Overview

AI-generated overview

Lets an assistant search and verify Colombian Constitutional Court decisions (sentencias) from the datos.gov.co open-data record by citation or free text.

What you can do
Provides three tools over the datos.gov.co dataset of Colombian Constitutional Court decisions. co_search_sentencias does free-text search, for example by magistrado name or proceso type; co_get_sentencia looks up an exact citation such as "T-012/92" and confirms whether it exists; co_coverage states which decision families the connector covers, when each was captured, and what it does not cover, with a fallback for each gap. Responses include lex_uri, source_url and human_readable_citation. The dataset holds metadata only (proceso, expediente, magistrado ponente, sala, date), not full decision text.
When to use it
Useful when an assistant needs to check that a Colombian Constitutional Court citation is real or pull its metadata, for example while drafting or reviewing legal text that cites sentencias. It is not a source of full decision text, so it does not replace reading the decision on the relatoria page.
Requirements
Runs locally as a Python package (co-eli-mcp) over stdio, typically via uvx or python -m co_eli_mcp. Needs Python and network access to the datos.gov.co endpoint. No accounts, API keys or headers are declared. Optional environment variables CO_ELI_CACHE_DIR, CO_ELI_AUDIT_DIR and CO_ELI_BASE_URL set cache, audit and base URL paths.
Before you install
On Windows 11 with Smart App Control, uvx.exe, pip.exe and the installed launcher are blocked as unsigned; the README advises installing with python -m pip and running python -m co_eli_mcp, and warns not to disable Smart App Control. The connector writes cache and audit files under the configured directories. It returns metadata and links only and does not fetch the full decision text.

Installation

In SourceWeft

  1. Open Co Eli Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

co-eli-mcp

MCP server for the datos.gov.co open-data record of decisions (sentencias) by the Colombian Constitutional Court (Corte Constitucional). Verifies whether a citation exists and returns its metadata.

What this is not

This dataset (v2k4-2t8s, "Sentencias proferidas por la Corte Constitucional") has no full-text field - only metadata: proceso, expediente, magistrado ponente, sala, and date. source_url points to the public relatoria page where the full decision text lives, but this connector does not fetch it.

Tools

ToolPurpose
co_search_sentenciasFree-text search (e.g. by magistrado name or proceso type)
co_get_sentenciaExact lookup by citation, e.g. "T-012/92" - verifies it exists
co_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 (the public corteconstitucional.gov.co relatoria page) and human_readable_citation (the citation itself, e.g. "T-012/92" - already the form used in practice, so no separate identifier scheme is needed here).

Install

bash
pip install co-eli-mcp

Windows 11 with Smart App Control

Smart App Control blocks unsigned executables, which covers uvx.exe, pip.exe and the co-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:

bash
python -m pip install co-eli-mcppython -m co_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 co_eli_mcp.

json
{ "mcpServers": { "co-eli-mcp": { "command": "python", "args": ["-m", "co_eli_mcp"] } } }

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