copper-pilot-cli 0.1.6

CopperPilot in your terminal: a thin, open-source client for CopperPilot electronics design agent, the best AI for PCB Design.

Prerequisites

• Python 3.12 or newer
• A CopperPilot account for login
• KiCad 10 on PATH only if you run examples/001_esp32

Install and run

pip install copper-pilot-cli
copper-pilot

The first interactive launch opens a browser for CopperPilot device login. With no path argument, the current directory is the workspace and a new chat starts immediately. Any existing directory is valid.

copper-pilot ./my-board
copper-pilot --resume
copper-pilot threads list
copper-pilot -n -m "Review this board" --json

Both copper-pilot and copper-pilot-cli run the same program. copper-pilot --help lists flags; docs/cli.md is the full command reference.

Use from Claude Code, Cursor, or Codex

CopperPilot stays the electronics agent. Copy skills/copper-pilot-review/SKILL.md into your harness, or expose the same agent over MCP:

claude mcp add copper-pilot -- copper-pilot mcp

Claude Code can also install the in-repo plugin:

/plugin marketplace add CopperPilot/copper-pilot-cli
/plugin install copper-pilot

That plugin starts copper-pilot mcp and adds @copper-pilot plus /copper-pilot-review. Setup for Cursor, Codex, and approvals: docs/harness.md.

Configuration

• Production API: https://copperpilot.ai
• Development override: COPPER_PILOT_API_URL
• User state: ~/.copper-pilot/.state
• Project artifacts: .copperpilot/

Credentials are stored in a private, atomically replaced auth.json; on POSIX the parent directory is mode 0700 and the file is mode 0600.

LangChain

from copper_pilot_cli.copper_protocol import CopperMode
from copper_pilot_cli.langchain import CopperPilotAgent
from helper import drc_violations, erc_errors, render_pcb, run

PLAN = CopperMode.PLAN

copper_pilot = CopperPilotAgent(workspace="esp32")

run(copper_pilot, "Build me an ESP32 dev board.", PLAN)
run(copper_pilot, "Let us build this plan.")
run(copper_pilot, "Inspect the PCB, check for any missing 3D models, and apply them accordingly.")

assert erc_errors() == 0
assert drc_violations() == 0
render_pcb("esp32.png")

CopperPilotAgent is a Runnable, not a chat model. It represents a complete hosted agent run, including local tool requests. Use as_langgraph() for graph composition or as_compiled_subagent() for explicit delegation from an outer Deep Agent. The compatible deepagents runtime is installed and pinned by this package.

That snippet is the runnable example in examples/001_esp32.

Security boundary

The hosted agent may request local filesystem and shell tools. Reads and searches run freely. Writes, edits, deletes, and shell commands are gated by Manual approval by default. Auto permits only deterministic routine actions; unknown actions still ask. YOLO must be selected explicitly.

Filesystem, search, edit, and shell execution use Deep Agents' native FilesystemMiddleware tools and LocalShellBackend; CopperPilot's adapter only normalizes hosted tool names, approval decisions, and result envelopes.

Computer use, model/provider selection, local model execution, LangSmith tracing, content telemetry, MCP host/plugin-runtime controls, and server implementation code are not part of this package. A thin MCP server (copper-pilot mcp) that delegates to the hosted agent is.

See UPSTREAM.md and NOTICE for the retained Textual client attribution.

Development

pip install -e ".[dev]"
make fmt
make lint
make test

make test runs pytest -m "not live". Live tests skip unless a CopperPilot credential is stored. Release tagging is make release. Details: docs/development.md.
