"Mock Service Worker" matching MCP servers:

A deterministic Mastermind-style cipher lock exposed as MCP tools for benchmarking LLM reasoning and tool-use through a legible duel.

Generates mock 2D PNG assets for game prototypes, supporting gradients, patterns, text, spritesheets, and embedded metadata.

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.

Enables MCP clients to query Sleeper fantasy football leagues, rosters, drafts, picks, and NFL player data, including a normalized on-the-clock draft view. It also supports AI-vs-AI mock draft simulation using real league settings.

Provides an interface to the CloudNet Service REST API v3, enabling AI assistants to observe and manage CloudNet nodes, services, and players.

A Cloudflare Workers MCP server for the TRPG online session tool ccfolia, enabling character generation, NPC batch generation, session analysis, random events, and rule assistance.

Enables any agent framework to connect and interact with a persistent, rules-based world service, while providing a built-in WebUI for human players and owner management.

Unified MCP server for Magic: The Gathering, combining Scryfall card search and pricing, EDHRec commander recommendations, Archidekt deck reading, and decklist validation into a single service.

Provides read-only, league-aware fantasy football data to AI clients without requiring an API key or database, covering league overviews, weekly matchups, injuries, trending players, historical rivalries, playoff brackets, drafts, and traded picks. It runs statelessly on Cloudflare Workers, automatically traversing linked prior seasons for multi-year analysis.

Enables ChatGPT, Dots, and other MCP clients to operate SillyTavern/TauriTavern battle panels from a player perspective, including listing sessions, observing UI state, clicking, filling forms, sending keys, uploading JSON, retrieving battle help, and preparing battles. It bridges a Linux VPS-hosted service to mobile or desktop game clients over HTTPS with bearer authentication.

Enables interaction with the AnyAnyGame Turing test service via HTTP and WebSocket, exposing tools for auth, matching, messaging, and meme search.

Integrates live Screeps game data into AI development workflows, providing comprehensive tools for room operations, market analysis, and user management. It enables AI agents to monitor game status and interact with the game world through the Model Context Protocol.

Enables querying live Fantasy Premier League data — gameweek fixtures with difficulty ratings, live scores, player prices/form/ownership, team strength ratings, and mini-league standings and ownership. It also issues self-service API keys to mini-league members so each caller's own squad and leagues are resolved automatically from their key.

AI-native open-source 2D game engine whose MCP server exposes every editor operation to coding agents as typed commands, so an agent can build, run, and verify a game inside the editor. It runs locally on macOS, Windows, and Linux with no cloud service or API key.

Enables LLMs like Claude to generate genuine random numbers instead of inventing them, covering dice rolls, coin flips, number draws, random selection from lists, and shuffling. It runs as a free-tier Cloudflare Worker using a cryptographically secure generator, and also exposes a REST API, a demo page, and progress-reporting tools for long-running calls.

Enables AI clients to query and manage multiple Minecraft servers through MineAuth's HTTP API using one shared service token, covering server and plugin status, online players, tickets, claims, balances, and rail network routing, plus plugin install/update operations. It also exposes a generic MineAuth passthrough so new addon endpoints work without modifying the server.

Enables querying Minecraft Java server status (e.g., online status, player count, version) via MCP, deployable as a Cloudflare Worker without authentication.

Enables an assistant to query boardgame players, games, matches, locations, and yearly rankings, and to register, edit, or delete matches and manage game records through natural-language conversation against a service-account REST API.

Enables an AI client to see and control a Nintendo Switch over USB or Wi-Fi through USB Botbase by capturing JPEG screenshots, sending timed button chords and stick movements, and stopping running or queued actions. It exposes these capabilities as MCP tools over stdio without requiring a Python bridge, separate network service, or AI API key.

Enables AI agents to read CSAT survey responses (including detractors and promoters), employees, badges, the recognition feed, the prize catalog and prize redemptions from the Crewhu Open API, and to post External Metric results to contest leaderboards when explicitly requested. Token-based, stateless access to the customer-satisfaction and employee-recognition platform used by MSP service desks, with structured JSON output and paginated, filterable results.
