"Spec-WorkFlow documentation or implementation" matching MCP servers:

Provides access to comprehensive Riot Games API documentation for League of Legends, Teamfight Tactics, Valorant, and Legends of Runeterra, including endpoint details, parameters, and response formats.

Enables a bot to inspect, query, create, edit, and script Roblox Studio instances in token-cheap batches, plus run Luau, playtests, screenshots, and inputs through Roblox's official Studio MCP connection. It runs locally over stdio or an authenticated local HTTP endpoint, returning small structured answers instead of dumping whole games into context.

MCP server exposing Elden Ring game data (weapons, spells, talismans, armour) with optional corpus ingestion for lore, tier rankings, and community notes.

Enables assistants to search and look up Riftbound TCG cards, list sets, and search or fetch public decklists (resolving stored card UUIDs into real card names) through the community card database's API, so questions about cards absent from model training data can be answered with real data.

Enables AI coding assistants to access documentation, live API tools, and workflow prompts for integrating a game/app backend service into Godot, Unity, and Unreal Engine projects, including auth, leaderboards, cloud saves, remote config, localization, news, gift codes, feedback, logs, crash reporting, email, and admin dashboard management.

Analyzes chess positions via Stockfish, returning best moves and evaluations from FEN or PGN input.

A read-only MCP server that reports free games on Epic Games Store and GOG.com using public endpoints, without requiring any account or credentials.

MCP server that lets AI assistants read and query Dwarf Fortress world legends: search events, objects, and properties, or read summaries and base rates to distinguish real patterns from common traits.

Provides full class documentation for the Binding of Isaac modding API, enabling AI assistants to access complete class pages with methods, enums, and tutorials to avoid hallucination.

Enables AI-powered image generation and curation for Foundry VTT tabletop art, letting users create portraits, tokens, handouts, and scene backgrounds from prompts via a local headless ComfyUI workflow.

Holonovel turns a tabletop RPG rulebook and an AI client into a running game. The server enforces every rule and remembers your campaign as structured state the AI can't forget; the AI just narrates. D&D 5e, Starfinder, or any rulebook.

Enables agents to generate uniquely-solvable Sudoku puzzles, validate partial or complete grids, and solve puzzles using SMT solving with Z3, all through stateless MCP tools.

Enables rolling of standard RPG dice (d4, d6, d8, d10, d12, d20, d100, etc.) using dice notation like '3d6' or 'd20', and returns detailed results including individual rolls and totals.

Provides AI coding assistants with access to AccelByte Gaming Services (AGS) Extend SDK functions and models through searchable symbols and detailed documentation. Helps generate SDK code by exposing context about available functions, models, and templates for creating Extend app projects across multiple languages (Go, C#, Java, Python).

Enables MCP-compatible AI assistants to read Path of Exile 2 character data and recent in-game events, and to surface advisories to the user via notifications, speech, or log files.

An MCP server that provides live status updates for the Eco via Sirens game server, displaying meteor countdowns, player statistics, and world information directly within Claude Desktop. It also serves as a minimal reference implementation for building MCP Apps in Python without complex tooling.

An MCP server that gives AI coding assistants access to the World of Warcraft addon API documentation, FrameXML/AddOn UI source code, and the Warcraft Wiki across all four client flavors.

Provides read-only access to Pal Save Editor's workflow, safety boundaries, FAQ, and official links for MCP-compatible AI clients.

Provides read-only access to reaction time test catalog, measurement rules, FAQ, and official links for AI clients like Claude Desktop. Cannot run tests; it only exposes documentation context.

Enables tool-using language models to play Lemonade Tycoon Deluxe as a text-only business benchmark, exposing game UI state and actions as semantic MCP tools without vision or shell access.
