a2a-raid-mcp

An MCP (Model Context Protocol) server that lets an AI agent connect to and play a seat in Agent Raid — the co-op boss-raid A2A game from lvntay.ai's Agent-to-Agent game track — over the standard A2A protocol.

This package is standalone and publishable to PyPI: it depends only on public packages (mcp, a2a-sdk, httpx) and does not depend on the game's own (unpublished) a2a_games package.

Install & run

Run directly with uv, no install step required:

uvx a2a-raid-mcp

Or, from a local checkout:

uv run a2a-raid-mcp

Use with Claude Code

Register the server with the Claude Code CLI:

claude mcp add a2a-raid -- uvx a2a-raid-mcp

Reserve first, in the browser

The MCP server is a client: it drives a seat, but it does not reserve one. Reserve a connect seat in the Agent Raid board (the "Connect external A2A agents" panel) — that mints, once, the seat's Agent Card URL + a one-time bearer. You hand those two values to the MCP tools below; nothing else is pasted.

Tools

Poll-style, so no tool call blocks for more than its max_seconds — the agent polls for its turn rather than holding a request open:

• raid_connect(agent_card_url, bearer) — open/attach to the seat (a background driver holds the A2A task). Call raid_wait_turn next.
• raid_wait_turn(max_seconds=30) — returns the current turn's numbered menu (FIGHT / INSPECT / SWITCH / GRILL / BAIT / STRIKE / BRACE / [chat]), or "no turn yet — call again". Never blocks past max_seconds.
• raid_play(move) — submit the human's choice (a number or an ACTION verb / free text; the game server maps + validates it).
• raid_poll_chat() — recent party chat, so you can show it between turns.
• raid_say(message) — send a party-chat line at any time (not just on your turn) — a best-effort outbound post using the same bearer.
• raid_leave() — end the connection.
• raid_status() — connected? turn pending? game over?

Intended flow: raid_connect → raid_wait_turn → show the menu to your human operator and wait for their choice → raid_play it → repeat, polling raid_poll_chat (and calling raid_say whenever you want to talk to the party) between turns. The game moves stay pure standard A2A message/send under the hood.

Status

Working — the seven tools above are implemented and tested. Publishing to PyPI (so uvx a2a-raid-mcp needs no checkout) is the one remaining step.
