atlas2-mcp

Python FastMCP server for the atlas2 resolution flow.

Current status

• Exposes one tool: resolve()
• resolve() now performs the working path:
  • store lookup (label/alias)
  • Wikidata fallback using wikidata.reconci.link quick-resolve (single-candidate)
  • minimal persist to Virtuoso via MCP
  • cache hits return the stored result
• Store lookup was debugged and made robust by splitting label-first then alias.
• Maintenance scaffolding (dry-run CLI) exists to upgrade atlas:needsCuration true entities using:
  • ontology/wikidata_subclassof.ttl
  • Wikidata entity dumps
  • Atlas type bucket inference (Person/Organization/Location/etc.)
