Agent authored
Your agent supplies the structured specification. MBEstudio compiles and checks it without another model call.
Platform fee + compute
Read the specification schema ↗MBEstudio / Agent access
Engineering tools.
Your agent's workspace.
Turn a system specification into a SysML model, 3D geometry, evaluated requirements and simulation results. Connect your AI agent to MBEstudio over MCP, see the cost first, and pay only within the limit you set.
Review previewPaid agent access is not live. The planned Individual allowance is 2,000 credits per month. Stripe mappings, fees and hosting rates still need deployment verification. The existing studio remains available.
01 / Choose how to run
Three ways to cover the work.
Bring your own key
Use your provider key for the job. Your provider bills the model usage directly; MBEstudio charges for its tools and compute.
Platform fee + compute
The provider key is used in memory for that job and is never saved.
Managed
MBEstudio handles the model calls. Credits cover model usage at the configured markup, compute and the platform fee.
Model usage + platform fee + compute
Local GPU model execution will be available after the host's cost and resource limits are verified.
02 / Buy the capability you need
From specification to evaluated system.
Every paid job starts with a maximum reservation. Unused credits return to your balance after settlement.
| Tool | What you receive | Platform fee |
|---|---|---|
| Loading the shared pricing configuration... | ||
Compute rates are pending verification.
Describe, estimate, balance, job status, result retrieval and cancellation have no tool charge. Results belong to the connection or key that paid for the job. Canceling settles work already consumed and returns the unused reservation.
03 / Estimate, then run
Set the limit before work starts.
Ask your agent to show the estimate first. A job that exceeds your limit or balance is refused before model calls or paid compute start.
Long jobs return an ID immediately. Watch each generated section appear in your studio workspace, tagged via agent.

Use the tools where you already work.
Connection previewBrowser sign-in is being prepared for launch. These setup steps become available when the new gateway is deployed. Paid jobs remain disabled until rates and credit grants are confirmed.
Choose your app, add MBEstudio, and sign in with your account email. No API key needed.
1. Add MBEstudio to Codex
Run these commands in your terminal to add the server and sign in through your browser.
Codex setup
codex mcp add mbestudio --url https://studio.vectorstreamsystems.com/mcp
codex mcp login mbestudioUsing the desktop app? Add this remote MCP server in Codex settings, or use the CLI commands with the same local Codex configuration.
1. Add MBEstudio to Claude Code
Run this command. Then open Claude Code, run /mcp, and authenticate MBEstudio.
Claude Code setup
claude mcp add --transport http --scope user mbestudio https://studio.vectorstreamsystems.com/mcp1. Add MBEstudio to Cursor
Open the installer, confirm the server in Cursor, then connect.
Add to CursorYou can also add a remote MCP server in Cursor's personal MCP settings using the URL below. Restart Cursor if it does not appear.
1. Add MBEstudio to ChatGPT
Open Settings, then Apps. Enable developer mode where available and create a custom MCP app named MBEstudio. Paste the server URL below and select OAuth authentication.
Custom MCP apps must be enabled for your account or workspace. MBEstudio has not been published in the app directory.
1. Add MBEstudio to Claude Desktop
Open Settings, then Connectors. Add a custom connector named MBEstudio, paste the server URL below, and connect.
MCP server URL
https://studio.vectorstreamsystems.com/mcp2. Sign in and approve
Use your MBEstudio account email in the browser window. Review the app and return address, then choose Connect agent. You can disconnect it from your studio account at any time.
Connections can use prepaid credits within each job's spending limit. They cannot buy credits. Existing plans will receive agent credits only after their grants are confirmed.
3. Check the connection for free
Paste this message into your agent. It checks access without starting a paid job.
First message
Use MBEstudio's describe_mbestudio and get_credit_balance tools to confirm the connection. Do not start a paid job.Advanced: connect with an API key
For scripts or clients that require a bearer token, open your studio account and expand Advanced under Connect your agent. Create a named key, copy it once and keep it in your client's secret storage.
Authentication header
Authorization: Bearer YOUR_API_KEYFor BYOK jobs, configure X-Provider and X-Provider-Key as secret headers on a dedicated connection. Never put either API key in a prompt or committed configuration. Clients without custom secret headers can use agent-authored or managed mode.
Engineering scope
Traceable outputs, explicit limits.
Simulation executes declared state machines, timers, guards and event traces. Trade studies evaluate the model's stated objectives and constraints. Geometry supports envelopes and authored procedural bodies. STEP envelope export and NSGA-II trades exist in the studio but are not yet enabled through the bounded agent worker. No fluid solver, rigid-body solver or FMU execution is included.
Agent outputs include SysML, STL, scene JSON, engineering CSV and HTML reports. Availability is reported by the server before a job starts.
