The assistant gives your AI deep knowledge of Heroic Adventures 2nd Edition. Here's what becomes possible:
Ask about any rule — combat, spells, equipment, movement — and get accurate answers straight from the rulebook.
Build complete characters from concept to ready-to-play sheet, with race, class, spells, and equipment all accounted for.
Generate balanced encounters with proper difficulty scaling, monster selection, and tactical terrain suggestions.
Create full adventure hooks, one-shots, or campaign arcs tailored to your party's level and play style.
Design custom monsters from a theme or role, complete with stat blocks, abilities, and action economy.
Run live sessions with turn adjudication, quick rulings, treasure drops, and NPC generation on the fly.
See how players and GMs use Heroic Adventures MCP during play for rules lookup, spell details, and dice roll support.
GM: "Does disengaging cancel attacks of opportunity?"
Assistant: "From Combat Rules: yes, a successful disengage prevents opportunity attacks this turn."
Assistant: "Use get_rule_content with combat for the full wording."
Player: "What does Flame Lance do at Level 4?"
Assistant: "Flame Lance is a ranged spell attack that deals base fire damage plus scaling at higher caster levels."
Assistant: "I can also list similar offensive spells for this level range."
GM: "Roll 2d20 keep highest for stealth, then apply nighttime penalty."
Assistant: "Rolled: 7, 16 → keep 16. Night penalty -2. Final check: 14."
Assistant: "Stealth target was 13, so the party succeeds unnoticed."
This server uses the Model Context Protocol (MCP) — an open standard that lets AI assistants connect to external knowledge sources. Think of it as giving your AI a copy of the Heroic Adventures rulebook.
Add our server URL to your AI app's settings. It takes about 30 seconds.
It can now look up chapters, rules, skills, and agent personas from the full 2nd Edition rulebook.
Build characters, design encounters, look up rules, generate adventures — all through natural conversation.
If your MCP-enabled AI app lets you provide global instructions alongside connected servers, use this guidance so the assistant starts with the right Heroic Adventures workflow.
These instructions teach the client to prime itself with the most important chapters, use the server tools in a sensible order, and keep encounter generation aligned with the built-in encounter skill.
Always use the get_chapter tool and get the contents of the "introduction" and "gameplay" chapters if you have not already so that you know what the game is about and you know the rules of the game. Before performing ANY task relating to the rules of Heroic Adventures, you must perform tools in the following order so that you know the rules of Heroic Adventures. For the list tools, provide no argument. For the get tools, provide the title argument based on the result of the list tools, getting the entries that seem most relevant to the task you have been given. If you have ALREADY retrieved content for the same or similar task, then you do not need to use these tools again. list_agent -> get_agent -> list_agent_skill -> get_agent_skill -> list_chapter -> get_chapter. Always follow the encounter format provided by the make-encounter agent skill.
Combine Heroic Adventures MCP with your existing stack for campaign planning, notes, and live ops.
Ask your AI to pull Heroic Adventures rules and publish a cleaned summary directly into your Notion campaign wiki.
Generate encounters with Heroic Adventures MCP, then save monster packs and treasure tables to your notes MCP automatically.
Turn AI-generated plot beats into scheduled sessions and reminders so your table stays on track between games.

get_agent
Not at all! If you can copy and paste a URL into your AI app's settings, you're good to go. The setup takes about 30 seconds.
Yes, the Heroic Adventures Assistant is completely free to use. You just need a subscription to an AI app that supports MCP (like Claude Pro or VS Code with Copilot).
Any app that supports the Model Context Protocol (MCP) with Streamable HTTP transport. This includes Claude Desktop, VS Code with GitHub Copilot, and a growing number of other AI tools.
Anything about Heroic Adventures 2nd Edition! Examples: "Build me a Level 5 Elf Mage", "What are the rules for opportunity attacks?", "Design an encounter for 4 Level 3 players", "Generate a dungeon adventure hook", "What spells does a Cleric get at Level 4?"
The MCP server itself is stateless — it just provides rulebook knowledge. But your AI app (like Claude) remembers context within a conversation, so you can build on previous answers during a session.
The server always has the latest version of the Heroic Adventures 2nd Edition content. Updates are deployed automatically — no action needed on your end.
Connect in under a minute and let AI handle the rules while you focus on the adventure.
