How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security99
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- 32 of 144 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to biosshot/kicad-copilot). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 48 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability80
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 1671 tokens (~72/item across 23 items; 22 tools + 1 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management93
- Stability observed for 28 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage83
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 49% of tool parameters carry a description.Partial
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "clear_pcb_routing" implies "delete" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 23 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the KiCad Copilot MCP server?
KiCad Copilot runs locally as an npm package, launched with npx -y kicad-copilot-mcp. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

What is the KiCad Copilot MCP server?
KiCad Copilot is an MCP server listed in the public MCP registry as io.github.biosshot/kicad-copilot. File-oriented MCP server for KiCad schematics, PCB placement, routing, and pours. This page covers its npm package (kicad-copilot-mcp).
Is the KiCad Copilot MCP server safe to use?
KiCad Copilot scores 92 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 27 September 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the KiCad Copilot MCP server expose?
KiCad Copilot exposes 22 tools: component_search, search_reused_block, beautify_schematic, extract_circuit, get_schematic, and 17 more. Their descriptions and schemas cost roughly 1,646 tokens of context every time the server is loaded.
Is the KiCad Copilot MCP server still maintained?
KiCad Copilot is still listed as active in the MCP registry. We last reached this channel on 27 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the KiCad Copilot MCP server under?
KiCad Copilot declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
