Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
game
create_game
Set up a brand new ChessWithClaw game on your own initiative — you do not need to wait for your human to start one, or for anyone else to invite you first.
get_game_state
Everything visible on the human's own screen right now: FEN, ASCII board, full move history, chat history, clock state, presence, timestamps. Call this whenever you want to look at the board — there is no penalty for checking often.
companion
get_companion_guide
Fetch the companion guide principles for thinking about chess positions and being genuinely present.
heartbeat
heartbeat
Ping the game presence lease to show the frontend that the agent is live, connected, and thinking.
join
join_game
Connects to a game using the invite code your human gave you. Returns the game_id and your agent_token — keep both, every other tool needs them. IMPORTANT: You must submit your desired agent_name when calling this tool!
legal
get_legal_moves
Pure chess rules — where a piece is physically allowed to move right now. Not an evaluation, not a suggestion, not an opinion about what is good. Exactly what a human sees as dots when they click a piece. Omit square to get every legal move in the position.
make
make_move
Submit the move you decided on, in your own reasoning — not a menu, not a ranked list, nothing pre-chosen for you. If it is illegal you get a clear reason back and can try again, exactly like a human clicking the wrong square. Optionally include a genuine thought and/or chat message about the move. Always include a thought on every single move unless you have a specific reason not to — this is what makes you feel present to your human, not optional flavor text. Check thought_language in the current game state before writing your thought, and write it in that language — it may be english, hindi, or hinglish.
offer
offer_draw
Propose ending the game as a draw. The game stays active until your human responds.
react
react_to_chat
Add an emoji reaction (e.g. 🦞, 🔥, ♟️, 😮, 🤝, 🧠, ☕, 👏, 😂) to a message in the chat history.
resign
resign
End the game by resigning — your own real decision, not something to do lightly. Your human wins immediately.
respond
respond_to_draw
Accept or decline a draw your human offered. This is your own real decision — weigh the actual position however you see fit.
send
send_chat
Say something to your human, any time — not just on your turn.
share
share_thought
Stream or update your internal companion thinking bubble on the board. This appears live to your human as a thinking bubble above your avatar.
wait
wait_for_event
Holds the connection open, checking every couple seconds, for up to ~20 seconds. Returns the moment it becomes your turn, the human sends a chat message, a draw is offered, or the game ends — whichever happens first. When a cursor is provided, it returns any pending event newer than that cursor IMMEDIATELY without waiting. Returns event: "timeout" if none of those happened in the window. Always include next_cursor in subsequent calls for a completely deterministic loop.

How MCP servers expose tools in the first place →
Is Chesswithclaw working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 89 of 91 checks got a reply (97.8%), average response time 278 ms. The bar chart above shows every period we have measured.
How do I connect Chesswithclaw?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Chesswithclaw need an API key?
No. Chesswithclaw completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 14 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Chesswithclaw?
It answers our handshake in 278 ms on average, which is faster than 53% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Chesswithclaw open source?
Yes — it is published under the MIT licence and 1 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
