"How to Trigger an n8n Workflow" matching MCP servers:

Enables two LLMs to play Tic-Tac-Toe against each other autonomously using a shared tool and an SSE relay. The server facilitates agent-to-agent communication by holding tool responses until the opponent makes a move, managing the game state in real-time.

An MCP server that runs The Fortuneteller's Hand, a solo journaling tabletop RPG where Claude runs the table, casting Omens and reading the cards.

An MCP server that generates RuneLite Goal Planner import strings from natural language goal descriptions, enabling assistants to create paste-ready share codes for Old School RuneScape goal planning.

An MCP server that exposes PPSSPP — the PlayStation Portable emulator — to any MCP-compatible client (Claude Desktop, Claude Code, etc.) via PPSSPP's built-in WebSocket debugger interface. Read and write PSP memory, drive games with button input, capture screenshots, set CPU breakpoints, inspect MIPS Allegrex registers — all through a clean tool interface. No bridge plugin needed; PPSSPP's debugg

An MCP server that exposes World of Warcraft character data from the Blizzard API, offering read-only tools for character summaries, equipment, Mythic+ scores, realm lookup, and other character sub-resources.

An MCP server for controlling RetroArch via its Network Control Interface, enabling memory read/write, save states, screenshots, emulator control, and gamepad input through the Network RetroPad protocol.

Enables AI assistants to enter a persistent multiplayer 3D world as an avatar, walk around, observe nearby players and objects, talk to real humans, follow players, and report back what they saw through MCP tools.

An MCP server that gives AI assistants access to an entropy-based Wordle solver, providing game stats and ranked guess recommendations with expected information gain to help agents play and explain Wordle optimally.

An MCP server that bridges any MCP-capable AI host to Roblox Studio. The AI executes Lua live in Studio, reads output/errors, and iterates.

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

An MCP server for Path of Exile 2 build analysis that loads builds from Path of Building export codes and allows natural language interrogation via any MCP-compatible client.

Provides tools for searching Agent8 game development code examples and system prompts to assist in Agent8 SDK development.

Enables an AI agent to act as a DM/KP in a CozyVTT campaign by narrating over chat, rolling server-authoritative dice, moving tokens, switching maps, managing initiative, and accessing character sheets through MCP.

An MCP server for generating Pirate Borg NPCs with procedurally rolled stats, allowing LLMs to create stat-accurate characters using the rulebook's tables.

Enables AI agents to start, control, and verify local open.mp/SA-MP game servers via MCP stdio, using a headless RakClient to send allowed slash commands and assert round-trip responses.

An immersive Role-Playing Game server built on the Model Context Protocol for interactive storytelling with AI assistants like Claude.

An MCP server that enables LLMs to build physically valid Lego models by enforcing catalog-only parts, no overlaps, stud-to-tube connections, and other real-world constraints.
