lava-mcp

An MCP server that exposes a LAVA instance to agents (and humans) — letting them query the board farm, submit and manage test jobs, open interactive sessions to a board, reach a board's serial console, serve build artifacts to jobs, and read the deployed LAVA's own docs and source.

It is a thin client over LAVA's REST API (v0.2/v0.3); point it at any LAVA instance.

Quick start

pip install -e .[dev]

export LAVA_URL=https://lava.example.com
export LAVA_TOKEN=<your-api-token>
lava-mcp                                  # stdio, for a local MCP client

For a hosted HTTPS deployment (required by the interactive, console and artifact features) and per-request token handling, see docs/deployment.md.

Features

Each feature is documented on its own page:

• LAVA jobs & inventory — the core proxy: query devices/jobs and run the standard deploy/boot/test job. Includes building jobs from templates, the "jobs are independent" rules, and searching jobs by metadata. Start here.

• Interactive board sessions — a shell in a container next to the board (flashing, fastboot/adb/qdl, bring-up) over an SSH gateway; run_in_session, attach_shell, and the device-command power/recovery relay.

• Serial console — the board's own UART via a ser2net proxy: boot/kernel logs and a live console, with or without a deploy+boot job.

• Artifact store — upload a build product the server hosts temporarily; LAVA (or a booted device / container) fetches it back, with the secret kept out of the job via LAVA remote-artifact tokens.

• LAVA docs & source mirror — read_lava_docs serves the deployed LAVA's documentation and source from a local git mirror at the exact deployed ref.

Supporting docs:

• Deployment & credentials — install, token handling, stdio vs hosted, docker compose + Caddy.

• Configuration reference — every environment variable and CLI flag.

• Security model — gateway trust model, enforced controls, and operator responsibilities.

• Roadmap — design notes and future work.
