mcp-cli-tools

MCP server that gives AI coding agents (Claude Code, Cursor, Cline, etc.) access to multiple AI models through Antigravity CLI and OpenAI Codex CLI.

Think of it as a local Fugu-style orchestrator — your AI agent can consult Gemini, GPT, and other models mid-conversation without leaving the editor.

What it does

Your AI agent gains the ability to:

• Get a second opinion from a different model family

• Run code reviews via Codex without leaving the conversation

• Do adversarial verification (one model checks another's work)

• Route by expertise — Gemini for analysis, GPT for code review

Prerequisites

• Antigravity CLI installed as agy

• OpenAI Codex CLI installed as codex

• Node.js 18+

Install

git clone https://github.com/Marcelo-Henry/mcp-cli-tools.git
cd mcp-cli-tools
npm install
npm run build

Configure in Claude Code

Add to ~/.claude/settings.json under mcpServers:

{
  "mcpServers": {
    "cli-tools": {
      "command": "node",
      "args": ["/path/to/mcp-cli-tools/dist/index.js"]
    }
  }
}

Usage

run_antigravity

Query any model available in Antigravity CLI:

run_antigravity(promptContext: "Analyze this architecture", model: "gemini-3.1-pro")

List available models:

run_antigravity(subcommand: "models")

Run subcommands:

run_antigravity(subcommand: "help")
run_antigravity(subcommand: "plugin", args: ["list"])

run_codex

Review uncommitted changes:

run_codex(action: "review", flags: ["--uncommitted"])

Review with a specific prompt:

run_codex(action: "review", prompt: "Focus on security vulnerabilities")

Review against a branch:

run_codex(action: "review", flags: ["--base", "main"])

Use a specific model:

run_codex(action: "review", prompt: "Audit this code", model: "gpt-5.5")

Note: prompt and flags (--uncommitted, --base) are mutually exclusive in Codex CLI.

Available Models

Via Antigravity

Via Codex

Making your AI agent orchestrate automatically

Add orchestration rules to your global ~/.claude/CLAUDE.md to make Claude Code call these tools proactively. See ORCHESTRATION.md for a full guide with triggers and patterns.
