Gemini CLI (launched 25 Jun 2025) drops Google’s Gemini 2.5 Pro straight into your terminal with a whopping 1 M-token context and free preview limits. 

Codacy AI Guardrails adds an MCP “security copilot” layer on top of any LLM.

Just pop in a token, and it blocks risky suggestions before they hit your repo. 

Quick-start

 

bash

# 1. Install both CLIs

npm i -g @google-gemini/cli @codacy/codacy-mcp

# 2. Auth Codacy once

export CODACY_ACCOUNT_TOKEN=<your-token> # keep it in .zshrc / CI secret store

# 3. Tell Gemini about the MCP

cat <<'EOF' > ~/.gemini/settings.json
{
  "mcpServers": {
    "codacy": {
        "command": "npx",
        "args": [
          "-y",
          "@codacy/codacy-mcp@latest"
        ]
      }
  },
  "contextFileName": "GEMINI.md"
}

EOF

# 4. Test

gemini /mcp desc # should list "Codacy Guardrails"

gemini "/fix vuln in src/auth.ts"

Total wall-clock: ~90 seconds, including copy-paste.

 

Watch it in action
