Install

How do I install the Moddable Games Tools MCP server?

Moddable Games Tools is a hosted endpoint at https://tools.moddable.games/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

Common questions

What is the Moddable Games Tools MCP server?

Moddable Games Tools is an MCP server listed in the public MCP registry as games.moddable.tools/moddable-games-tools. 15 tools for chess variant analysis, hex map generation, and board game utilities. This page covers its hosted endpoint (https://tools.moddable.games/mcp).

Is the Moddable Games Tools MCP server safe to use?

Moddable Games Tools scores 73 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the Moddable Games Tools MCP server expose?

Moddable Games Tools exposes 89 tools: chess_generate_puzzle, chess_list_puzzle_types, chess_list_variants, chess_get_legal_moves, chess_analyze_position, and 84 more. Their descriptions and schemas cost roughly 5,593 tokens of context every time the server is loaded.

Does the Moddable Games Tools MCP server require authentication?

No. We connected to Moddable Games Tools without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the Moddable Games Tools MCP server still maintained?

Moddable Games Tools is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
