webcmd-mcp

MCP server for Webcmd. Drop one entry into any agent's MCP config and it can drive websites locally — no start.md fetch, no skill files copied into the repo, no per-harness onboarding.

Install

Nothing to install ahead of time. webcmd_setup installs and doctors the CLI on first call.

Claude Code

claude mcp add webcmd -- npx -y @agentrhq/webcmd-mcp

Cursor / Windsurf / VS Code / anything using mcpServers

{
  "mcpServers": {
    "webcmd": { "command": "npx", "args": ["-y", "@agentrhq/webcmd-mcp"] }
  }
}

Codex CLI (~/.codex/config.toml)

[mcp_servers.webcmd]
command = "npx"
args = ["-y", "@agentrhq/webcmd-mcp"]

OpenCode (opencode.json)

{
  "mcp": {
    "webcmd": { "type": "local", "command": ["npx", "-y", "@agentrhq/webcmd-mcp"], "enabled": true }

Tools

Tool

Use

webcmd_setup

Once per machine: install/update webcmd, run doctor, return the usage skill.

webcmd_skill

Read a bundled skill (webcmd-usage, webcmd-browser, webcmd-adapter-author, webcmd-autofix, …). No name → list them.

webcmd_run

Run any webcmd argv, e.g. ["list"], ["web","fetch-browser","https://news.ycombinator.com"].

Skills are read from ~/.webcmd/skills (override with WEBCMD_SKILLS_DIR).

Test

npm install && npm test

Covers the exec helper (exit codes, stderr, missing binary, timeout), output clipping, and a real stdio round-trip against the live webcmd CLI.
