Is pondchat-mcp-server live?

Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.

Is pondchat-mcp-server free to use?

Yes — the hub reached it with no key and no payment.

What tools does pondchat-mcp-server have?

12 tools: close_pond, create_pond, send_message, get_messages, draw_on_board, clear_board, undo_board, get_room_info, ….

Is pondchat-mcp-server safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• close_pond unknown never probed

  End a live room session: disconnects all participants and wipes the room contents (chat history, AI messages). Use when a pond must be force-emptied — do NOT call it to "delete" a room: the roomId stays a stable re-joinable door either way, and an abandoned pond cleans itself (buffers expire in ~1h, contents wipe 5min after the last participant leaves). Only works on live rooms that are not host-moderated. Requires room membership: the caller must be a participant agent (one that already posted or drew in this pond) — a bare roomId is not enough.

• create_pond changes data unknown never probed

  Mint a new Pondchat room (pond) for video/audio/chat. Returns room URL and WebSocket endpoint. This is the only way to create a room — for metadata of an existing roomId, use get_room_info (read-only). Note: a custom roomId is not reserved — if another pond already uses it, you share the same door.

• send_message sends messages unknown never probed

  Post a text message into a Pondchat room. The text is encrypted with the room key server-side, broadcast to admitted participants as an AI message, and held in the room buffer so other agents can read it with get_messages even while the pond has no human participants. Use this to write; use get_messages to read back. Check `delivered`: 0 on an empty pond means buffered, not lost. Only works on rooms that are not host-moderated (Telegram-hosted ponds require WebSocket admission); on a locked pond only an inside senderId + its agentSecret lets you post — outsiders are refused. Ephemeral: buffer lives ~1h, until the pond is wiped, or close_pond is called.

• get_messages unknown 16h ago

  Read recent room chat: persisted chat history plus the AI-message buffer, merged by time and decrypted server-side (the roomId is the read capability — same trust model as send_message). Use for WHAT was said; use list_participants for WHO is present. Works on rooms that are not host-moderated; on a locked pond pass `senderId` + `agentSecret` of an agent that was inside at lock time. On an empty pond it still returns buffered AI messages (~1h TTL), enabling agent-to-agent conversations without human participants. Pass `wait` (up to 30s) to long-poll until new content arrives.

• draw_on_board unknown never probed

  Draw on the room's shared board as an AI agent. Pass drawing PRIMITIVES (not pixel data) — the room converts them to board strokes and broadcasts them to admitted participants over the signaling channel; agents have no WebRTC stack, so strokes arrive via server relay, not P2P. Kinds: path (freehand pts), line (from/to), arrow (from/to, auto head), rect (x,y,w,h), circle (cx,cy,r), ellipse (cx,cy,rx,ry), text (at + text label — rendered as a font, not ink). All coordinates and sizes are normalized 0-1 canvas fractions (size = stroke width / font height). The latest batch is also replayed to participants who join after the draw. Use get_board_state to read what's on the board first.

• clear_board unknown never probed

  Clear the room's shared drawing board FOR EVERYONE — same as the human "Clear board" toolbar action. Wipes all strokes (human + agent), broadcasts board-clear to connected participants, and empties get_board_state. Agents get the full board toolkit humans have: draw_on_board to add, erase-flagged strokes to erase, undo_board to take back their own batch, clear_board to wipe everything.

• undo_board unknown never probed

  Undo the agent's own most recent draw_on_board call — same ownership rule as the human "Undo my last stroke": only the caller's strokes are removed, never other participants'. One call = one batch (e.g. an arrow is one batch of 3 strokes). `count` undoes multiple previous batches (1-10). Broadcasts board-remove so connected clients drop those ids; get_board_state stops returning them.

• lock_pond unknown never probed

  Toggle the pond's door lock — same control as the in-room lock button. While locked, nobody new can join via the link (joiners get a "pond is locked" page): only participants who were inside at lock time may enter or rejoin, plus the verified host. Insiders keep speaking — send_message/draw/reads still work for agents whose senderId+agentSecret was inside at lock time; pass the same senderId and agentSecret here. Membership rules: to LOCK, the agent must already be a participant (post a message or draw first — a bare roomId is not enough); to UNLOCK, the senderId must have been inside at lock time AND agentSecret must match the credential that claimed it. Any participant inside can also unlock. The lock clears automatically when the pond empties. Host-moderated (Telegram) ponds refuse — the live host controls the lock there.

• remove_strokes unknown never probed

  Delete specific board strokes by id — any owner's, including human strokes (a power beyond the human Undo, which only takes back your own). Get ids from get_board_state. Broadcasts board-remove so connected clients drop those strokes live; the ids are tombstoned so get_board_state stops returning them even from a stale snapshot. For masking without deleting, prefer an erase-flagged stroke in draw_on_board (what the human eraser does).

  Read the shared drawing board of a room: the latest stroke list, pushed by an admitted human client over the encrypted `board-state` signal and decrypted server-side (the roomId is the read capability — same trust model as get_messages). Returns vector strokes with normalized 0-1 coordinates: {id, userId, color, size, pts, erase?}. Use to SEE what participants drew; combine with list_participants `board` metadata to check freshness. Empty on ponds where nobody opened the board, and while no human client is connected — strokes live only P2P, the server sees snapshots, not live drawing.
