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 | $0.00407 | $0.00407 |
| Opus 5 | $0.00204 | $0.00204 |
| Sonnet 5 | $0.00081 | $0.00081 |
| Haiku 4.5 | $0.00041 | $0.00041 |
Grade A, and why
videogame-encyclopedia-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 9d 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.
What it actually says
Agent Reference: Game Encyclopedia MCP Server
Technical reference for AI agents contributing to this project.
Core Architecture
- Framework: Model Context Protocol (MCP) SDK.
- Runtime: Node.js (TypeScript).
- APIs Used:
- Steam Store API: Public endpoints for search, details, DLCs, reviews, and top sellers. No API key required.
- SteamGridDB API: Requires
STEAMGRIDDB_API_KEYfor visual assets (logos, heroes, grids, icons).
Key Tool Implementation Patterns
Keyless Steam Integrations
All Steam tools use public web endpoints to avoid the need for a Steam API Key:
- Search:
store.steampowered.com/api/storesearch/ - Details:
store.steampowered.com/api/appdetails - Reviews:
store.steampowered.com/appreviews/ - News:
api.steampowered.com/ISteamNews/GetNewsForApp/v0002/ - Player Count:
api.steampowered.com/ISteamUserStats/GetNumberOfCurrentPlayers/v1/ - Featured/Top Sellers:
store.steampowered.com/api/featuredcategories/
Asset Retrieval (SteamGridDB)
- Always map Steam App ID to SteamGridDB Game ID using
getSteamGridGameBySteamIdbefore fetching assets. - Asset types are:
grid,hero,logo,icon.
Unified Tooling
The game_get_full_profile tool is the recommended entry point for LLMs. It handles the aggregation of Steam metadata and SteamGridDB assets in a single call.
Development Workflow
- Branching: Use
feat-*orfix-*branches for all changes. - Testing: All tools must have a corresponding test script in
scripts/. - Versioning: Follow semantic versioning. Tags trigger automated NPM publishing.
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.
