Android MCP Toolkit for AI Agents

Small MCP server with three tools:

• Fast SVG → Android VectorDrawable conversion (cached, file or inline).
• adb logcat reader with package/pid/tag filters for quick crash triage.
• Translation length difference estimator to flag risky length deltas before layout breaks.

Why this exists

The Mission: Bringing Native Android to the AI Agent Era

While the AI ecosystem flourishes with web-first tools, Android development often feels left behind. This MCP server is my answer to that gap—a dedicated bridge connecting AI Agents directly to the Android toolchain.

⚡ Zero-Friction Asset Conversion: Convert SVGs to VectorDrawables instantly without the overhead of launching Android Studio.

🔍 Direct Diagnostic Access: Empower agents to pull, filter, and analyze adb logcat streams (by package, PID, or tag) in real-time.

🤖 Agent-Native Architecture: Deliver structured, scriptable outputs that LLMs can parse and act upon efficiently.

🚀 Built for Extensibility: A solid foundation designed to grow, paving the way for future utilities like bitmap helpers and asset validation.

Pairing ideas

• Figma MCP: grab SVGs from designs, feed to convert-svg-to-android-drawable to get XML for Android resources.
• Debugging: while running the app, call read-adb-logcat with package name or tag to capture crashes and filtered logs without leaving the MCP client.

Previews

SVG to VectorDrawable

• Figma request → SVG extraction
  
• Flag conversion preview (single)
  
• Batch flag review (side-by-side)
  
• Batch run via MCP (console)
  

ADB logcat tool

• Crash capture prompt (inputs + filters)
  
• Response preview (summarized logcat)
  

Current tools

• convert-svg-to-android-drawable

  • Inputs: svg (inline) or svgPath (file path). Optional: outputPath, floatPrecision (default 2), fillBlack (default false), xmlTag (default false), tint, cache (default true).
  • Output: VectorDrawable XML text; also writes to disk when outputPath is provided.
  • Performance: LRU cache (32 entries) keyed by SVG + options plus fast reuse in-session.
  • Converter: vendored fork in vendor/svg2vectordrawable with fixes for rgb()/rgba(), hsl()/hsla(), and named colors. Upstream license: vendor/svg2vectordrawable/LICENSE (MIT).

• read-adb-logcat

  • Inputs: packageName (resolve pid via adb shell pidof -s), pid (explicit), tag, priority (V|D|I|W|E|F|S, default V), maxLines (tail count, default 200, max 2000), timeoutMs (default 5000, max 15000).
  • Behavior: Runs adb logcat -d -t <maxLines> with optional --pid=<pid> and -s tag:priority.
  • Output: Returns the logcat text; if no lines are returned, responds with a short message.
  • Notes: Requires adb available in PATH and a connected device/emulator. Provide at least one of packageName, pid, or tag to scope logs.

• get-pid-by-package

  • Inputs: packageName (required), timeoutMs (default 5000, max 15000).
  • Behavior: Resolves pid via adb shell pidof -s <package>.
  • Notes: Use this first, then pass pid to other logcat tools for noise-free filtering.

• get-current-activity

  • Inputs: timeoutMs (default 5000, max 15000).
  • Behavior: Parses adb shell dumpsys window for mCurrentFocus / mFocusedApp to reveal the currently focused window (useful even in single-activity setups to confirm top window).

• fetch-crash-stacktrace

  • Inputs: packageName (optional, resolves pid), maxLines (default 400, max 2000), timeoutMs (default 5000, max 15000).
  • Behavior: Pulls crash buffer via adb logcat -b crash -d -t <maxLines>; filters by --pid when package is provided.

• check-anr-state

  • Inputs: maxLines (default 400, max 2000), timeoutMs (default 5000, max 15000).
  • Behavior: Fetches ActivityManager:E *:S (recent ANR logs) and best-effort reads /data/anr/traces.txt (stat + tail 200 lines). May require root/debuggable.

• clear-logcat-buffer

  • Inputs: timeoutMs (default 5000, max 15000).
  • Behavior: Runs adb logcat -c to clear buffers before a new scenario.

• estimate-text-length-difference

  • Inputs: sourceText (original), translatedText (to compare), tolerancePercent (default 30, max 500).
  • Behavior: Measures grapheme length of both strings, computes percent change, and reports whether it exceeds the tolerance (useful to catch translation length blowups that could break layouts).

Roadmap (planned)

• Additional MCP tools for Android assets (e.g., batch conversions, validations, optimizers).
• Optional resource prompts for common Android drawables/templates.
• Upcoming MCP utilities (planned):
  • Logcat reader: stream and filter Android logcat output via MCP.
  • Asset checkers: flag common drawable issues (size, alpha, color profile).
  • Batch conversions: multi-SVG to VectorDrawable with consistent options.
  • Template prompts: quick-start drawable/XML snippets for common patterns.

Quick start

• npm install
• npm run build
• node dist/index.js (stdio MCP server)

Run via npx

• Global: npx android-mcp-toolkit

Use in Cursor (MCP config)

Add to your Cursor settings JSON:

{
  "mcpServers": {
    "figma-desktop": {
      "url": "http://127.0.0.1:3845/mcp"
    },
    "android-mcp-toolkit": {
      "command": "npx",
      "args": [
        "-y",
        "android-mcp-toolkit"
      ]
    }
  }
}

The npx call downloads the published package; no local path required.

Quick install via Cursor deep link:

• cursor://anysphere.cursor-deeplink/mcp/install?name=android-mcp-toolkit&config=eyJjb21tYW5kIjoibnB4IC15IGFuZHJvaWQtbWNwLXRvb2xraXQifQ%3D%3D

Examples

• Input SVG: sample_svg.svg
• Output VectorDrawable: examples/sample_svg.xml

Notes

• Transport: stdio via @modelcontextprotocol/sdk.
• Base deps kept minimal; everything needed to convert SVGs is vendored/included.
