Add Tool to kond

You are helping the user add a tool or integration to their running kond server.

How to add tools

There are three ways to add tools to kond:

MCP servers (proxied over REST):

kond mcp add <name> -- <command> [args...]

CLI tools (any command-line program):

kond wrap cli
# Or non-interactively by editing kon.config.json

Scripts (shell scripts, Python scripts, etc.):

kond wrap script

After adding, verify with kond status to confirm the tool is registered.

Popular integrations

When the user asks to add one of these, use the exact commands below:

agent-browser (web browsing for Claude)

agent-browser gives Claude a headless browser it can control from your machine.

Install:

npm install -g agent-browser
agent-browser install

Add to kond as a CLI tool by editing kon.config.json — add this to the tools array:

{
  "type": "cli",
  "name": "browser",
  "command": "agent-browser",
  "description": "Control a headless browser. Commands: open <url>, snapshot, click/fill/type <selector>, screenshot, get text/html/url/title, find role/text/label <query>, eval <js>, close. Use 'snapshot' after navigation to see the page as an accessibility tree with element refs.",
  "allowedSubcommands": ["open", "snapshot", "click", "fill", "type", "hover", "screenshot", "pdf", "get", "find", "wait", "eval", "close", "install"]
}

Then restart: kond restart

Skill context — if the user wants Claude (in code exec) to know how to use agent-browser effectively, the agent-browser skill can be added to the kon skill file. Run npx skills add vercel-labs/agent-browser in the project to get the skill markdown.

Obsidian (notes and knowledge base)

kond mcp add obsidian -- npx -y @mauricio.wolff/mcp-obsidian@latest ~/path/to/vault

Replace ~/path/to/vault with the actual vault path. Find it with:

ls ~/Documents/ | grep -i vault  # common location
ls ~/Library/Mobile\ Documents/iCloud~md~obsidian/Documents/  # iCloud sync

GitHub

kond mcp add github -- npx -y @modelcontextprotocol/server-github

Requires a GITHUB_TOKEN. If the user has one:

kond mcp add github -- npx -y @modelcontextprotocol/server-github --env GITHUB_TOKEN=<token>

Filesystem (additional paths)

kond mcp add filesystem -- npx -y @modelcontextprotocol/server-filesystem /path/to/dir

Or edit the existing read/write builtin tool's allowedPaths in kon.config.json.

Docker

{
  "type": "cli",
  "name": "docker",
  "command": "docker",
  "description": "Docker container management",
  "allowedSubcommands": ["ps", "images", "logs", "inspect", "stats", "exec", "run", "stop", "start", "rm", "build", "pull", "push", "compose"]
}

kubectl

{
  "type": "cli",
  "name": "kubectl",
  "command": "kubectl",
  "description": "Kubernetes cluster management",
  "allowedSubcommands": ["get", "describe", "logs", "exec", "apply", "delete", "scale", "rollout", "port-forward", "top"]
}

ffmpeg

{
  "type": "cli",
  "name": "ffmpeg",
  "command": "ffmpeg",
  "description": "Audio/video processing and conversion"
}

Import from Claude Desktop

If the user has MCP servers configured in Claude Desktop:

# macOS
cat ~/Library/Application\ Support/Claude/claude_desktop_config.json | jq '.mcpServers'

Read the config, then add each server with kond mcp add.

Workflow

Check the server is running: kond status
Identify what the user wants to add
Use the appropriate method above
Verify it was added: kond status
If the user is connected to kon, mention they may need to regenerate their skill file with kond pair for the new tool to appear in Claude's sandbox
