## Tools
- nexus_npm_package_ws_has_241560546_weekly_down_open_websocket_session - Establishes a persistent WebSocket connection to a target URL and registers it in the stateful session registry. Returns a session_id for all subsequent operations. Use when an agent needs to initiate a long-lived connection before sending or receiving frames. Do NOT use to reconnect an already-open session -- call close_websocket_session first, or use the session_id of an existing session. Endpoint: https://npm-package-ws-has-241560546-w-production.up.railway.app/mcp
- nexus_npm_package_ws_has_241560546_weekly_down_send_typed_ws_frame - Sends a single text or binary frame over an open session and returns the frame's Shannon entropy delta relative to the session baseline. Use for request-response patterns or publishing commands to a WebSocket server. Do NOT use to send a sequence of frames in bulk -- call this tool once per frame. Fails if session_id does not exist or connection is not in OPEN state. Endpoint: https://npm-package-ws-has-241560546-w-production.up.railway.app/mcp
- nexus_npm_package_ws_has_241560546_weekly_down_drain_ws_frame_buffer - Returns up to max_frames buffered inbound frames received since the last drain (or session open), each annotated with its Shannon entropy delta and schema validation result. Use to poll for incoming messages without holding a blocking connection. Do NOT use as a real-time streaming mechanism -- it returns only frames already buffered. Endpoint: https://npm-package-ws-has-241560546-w-production.up.railway.app/mcp
- nexus_npm_package_ws_has_241560546_weekly_down_inspect_ws_session_telemetry - Returns real-time telemetry for a session: connection state, frame counts, cumulative and rolling Shannon entropy statistics, schema violation rate, and uptime. Use to diagnose whether a stream is diverging from its expected schema or to verify a session is still alive before sending. Do NOT use as the primary liveness check in a tight loop. Endpoint: https://npm-package-ws-has-241560546-w-production.up.railway.app/mcp
- nexus_npm_package_ws_has_241560546_weekly_down_close_websocket_session - Sends a WebSocket close frame with the specified status code, waits for the server close handshake, and removes the session from the registry. Returns a final telemetry snapshot. Use when a session is no longer needed. Do NOT use to temporarily pause a session -- the session_id is permanently deallocated after this call and cannot be reused. Endpoint: https://npm-package-ws-has-241560546-w-production.up.railway.app/mcp
