library, gui: DeepSeek Harness is listed under Library › RTK with why RTK has no hook for it, not left out (lc on Discord) — RTK rewrites the shell command an agent is about to run, and dsh's hooks can only allow or deny one (its Claude Code bridge drops updatedInput; deepseek-harness's pre-tool-input-rewrite is only proposed), and rtk 0.51's init has no --agent dsh (rtk-ai/rtk#3847; the open #3934 only adds AGENTS.md text, which rewrites nothing). So the RTK tab left dsh out and it read as magpie not seeing it. rtkNoHook names it with the reason: the row has a No RTK hook tag (zh/ja/de) and a switch that can't be turned on, magpie library rtk prints the reason, and on/off for dsh answer it instead of "rtk has no hook for dsh". TestRTKNoHookListed and library-rtk-nohook.test.cjs (Chromium, WebKit, en/zh) are new and fail without the change. go vet, go build (darwin, GOOS=linux nogui, GOOS=windows) and go test -tags nogui ./... under a temp HOME pass (TestProvidersAnswerWhileListsComeIn and TestUserPath failed once under the full run's load and pass on their own).

 | MCP servers | A `Server` is a command or a URL (`http`, `sse`). `mcpFile` encodes it in each agent's own format (one `mcpFormat` per agent family) and merges it with the user's own fields for that entry. `Also` files get the same servers; `Extra` files are only read when importing. `CheckServers` connects as an agent would and keeps the result in memory only. A server that needs OAuth is signed in once in magpie, and agents reach it through the gateway's `/mcp/<name>` (#615). | [`mcp.go`](../../internal/library/mcp.go), [`mcp_check.go`](../../internal/library/mcp_check.go), [`mcp_signin.go`](../../internal/library/mcp_signin.go) |
