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

Frontend Development

Mock a REST API to build out a dashboard before the actual backend is even written.

02

Webhook Debugging

Intercept incoming calls from third-party services to see exactly what data they are sending.

03

Edge Case Testing

Force an endpoint to return a 500 error or a slow response to see how your app handles it.

04

Integration Testing

Use OpenAPI specs to quickly spin up a complete mock environment for a new service.

Automate a task

Put Beeceptor 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

Beeceptor 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 Beeceptor 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. 29 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 Beeceptor, so you can see the experience inside your AI.

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

This MCP is built for engineers who need to isolate their work from unstable or unfinished backend services.

  • 01

    Frontend Developers

    They tell the agent to mock backend dependencies so they can build UI without a live API.

  • 02

    QA Engineers

    They instruct the agent to simulate error codes and timeouts to test app resilience.

  • 03

    Backend Developers

    They use the agent to inspect third-party webhook payloads in real time.

FAQ

Questions Beeceptor owners ask.

  • 01

    How do I use Beeceptor with Claude?

    Once you connect the Beeceptor MCP via Vinkius, you can simply ask Claude to create mock rules or check request history using natural language.

  • 02

    Can I mock an entire API using a Swagger file?

    Yes, you can tell your agent to use the upload_spec capability to upload your OpenAPI or Swagger specification, which will generate the endpoints automatically.

  • 03

    How do I see the data sent to my webhooks?

    You can ask your agent to list or get requests to see the payloads and headers of incoming traffic in real time.

  • 04

    Does this MCP handle authentication?

    Yes, you can use the update_settings capability to configure authentication and CORS for your subdomains.

  • 05

    Can I simulate a stateful API?

    Yes, the MCP includes capabilities like upsert_state and get_state_item to maintain data across different API calls.

  • 06

    Can I enable CORS for my mock endpoint through the AI?

    Yes. You can use the update_settings capability to toggle CORS, request logging, and other endpoint features instantly.

  • 07

    How do I see the payloads of recent requests sent to my Beeceptor subdomain?

    Use the list_requests capability. It retrieves a list of recent incoming HTTP calls, allowing your agent to analyze headers and body content.

  • 08

    Is it possible to simulate a database or state between API calls?

    Yes, Beeceptor provides a key-value store. You can use upsert_state to save data and get_state_item to retrieve it in subsequent mock responses.
