About cl-eli-mcp

cl-eli-mcp provides metadata for Chilean legislation through the BCN Linked Open Data SPARQL endpoint. It supports title searches and lookup by persistent resource URI, with citations and links to human-readable pages rather than operative legal text.

Key features

  1. 01Search norm titles
  2. 02Retrieve norm details by BCN URI
  3. 03Metadata on number, dates, and issuing body
  4. 04Coverage and gap reporting
  5. 05Source URI and readable citations

Use cases

  1. 01Search Chilean norms by title
  2. 02Retrieve a norm using its resource URI
  3. 03Open the linked human-readable source page

MCP support

Exposes tools to MCP clients for searching norm titles, retrieving norm metadata, and checking coverage. Responses include the BCN resource URI and a human-readable citation; operative legal text is not returned.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
  "mcpServers": {
    "matematicsolutions-cl-eli": {
      "command": "uvx",
      "args": [
        "cl-eli-mcp"
      ]
    }
  }
}
Run commanduvx cl-eli-mcp

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Details

From the project README

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.

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
