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 | $0.02504 | $0.02504 |
| Opus 5 | $0.01252 | $0.01252 |
| Sonnet 5 | $0.00501 | $0.00501 |
| Haiku 4.5 | $0.00250 | $0.00250 |
Grade A, and why
wechat-official-account-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 11d 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

Tech Stack: Node.js 18+, TypeScript, MCP SDK, SQLite, Axios, Zod, Express (for SSE transport), crypto-js (for encryption)
Essential Commands
Development
# Build the project (cleans and compiles TypeScript)
npm run build
# Production build (with stricter tsconfig)
npm run build:prod
# Type checking without emitting files
npm run check
# Lint code
npm run lint
# Run tests
npm test
Running the Server
# Development mode (direct with tsx)
npm run dev -- mcp -a <app_id> -s <app_secret>
# Start built server
node dist/src/cli.js mcp -a <app_id> -s <app_secret>
# Using npx (recommended for users)
npx wechat-official-account-mcp mcp -a <app_id> -s <app_secret>
CLI Options
-a, --app-id <appId>: WeChat App ID (required)-s, --app-secret <appSecret>: WeChat App Secret (required)-m, --mode <mode>: Transport mode -stdio(default) orsse-p, --port <port>: Port for SSE mode (default: 3000)
Packaging & Release
# Local package testing
npm run pack:test
# Dry run pack (show what would be included)
npm run pack:dry
# Full build with verification

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.
