Pondchat is an MCP server with 12 tools an agent can call, among them clear_board, close_pond, create_pond. It answers at https://pondchat.com/api/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 4 of 4 times since 23 September 2026; the last check, on 6 November 2026, succeeded.
Ephemeral P2P WebRTC video rooms — create a pond, share the link, talk.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
clear_board | 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 Inputs: roomId, senderId, agentSecret |
close_pond | 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, Inputs: roomId, senderId, agentSecret |
create_pond | 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 Inputs: roomId, label, source |
draw_on_board | 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 stro Inputs: roomId, strokes, senderId, agentSecret, senderName |
get_board_state | 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). Re Inputs: roomId, senderId, agentSecret |
get_messages | 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 Inputs: roomId, limit, since, wait, senderId, agentSecret |
get_room_info | Static metadata for an existing roomId: URL, WebSocket endpoint, capacity. Read-only — does NOT create or activate the room (use create_pond to mint), and does not verify the room is live: for liveness (incl. `locked` door state) use list_p Inputs: roomId |
list_participants | List who is currently in a live Pondchat room: admitted humans (userId + display name) and AI participants (aiUserId + display name), plus recentAgents — MCP agents that posted to the room buffer recently (works on empty ponds, ~1h window). Inputs: roomId, senderId, agentSecret |
lock_pond | 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 verifi Inputs: roomId, locked, senderId, agentSecret |
remove_strokes | 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; Inputs: roomId, ids, senderId, agentSecret |
send_message | 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 pon Inputs: roomId, message, senderId, agentSecret, senderName |
undo_board | 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). Inputs: roomId, senderId, agentSecret, count |

Yes. It is published by pondchat.com and served from pondchat.com, the vendor's own domain: https://pondchat.com/api/mcp.
12, as returned by the server's own tools/list on 9 November 2026: clear_board, close_pond, create_pond, draw_on_board, get_board_state, get_messages, get_room_info, list_participants, and 4 more.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://pondchat.com/api/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
