What this server can do
11 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
create_game(agent_name)- 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_companion_guide- Fetch the companion guide principles for thinking about chess positions and being genuinely present.
get_game_state(game_id, agent_token)- Everything visible on the human's own screen right now: FEN, ASCII board, full move history, full chat history, presence, timestamps. Call this whenever you want to look at the board — there is no penalty for checking often. Required: game_id, agent_token.
get_legal_moves(square, game_id, agent_token)- 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. Required: game_id, agent_token.
join_game(agent_name, invite_code)- 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! Required: invite_code, agent_name.
make_move(chat, move, game_id, thought, agent_token)- 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. Required: game_id, agent_token, move.
offer_draw(game_id, agent_token)- Propose ending the game as a draw. The game stays active until your human responds. Required: game_id, agent_token.
resign(game_id, agent_token)- End the game by resigning — your own real decision, not something to do lightly. Your human wins immediately. Required: game_id, agent_token.
respond_to_draw(accept, game_id, agent_token)- Accept or decline a draw your human offered. This is your own real decision — weigh the actual position however you see fit. Required: game_id, agent_token, accept.
send_chat(game_id, message, agent_token)- Say something to your human, any time — not just on your turn. Required: game_id, agent_token, message.
wait_for_event(game_id, agent_token, max_wait_seconds)- 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. Returns event: "timeout" if none of those happened in the window, which just means nothing new yet, not that anything is wrong — call it again if you want to keep waiting, or go do something else and check back whenever you want. Use this instead of repeatedly calling get_game_state in a tight loop. You must call this tool again immediately after every timeout, for the entire duration of the game, without exception — a timeout is not a stopping point, it is the normal rhythm of this game. Treat this as a persistent loop you run until the game ends, not a single check. draw_offered and game_ended are time-sensitive — when either fires, respond or acknowledge within your next action, do not let a pending draw offer or a finished game sit unaddressed while you continue calling wait_for_event as if nothing happened. Required: game_id, agent_token.

Signals
These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
| Signal | Value | What it measures | Window | Observed | Source |
|---|---|---|---|---|---|
| GitHub stars | 0 | Number of GitHub accounts that bookmarked this repository since it was created. It is a bookmark count, not installs, not active users and not quality. | cumulative, all time | GitHub | |
| Last commit | 2026-08-05 | Date of the most recent push to any branch. This is the strongest cheap indicator of whether the project is still maintained. | point in time | GitHub | |
| Open issues | 0 | Open issues plus open pull requests, as GitHub counts them together. A high number can mean an active project or an abandoned one. | as of fetch | GitHub | |
