Watch progress, logs, tasks and subscriptions

A server keeps talking while it works: progress notifications, log messages, task status, resource updates. mcp-tui shows each as it arrives.

Progress, server logs, tasks and subscriptions. Watch progress notifications and server logs while a long tool runs, run a call as an MCP task and wait for it, and follow a resource as it changes.

Progress and server logs during a call

tool call sends a progressToken with every request and redraws the latest notifications/progress on one stderr line. --server-log-level asks the server for log messages at that level and prints each one:

mcp-tui --url http://127.0.0.1:8931/mcp --server-log-level info \
  tool call escalate_ticket ticket_id=T-1041

🚀 Executing tool...
server log [info] acme.desk: escalate_ticket T-1041: Paging the on-call engineer
server log [info] acme.desk: escalate_ticket T-1041: Notifying the account manager
server log [info] acme.desk: escalate_ticket T-1041: Raising priority to urgent
✅ Tool executed successfully

Notifications travel separately from the response, so the last log line can arrive after the result has printed. On 2026-07-28 the log level rides in every request’s _meta; on older versions mcp-tui sends logging/setLevel once after connecting.

Run a call as a task

With --task, tools/call returns a task handle and the result comes later. --wait follows the task to its end and prints the result as a direct call would; --watch-notifications shows each tasks/status on the way:

mcp-tui --cmd mcp-server-everything --args stdio --watch-notifications \
  tool call simulate-research-query topic="MCP transports" --task --wait

Without --wait the command prints the handle and the task get / task result commands to follow up with. See Tasks for both wire forms (the 2025-11-25 experimental feature and the 2026-07-28 extension).

Follow a resource

mcp-tui --url http://127.0.0.1:8931/mcp resource watch acme://status/queue --count 3

resource watch subscribes and prints one line per notifications/resources/updated until --count updates, Ctrl-C, or an explicit --timeout. On 2026-07-28 it listens on a per-URI subscriptions/listen stream; before, it uses resources/subscribe.

In the TUI, s on the Resources tab watches the selected resource and the Events tab lists every notification as it arrives.
