meta-data-mcp

As of version 2.5, meta-data-mcp now actually works with Claude Desktop. Previously, a harness limitation in Claude prevented hot-add of mcp-servers (the provider plugins). One MCP server gatekeeping hundreds of tool calls to open data sources across all domains--no API keys required. Ask about GDP, earthquakes, court records, air quality, drug approvals, satellite imagery, or biodiversity — meta-data-mcp routes the request to the right API and returns structured data. Providers activate lazily so the default tool surface stays small; use opendata-find-providers to discover and opendata-activate-provider to unlock domain-specific tools on demand. Run it locally or with streaming sse.
