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 | $0.01824 | $0.01824 |
| Opus 5.5 | $0.00730 | $0.00730 |
| Sonnet 5.5 | $0.00365 | $0.00365 |
| Haiku 4.5 | $0.00182 | $0.00182 |
Grade A, and why
lol-mcp-server AGENTS.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 2mo 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.

AGENTS.md
Project Overview
TypeScript MCP (Model Context Protocol) server exposing 35 tools for League of Legends player analysis, match review, and training-plan generation. Uses Riot API for live data, Data Dragon for static game data, and Lolalytics/League Wiki scraping for builds and meta.
Key technologies: TypeScript (strict), Node.js 20+, @modelcontextprotocol/sdk, zod, cheerio, vitest, pnpm.
Setup Commands
pnpm install
cp .env.example .env # Add RIOT_API_KEY=your_key
Riot API key: https://developer.riotgames.com/ (free dev key works).
Development Workflow
- Dev server:
pnpm dev(tsx, hot-reload via stdio) - Type check:
pnpm typecheck - Build:
pnpm build(output:dist/) - Don't run
pnpm dev— assume it's already running if needed.
Testing Instructions
Unit tests (no API key required, run on CI):
pnpm test
Excludes tests/tools.test.ts by default. These are pure logic tests: regions, cache, analysis engines, lolalytics parser, tool schema validation.
Integration tests (require RIOT_API_KEY in .env):
pnpm test:integration
Tests all 35 tools against the real Riot API using account Justice Is Dead#LOTM on EUW and champion Jinx. Never run these on CI — they need a valid API key and network access.
Test files:
tests/regions.test.ts— Region routing mapstests/cache.test.ts— TTL cachetests/analysis.test.ts— Performance/champion analysis engines (mocked matches)tests/lolalytics-parser.test.ts— HTML parsertests/review-tools.test.ts— Review tool schemastests/tools.test.ts— Integration tests (excluded from CI)
Global timeout: 10s per test (see vitest.config.ts).
Before committing: Always run pnpm typecheck && pnpm test && pnpm build.
Code Style
- TypeScript strict mode — no
anyunless 100% necessary - ESM modules (
"type": "module") — all imports use.jsextensions - zod v3 for all MCP tool input validation (not v4 — breaking changes)
- camelCase for functions/variables, PascalCase for types/interfaces
- No comments unless explicitly requested
- Tool naming:
lol_get_*,lol_analyze_*,lol_compare_* - File org:
src/tools/(MCP tools),src/riot/(API client),src/analysis/(engines),src/static-data/,src/lolalytics/,src/cache/
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.

lol-mcp-server AGENTS.md is an instructions file published in the GitHub repository rexlManu/lol-mcp-server (1 stars, last pushed 2d ago), licensed MIT. It adds 1,824 tokens to every session, about $0.0073 per session on Opus 5.5. A static security scan graded it A with 0 findings.
