What your agent gets (and you stop paying for in lab time)

Hardware-Free Simulation

Flash firmware ELFs onto virtual ARM Cortex-M4 and RISC-V targets in milliseconds. Test embedded code without wiring, debugging probes, or physical hardware constraints.

Bit-Identical Determinism

Eliminate intermittent heisenbugs. VirtMCU ensures bit-identical execution runs by locking virtual time and scheduling event logs deterministically.

Multi-Node Network Topologies

Simulate complex environments with virtual UART, CAN, and 802.15.4 links. Test cross-vendor interoperability (e.g. ST <-> NXP) in isolated networks.

Deep Introspection & Telemetry

Access registers, physical guest memory, serial console streams, and link frames programmatically. Debug without JTAG probes or printf overhead.

On-Demand Parallelism

Spin up isolated simulation sessions for CI/CD test swarms and destroy them in a single API call. Run up to 10 concurrent sessions per developer account.

Native AI Agent Integration

MCP-native out of the box. Autonomous agents discover available registers and link tools dynamically via standard Model Context Protocol endpoints.

FAQ

Do I need hardware?

No. Everything runs on virtual microcontrollers with deterministic virtual time. Nothing to wire, nothing to brick.

How does my agent connect?

Over MCP (Streamable HTTP). Your agent creates a session via the REST API and discovers all tools via tools/list. See /docs.

How are API keys stored?

We store only the SHA-256 hash of your key. The raw key is shown exactly once, to you.
