Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

PYPI package cl-eli-mcp

claude mcp add cl-eli-mcp -- uvx cl-eli-mcp==0.3.3

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

ToolPurpose
cl_search_normsFull-text search over norm titles
cl_get_normFull detail for one norm by its BCN resource URI
cl_coverageDeclare what this connector covers, when each family was captured, and - explicitly - what it does NOT cover. Every gap carries a fallback.

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").

Install

pip install cl-eli-mcp
Windows 11 with Smart App Control

Smart App Control blocks unsigned executables, which covers uvx.exe, pip.exe and the cl-eli-mcp.exe launcher that pip writes at install time. The python.exe and py.exe from the python.org installer are signed by the Python Software Foundation, so running the module through the interpreter works:

python -m pip install cl-eli-mcp
python -m cl_eli_mcp

pip.exe is blocked for the same reason, so install with python -m pip, not pip install. If python is not on PATH, use the Windows launcher: py -3 -m cl_eli_mcp.

{ "mcpServers": { "cl-eli-mcp": { "command": "python", "args": ["-m", "cl_eli_mcp"] } } }

Do not turn Smart App Control off to work around this - it cannot be re-enabled without reinstalling Windows.
