What is easyeda-copilot-mcp?

A guide for using EasyEDA Copilot MCP tools to design electronic circuits and circuit boards. EasyEDA is software for creating schematics and printed circuit boards, while MCP connects those tools to an assistant.

Creating or modifying schematics, placing PCB components, preparing assemblies, previewing boards, checking design-rule violations, and routing boards.

It helps follow the required rules for component placement, board checks, previews, assembly, and routing without relying on undocumented tool behavior.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00046	$0.00326
Opus 5	$0.00023	$0.00163
Sonnet 5	$0.00009	$0.00065
Haiku 4.5	$0.00005	$0.00033

Security

Grade A, and why

easyeda-copilot-mcp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (pcb-layout/dsl.ts, pcb-layout/examples/ELRS/ELRS.js, pcb-layout/examples/ESpower/ESpower.js, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

EasyEDA Copilot MCP

Use this skill when an EasyEDA Copilot MCP server provides EasyEDA schematic and PCB tools.

The local files in this directory are the documentation source for MCP work. Do not fetch server prompt endpoints for MCP context. Read only the docs needed for the task.

PCB Contract

make_pcb_layout creates placement only: outline, mechanical objects, components, synthetic pads, holes, and designator positions. It does not route tracks, create copper pours, or configure DRC. Read pcb-layout/mcp-workflow.md before calling it.

Files

What ships with it

13 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

easyeda-copilot-mcp is a skill published in the GitHub repository biosshot/easyeda-copilot (118 stars, last pushed 2d ago), licensed MIT. It adds 46 tokens to every session and 326 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
