# Optifeed Radar > Open-source AI brand and product visibility. Radar asks real AI engines real buyer questions, measures whether a brand or supplied products are recommended, and preserves the evidence behind the result. Optifeed Radar runs locally, uses the user's own provider API keys, and stores snapshots on the user's machine. It supports OpenAI, Anthropic Claude, Google Gemini, and Perplexity. Scores are point-in-time estimates from sampled answers and vary between runs. ## Start here - [Product overview](https://radar.optifeed.com/) - [Install the Agent Skill](https://radar.optifeed.com/skills/) - [Use Radar from an AI agent](https://radar.optifeed.com/agents/) - [MCP server](https://radar.optifeed.com/mcp/) - [Command-line interface](https://radar.optifeed.com/cli/) - [Use Radar with Codex](https://radar.optifeed.com/codex/) - [Use Radar with Claude Code](https://radar.optifeed.com/claude-code/) - [Apple demonstration](https://radar.optifeed.com/examples/apple/) - [Full machine-readable context](https://radar.optifeed.com/llms-full.txt) ## Markdown documentation - [CLI documentation](https://radar.optifeed.com/docs/cli.md) - [Agent Skill documentation](https://radar.optifeed.com/docs/skills.md) - [MCP documentation](https://radar.optifeed.com/docs/mcp.md) - [Codex setup](https://radar.optifeed.com/docs/codex.md) - [Claude Code setup](https://radar.optifeed.com/docs/claude-code.md) - [Methodology summary](https://radar.optifeed.com/docs/methodology.md) - [Apple example report](https://radar.optifeed.com/examples/apple/report.md) - [Apple example JSON](https://radar.optifeed.com/examples/apple/report.json) ## Project - [GitHub repository](https://github.com/optifeed/optifeed-radar) - [npm package](https://www.npmjs.com/package/optifeed-radar) - [Skills.sh listing](https://skills.sh/optifeed/optifeed-radar/optifeed-radar) - [MCP discovery](https://radar.optifeed.com/.well-known/mcp.json) - [Agent skill discovery](https://radar.optifeed.com/.well-known/agent-skills/index.json) - [Optifeed](https://www.optifeed.com/) ## Primary commands - Agent Skill: `npx skills add optifeed/optifeed-radar --skill optifeed-radar -g` - Claude plugin: `/plugin marketplace add https://github.com/optifeed/optifeed-radar.git`, then `/plugin install optifeed-radar@optifeed` - Free audit: `npx optifeed-radar audit yourbrand.com` - Brand visibility: `npx optifeed-radar check yourbrand.com --quick --max-cost 0.20 --yes` - Product visibility: `npx optifeed-radar shopping yourbrand.com --products "Product A, Product B" --yes` - MCP executable: `npx -y --package=optifeed-radar@0.2.3 optifeed-mcp` Verified public release: `optifeed-radar@0.2.3`.
