MCP Self-Service
Connect Claude directly to your Pclika hardware via the MCP channel — one command setup.

For real-time status updates follow GitHub Releases. Critical issues are announced there first.
MCP Self-Service
Quick Connect
Run three commands and Claude (or Cursor / VS Code) will have live access to your Pclika hardware.
1. Install bridge
pip install pclika-bridge
2. Start SSE server
pclika-bridge --port /dev/ttyUSB0 --serve # default: localhost:3141
3. Register with Claude Code
claude mcp add pclikaPlatform --transport sse http://localhost:3141/sse
After registration, restart Claude Code. The pclikaPlatform MCP server will appear in the tool list —
type "read temperature sensor" and Claude talks to your hardware directly.
Self-Service
FAQ
Bridge can't find serial port
On Linux add your user to the
dialout group: sudo usermod -aG dialout $USER then log out and back in.
On macOS the port is typically /dev/tty.usbserial-* — run ls /dev/tty.* to find it.
On Windows use Device Manager → Ports (COM & LPT) to identify the COM port, then pass --port COM3.
Claude doesn't see the pclikaPlatform MCP tools
Make sure the SSE server is running first (
pclika-bridge --serve), then restart Claude Code after running claude mcp add.
You can verify registration with claude mcp list. If the server is listed but tools don't appear, check that http://localhost:3141/sse is reachable in your browser.
Firmware flash fails or board not detected
Hold the BOOT button on the ESP32-S3 while connecting USB, then run
idf.py flash.
If esptool.py still times out, try a different USB cable (data-capable, not charge-only) and a direct port on your machine — USB hubs can cause issues.
sensor_read returns "timeout" or stale data
Check the sensor wiring against the schematic in Downloads → Schematics.
The I²C bus needs pull-up resistors (4.7 kΩ to 3.3 V). Run
sensor_read(sensor_id="ping") first — if that times out the bridge–board serial link itself has an issue.
How do I update the firmware without re-flashing everything?
Use OTA mode: run
pclika-bridge ota --version latest while the board is connected via serial.
The bridge downloads the latest release from GitHub Releases, verifies the SHA-256 checksum, and writes only the app partition.
Total downtime is under 30 seconds.
Can I use Pclika with Cursor or VS Code instead of Claude Code?
Yes. Download the config file for your editor above, merge it into your editor's MCP settings JSON, and start the SSE server.
Cursor uses
.cursor/mcp.json; VS Code (with the MCP extension) uses .vscode/mcp.json.
The MCP protocol is editor-agnostic.
Where are the Developer Guide PDFs in other languages?
Go to Downloads → Developer Guides.
PDFs are available in English, 中文, Русский, Français, and Deutsch — all downloadable from GitHub Releases.

Before You Report
Run these commands and include the output in your GitHub Issue or email — it cuts resolution time significantly.
# Bridge version and serial port scan
pclika-bridge --version
pclika-bridge --list-ports
# Test connection to board
pclika-bridge --port /dev/ttyUSB0 --ping
# MCP registration check (Claude Code)
claude mcp list
# Python environment
python --version
pip show pclika-bridge
