cl-eli-mcp

MCP server for Chilean legislation via the BCN (Biblioteca del Congreso Nacional de Chile) Linked Open Data SPARQL endpoint. Searches and fetches laws, decrees, and resolutions by their persistent resource URI.

What this is not

BCN's resource URIs are not formally called ELI, but they carry the same idea: jurisdiction, type, issuing body, date, number, all in one dereferenceable URI. This connector returns metadata (title, number, dates, issuing body) - not the operative text of the law. Following source_url (the same URI, content-negotiated) takes you to the human-readable page.

Tools

Tool	Purpose
cl_search_norms	Full-text search over norm titles
cl_get_norm	Full detail for one norm by its BCN resource URI

Every response carries lex_uri and source_url (both the BCN resource URI) and human_readable_citation (e.g. "Ley 18290, de 1984-01-23").
