CAUTION· not started

Publisher claims: "Production-grade MCP server for KiCad EDA—PCB design, DRC, simulation, BOM, DFM, and manufacturing." Observed in sandbox: no network, touches nothing outside the project, writes no memory.

Coverage

Not started: dependency install failed; the server itself was not observed.
Tested
the dependency install step · every file read, file written and host contacted by what ran
Not tested
server startup · the tool list · tool behavior

What this means for the label: Caution here covers what ran. The server's tools were not exercised with a real credential, so nothing about their behavior is asserted; the credential summary below says what to do with that.

Before you give it your token

It will ask for
KICAD_API_TOKENKICAD_MCP_AUTH_TOKENConfiguration, not credentials: KICAD_API_SOCKET, KICAD_MCP_DESKTOP_UV, KICAD_MCP_ENABLE_EXPERIMENTAL_TOOLS, KICAD_MCP_HOST, KICAD_MCP_LOCALE, KICAD_MCP_LOG_LEVEL, KICAD_MCP_OPENCODE_CONFIG_VERSION, KICAD_MCP_OPERATING_MODE, KICAD_MCP_PORT, KICAD_MCP_PROJECT_DIR, KICAD_MCP_TELEMETRY_ENABLED, KICAD_MCP_TIMEOUT_MS, KICAD_MCP_TRANSPORT, KICAD_MCP_URL, UV_TOOL_DIR
Where it talks to
no vendor host named in the codeAlso kicad.org, astral.sh, inspect.ai, buymeacoffee.com, oaslananka.dev — not the publisher's domain; check what for before connecting.
What the honeypot saw
no credential files read · no network
What we could not test
server startup · the tool list · tool behavior

Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names kicad.org, astral.sh, inspect.ai, buymeacoffee.com, oaslananka.dev as well as its own vendor. The guard injects KICAD_API_TOKEN, KICAD_MCP_AUTH_TOKEN only into requests to the host you bind (and its subdomains) and refuses the rest.

Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios; not started: dependency install failed; the server itself was not observed) on 2026-11-15 and scored it 78/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Access to sensitive file paths; Access to sensitive file paths; Access to sensitive file paths. Summary: no network, touches nothing outside the project, writes no memory.
