DeepSeek Harness Plugin

Fish121380/auto-mouse

Stars ★ 2 Category Tools & Capabilities Added 2026-08-23

Windows desktop UI context picker for Codex, DeepSeek Harness, and MCP clients: select windows, UI elements, or screen regions with hover highlighting, UI Automation, screenshots, and local OCR, then review and approve Markdown/JSON context before output.

Install

# from GitHub (first run asks for allowBuilds approval — follow the hint, retry)

dsh plugin --profile web add github:Fish121380/auto-mouse

Any plugin you install runs third-party code with your own permissions — it can read your files, use your credentials, and reach the network, and tool approvals don’t sandbox it. GitHub-sourced plugins also run build scripts at install time — pnpm blocks those until you allow them, so an install can stop with ERR_PNPM_GIT_DEP_PREPARE_NOT_ALLOWED or ERR_PNPM_IGNORED_BUILDS; dsh prints the exact key to add under allowBuilds in your profile’s pnpm-workspace.yaml, and the install works on the next run. Allowing a build is a trust decision: only install sources you trust, and pin a commit (github:owner/repo#sha).

README

中文 README

This repository provides Little Mouse Pointer, a Windows desktop UI context picker for AI agents. Select windows, UI elements, or screen regions with hover highlighting, UI Automation, screenshots, and local OCR, then provide the user-approved context to OpenAI Codex, DeepSeek Harness, or another MCP-compatible client over MCP.

The plugin lives in plugins/little-mouse-pointer. See the plugin README for full feature, protocol, and runtime documentation.

Documentation

Install from GitHub in Codex

Run the following commands in PowerShell, replacing OWNER/REPOSITORY with the GitHub repository:

codex plugin marketplace add OWNER/REPOSITORY --ref main
codex plugin add little-mouse-pointer@auto-mouse

For a direct plugin installation, use the GitHub release zip or install the plugins/little-mouse-pointer directory. Do not use the repository root as the direct plugin root.

Connect to DeepSeek Harness

Follow the English installation checklist and DeepSeek Harness configuration, replacing paths with the actual installation directory. MCP stdio must start:

plugins/little-mouse-pointer/app/MousePointer.Windows.exe

Do not use run.ps1 as the MCP stdio bridge; it is for manually starting the GUI and running self-test.

Install the Harness bundle from GitHub

The repository root also provides a dsh.bundle package for direct Harness installation. Pin a release tag:

dsh plugin --profile demo add github:Fish121380/auto-mouse#v0.1.1
dsh --profile demo --dump-config

The bundle locates the Windows x64 executable shipped inside itself and registers @deepseek-ai/dsh-mcp-client. It is Windows x64 only. Override the port in the profile's cordis.patch.yml when needed:

- replace:
    - id: little-mouse-pointer
      config:
        port: 49154

Preflight checklist

  • Windows 10/11 x64.
  • No .NET installation is required; the release is self-contained.
  • Keep every file under plugins/little-mouse-pointer/app.
  • The default port is 49153; the endpoint and MOUSE_POINTER_HTTP_PORT must match.
  • Close older Little Mouse Pointer instances before starting Codex or Harness.
  • MCP tools are ui_context_pick, ui_context_current, and ui_context_clear.
