

    Yes. You can look up all works associated with a researcher's ORCID identifier. ORCID provides a unique, persistent identifier for researchers. similar to what DOI does for publications.
