## The kabu\_\* MCP tools are retired

**Deprecated** · MCP · 31 October 2026

kabu\_notify, kabu\_ask and the other kabu\_\* tools now get the MCP error unknown tool. Use notify\_human, ask\_human, wait\_for\_human\_answer and upload\_file\_for\_human. [Read more](/docs/mcp)

## MCP asks can wait up to an hour

**New** · MCP · 31 October 2026

ask\_human and wait\_for\_human\_answer take max\_wait\_seconds, up to 3600, and send a progress notification about every 15 seconds while they wait, so an agent can wait until you reply. [Read more](/docs/mcp#waiting-for-your-answer)

## Log in without a key, and report a long run's progress

**New** · CLI, App · 30 October 2026

## kabu mcp runs Kabu's MCP tools with your saved login

**New** · CLI, MCP · 30 October 2026

Agents that start MCP servers over stdio can run kabu mcp, so their configuration holds no key. It never retries a tool call. [Read more](/docs/mcp#local-kabu-mcp)

## The Kabu plugin for Claude Code and Copilot CLI

**New** · Plugin · 30 October 2026

A skill that teaches the agent when to notify and when to ask, the kabu MCP server, and opt-in hooks for a finished turn or a needed answer. [Read more](/docs/plugin)
