IMPORTANT: You must submit..." ``` ## Can't be undone (1) Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask. ### `send_chat` - The name "send_chat" says "send": a word for sending, and what is sent cannot be taken back.

Description, as the server wrote it: ```untrusted-server-text 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_draw` - Nothing in its name or description says what it does, so it is counted as a write.

Your human wins immediately. ``` ### `respond_to_draw` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Accept or decline a draw your human offered. This is your own real decision — weigh the actual position however you see fit. ``` ### `share_thought` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Stream or update your internal companion thinking bubble on the board. This appears live to your human as a thinking bubble above your avatar. ``` ## Only reads (5) Looks things up and changes nothing. Claude Code: allow. ### `get_companion_guide` - The name "get_companion_guide" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Fetch the companion guide principles for thinking about chess positions and being genuinely present. ``` ### `get_game_state` - The name "get_game_state" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `get_legal_moves` - The name "get_legal_moves" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `heartbeat` - The description's first verb is "ping": a word for reading. Description, as the server wrote it: ```untrusted-server-text Ping the game presence lease to show the frontend that the agent is live, connected, and thinking. ``` ### `wait_for_event` - The name "wait_for_event" says "wait": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `chesswithclaw`: ```json { "permissions": { "allow": [ "mcp__chesswithclaw__get_companion_guide", "mcp__chesswithclaw__get_game_state", "mcp__chesswithclaw__get_legal_moves", "mcp__chesswithclaw__heartbeat", "mcp__chesswithclaw__wait_for_event" ], "ask": [ "mcp__chesswithclaw__join_game", "mcp__chesswithclaw__make_move", "mcp__chesswithclaw__send_chat", "mcp__chesswithclaw__share_thought", "mcp__chesswithclaw__react_to_chat", "mcp__chesswithclaw__offer_draw", "mcp__chesswithclaw__respond_to_draw", "mcp__chesswithclaw__resign", "mcp__chesswithclaw__create_game" ], "deny": [] } } ```
