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").
