Tools the agent gets

scrape · search · map · crawl + crawl_status · seo_audit · list_collectors · run_collector · collector_run_status

Prompts that work

• "Map quanticdata.io, then read the five newest blog posts and summarise the themes."
• "Search serp api pricing in the US and Germany and tell me how the top ten differ."
• "Is our pricing page indexable without JavaScript?"
• "Use list_collectors, then pull 40 dental clinics in Austin with local_business_leads."

Let the agent read the catalogue before it picks a collector — the schemas are published so a model can choose correctly.

Background: how MCP servers work · is an MCP server like an API?
