Little Mouse Pointer

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

• Getting started tutorial: installation, first selection, and common problems.
• Beginner installation checklist: verify Codex, DeepSeek Harness, and manual-run setups step by step.
• Complete plugin README: features, user flow, privacy limits, and known boundaries.
• Runtime notes: the self-contained runtime, run.ps1, and MCP stdio behavior.
• DeepSeek Harness configuration: manual Cordis configuration when the bundle is unavailable.
• Protocol reference: tool output fields and the approval flow.

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.
