### Description (declared)

# trace-mcp 
 
A Python MCP server for controlling Android system tracing via a native traceserver binary, supporting device selection and custom port forwarding. Designed for use with the uv/uvx toolchain. 
 
## Prerequisites 
- Python 3.12+ 
- [uv](https://github.com/astral-sh/uv) (for dependency management and running scripts) 
- Android Debug Bridge (adb) in your PATH 
- Android device (API 21+), with USB debugging enabled 
- Prebuilt traceserver binaries in the `bin/` directory for all supported ABIs 
 
## Installation 
```sh 
uv pip install -e . 
``` 
 
## Usage 
 
### Start the MCP server (with uvx) 
```sh 
uvx trace-mcp --port 12345 
``` 
- `--port` (optional): Specify the port for traceserver and forwarding (default: 12345) 
 
### MCP Tool Functions 
All tool functions accept an optional `sn` (device serial number) and `port` argument. 
 
#### 1. begin_trace 
Begin a trace section on the device. 
- Arguments: 
  - `trace_tag` (str): Trace tag name 
  - `sn` (str, optional): Device serial number 
  - `port` (int, optional): Port (default: 8080) 
 
#### 2. end_trace 
End a trace section on the device. 
- Arguments: 
  - `trace_tag` (str): Trace tag name 
  - `sn` (str, optional): Device serial number 
  - `port` (int, optional): Port (default: 8080) 
 
#### 3. trace_test_mode 
Start traceserver in test mode on the device. 
- Arguments: 
  - `sn` (str, optional): Device serial number 
  - `port` (int, optional): Port (default: 8080) 
 
#### 4. stop_traceserver 
Stop the traceserver process and remove port forwarding. 
- Arguments: 
  - `sn` (str, optional): Device serial number 
  - `port` (int, optional): Port (default: 8080) 
 
## Example 
```sh 
uvx trace-mcp --port 9000 
``` 
 
Then, use your MCP client to call the tool functions with the appropriate arguments.
