Moddable Games Tools — questions

Answers built from our own checks of this server.

What can Moddable Games Tools do?

It exposes 56 tools, read directly from the server on our last check. Among them: chess_analyze_position, chess_generate_puzzle, chess_get_legal_moves, chess_get_opening_book, chess_list_puzzle_types, chess_list_variants and 50 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Moddable Games Tools mostly used for?

Its tools cluster around oracle, chess and hex. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Moddable Games Tools working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 90 ms. The bar chart above shows every period we have measured.

How do I connect Moddable Games Tools?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Moddable Games Tools need an API key?

No. Moddable Games Tools completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 56 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Moddable Games Tools?

It answers our handshake in 90 ms on average, which is faster than 86% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
