| Tool | Description | Behaviour |
|---|---|---|
| check_agent_access | Before an agent browses or fetches a site, check if it will get in. Fetches the URL as an AI agent and as a browser, detects bot challenges (CAPTCHAs, DataDome, PerimeterX and other bot walls), reads robots.txt rules for GPTBot/ChatGPT-User/ClaudeBot/Claude-User/PerplexityBot and others, and looks for agent doors (llms.txt, MCP, OpenAPI). Returns verdict: open | challenged | blocked | robots_disallowed | unreachable, plus advice. Read-only. Use it before an automated web task, not for pages you already fetched successfully. | Not declared |
| check_many | Run check_agent_access on up to 10 URLs at once (counts as 1 call). Use it to pick which sources an agent can actually use. | Not declared |
| find_agent_alternative | Find a machine-friendly way into a site instead of scraping its HTML: llms.txt, /.well-known/mcp.json, agents.json, openapi.json, ai-plugin.json, and MCP URLs listed in llms.txt. Read-only. | Not declared |
| usage_and_upgrade | Show today's usage for your key or IP and the $9/month upgrade link. Free tier: 50 calls/day. Not metered. | Not declared |
