wisent-wire-mcp 0.4.0

MCP server for the Wisent Wire hardware testing platform

wisent-wire-mcp

MCP (Model Context Protocol) server for the Wisent Wire hardware testing platform. Lets AI assistants interact with WisentWire devices — power control, firmware flashing, and UART communication.

Installation

Requires Python 3.10+. Install with pipx — it puts the MCP server in an isolated environment and adds the wisent-wire-mcp binary to your PATH.

1. Install pipx (one-time)

# macOS
brew install pipx
pipx ensurepath

# Linux / WSL
python3 -m pip install --user pipx
python3 -m pipx ensurepath

Open a new terminal so the updated PATH is picked up.

2. Install the MCP server

pipx install wisent-wire-mcp

Verify:

which wisent-wire-mcp         # ~/.local/bin/wisent-wire-mcp (or similar)

3. Upgrade / uninstall

pipx upgrade   wisent-wire-mcp
pipx uninstall wisent-wire-mcp

Configuration

.mcp.json location

Claude Code reads MCP servers from .mcp.json. Two scopes:

Scope	Path	When to use
Project	<repo-root>/.mcp.json	Shared with the project (checked into VCS or per-repo)
User	~/.claude.json under the mcpServers key	Available in every Claude Code session for this user

Claude Desktop uses a separate file:

Platform	Path
macOS	~/Library/Application Support/Claude/claude_desktop_config.json
Windows	%APPDATA%\Claude\claude_desktop_config.json
Linux	~/.config/Claude/claude_desktop_config.json

Example .mcp.json

{
  "mcpServers": {
    "wisent-wire": {
      "command": "wisent-wire-mcp",
      "env": {
        "WISENT_WIRE_URL": "https://int.wisent-wire.com",
        "WISENT_WIRE_EMAIL": "[e-mail]",
        "WISENT_WIRE_PASSWORD": "..."
      }
    }
  }
}

After editing .mcp.json, restart Claude Code (or reload the window) for the server to be picked up.
