What is electron-mcp CLAUDE.md?

A set of instructions for working on an Electron MCP server. Electron is a framework for building desktop apps with web technologies, and this server helps an AI assistant work with Electron projects.

Use it when developing, auditing, testing, or diagnosing the electron-mcp project, especially its IPC communication, preload bridges, security settings, content policies, and build process.

It gives the assistant the project's architecture, security patterns, build details, and shared analysis rules, reducing guesswork when changing or reviewing the code.

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 5.1	$0.01043	$0.01043
Opus 5	$0.00522	$0.00522
Sonnet 5	$0.00209	$0.00209
Haiku 4.5	$0.00104	$0.00104

Security

Grade A, and why

electron-mcp CLAUDE.md 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 8d ago.

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.

How it starts

The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

electron-mcp

Electron.js MCP server — IPC scaffolding, security auditing, build diagnostics, and development intelligence for AI assistants.

Architecture

18 tools total, across seven tool modules plus two shared support modules.

src/index.ts — Entry point. Registers all tools with McpServer, appends the knowledge footer, handles version subcommand.
src/version.ts — Resolves the package version (esbuild __VERSION__ define, with a tsc-path package.json fallback).
src/knowledge.ts — Single source of truth for the embedded-knowledge vintage (KNOWLEDGE_VERSION) and the knowledgeFooter() appended to tool output.
src/static-analysis.ts — Shared lexical-scrub utilities (stripComments, stripCommentsAndStrings, unsafeOpenExternalCallSites) used by the analysis tools so each inherits the same comment/string handling.
src/tools/ipc.ts — IPC & process architecture tools (5 tools): scaffold channels, generate preload bridges, audit IPC security, window manager, process model explanation.
src/tools/security.ts — Security tools (4 tools): comprehensive audit, fuses config, CSP generation, security linting.
src/tools/build.ts — Build & distribution tools (4 tools): error diagnosis, auto-update config, deep linking, project scaffolding.
src/tools/migration.ts — Migration tools (2 tools): version migration checklist, deprecated API scanner. Contains embedded breaking changes database for Electron v28-v41.
src/tools/performance.ts — Performance tool (1 tool): detects 7 official anti-patterns.
src/tools/reference.ts — Reference tool (1 tool): authoritative concept explainer with 8 topics.
src/tools/knowledge.ts — Knowledge metadata tool (1 tool): electron_knowledge_version reports the embedded-knowledge vintage and supported version range.

Key differences from other @yawlabs MCPs

This MCP does NOT wrap a REST API. It is a development intelligence server:

No API key or environment variables required
Tools generate code and configuration rather than fetching data
Tools analyze code provided as input (static analysis)
Contains embedded Electron knowledge (breaking changes, security rules, best practices)
All tools are read-only — no side effects

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.
