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.

Real work

What teams actually run

01

Pre-Deployment Check

A developer needs to confirm that a new API version is stable. They use the MCP to create a deployment and immediately run a full test suite.

02

Schema Compliance Check

You receive a data payload and need to know if it matches the required structure. You use validate_json to confirm schema compliance instantly.

03

Quick Health Check

Before calling a service, you just need to know if it's up. You retrieve a service status badge instead of running a full test.

04

Documentation Drift

The API changed, but the tests haven't. You use sync_specification to pull the latest OpenAPI files and update your test definitions.

Automate a task

Put Assertible 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

Assertible 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 Assertible 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. 7 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 Assertible, so you can see the experience inside your AI.

It does not authenticate your account with Assertible. 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 Assertible owners hand off.

This MCP is essential for teams that need to maintain high API quality. DevOps engineers use it to automate deployment tracking, QA engineers use it to verify API health without leaving their chat client, and backend developers use it to validate data schemas immediately after code changes.

  • 01

    DevOps Engineers

    Automate deployment tracking and trigger post-deploy test runs directly from your chat or CLI.

  • 02

    QA Engineers

    Run specific test suites and verify API health quickly, keeping your workflow contained.

  • 03

    Backend Developers

    Validate JSON schemas and sync API specifications as soon as you make code changes.

FAQ

Questions Assertible owners ask.

  • 01

    Do I need to use a specific AI model to connect this MCP?

    No. You connect this MCP using any MCP-compatible client, including Claude, Cursor, Windsurf, or VS Code. The MCP handles the connection, not the underlying AI model.

  • 02

    What kind of APIs does this MCP support?

    It supports any API that uses OpenAPI, Swagger, or Postman specifications for defining its structure. The capabilities are designed to manage the lifecycle of those specifications.

  • 03

    Can I run tests on a specific endpoint only?

    Yes. If you know the exact test ID, you can use the run_specific_test capability. This is faster than running the entire service suite.

  • 04

    Is this just for testing, or can it help with data validation too?

    It does both. Beyond testing, you can use the validate_json capability to check if arbitrary JSON documents conform to a specific schema draft.

  • 05

    Can I trigger a full test suite run after a new deployment?

    Yes. Use the create_deployment capability. It tracks the deployment to your environment and automatically triggers the associated test runs for that service.

  • 06

    How do I keep my tests in sync with my OpenAPI documentation?

    You can use the sync_specification capability with your Import ID. This ensures your Assertible tests stay up-to-date with any changes in your Swagger or OpenAPI files.

  • 07

    Is it possible to check the current status of a service for a README file?

    Absolutely. Use get_service_status_badge to retrieve the markdown and URL for a status badge, which you can then embed directly into your documentation.
