# Android MCP Toolkit for AI Agents
Small MCP server with two tools:
- Fast SVG → Android VectorDrawable conversion (cached, file or inline).
- adb logcat reader with package/pid/tag filters for quick crash triage.
## 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.
## 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:
```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.
