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 | $0.01812 | $0.01812 |
| Opus 5.5 | $0.00725 | $0.00725 |
| Sonnet 5.5 | $0.00362 | $0.00362 |
| Haiku 4.5 | $0.00181 | $0.00181 |
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 22d 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 — 75 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 three shared support modules.
src/index.ts— Entry point. Registers all tools with McpServer, appends the knowledge footer, handles version subcommand.src/instructions.ts— The MCPinstructionsstring (routing guidance, plain ASCII, under 2000 bytes; pinned bysrc/instructions.test.ts).src/version.ts— Resolves the package version (esbuild__VERSION__define, with a tsc-pathpackage.jsonfallback).src/knowledge.ts— Single source of truth for the embedded-knowledge vintage (KNOWLEDGE_VERSION) and theknowledgeFooter()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_versionreports the embedded-knowledge vintage and supported version range.
Key differences from other @yawlabs MCPs
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.

electron-mcp CLAUDE.md is an instructions file published in the GitHub repository YawLabs/electron-mcp (2 stars, last pushed yesterday), licensed MIT. It adds 1,812 tokens to every session, about $0.0072 per session on Opus 5.5. 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 2026-08-31.
