- Metadata Inspection — Retrieve full metadata for datasets and individual resources (files) to understand data structures.
- Organizational Mapping — List all city departments and organizations that provide public data.
- Thematic Exploration — Browse data by groups (e.g., 'Saúde', 'Educação') or tags to find relevant information quickly.
- Resource Access — Get direct links and metadata for CSVs, PDFs, and APIs hosted on the portal.
How it works
- Subscribe to this server
- Enter your Campinas Portal API Key (optional for public data, required for restricted access)
- Start querying city data from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Researchers & Academics — quickly find datasets for urban studies or public policy analysis.
