Cl Eli MCP server

cl-eli-mcp

<!-- mcp-name: io.github.matematicsolutions/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

Every response carries lexuri and sourceurl (both the BCN resource URI) and humanreadablecitation (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 clelimcp.

{ "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.
