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

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:

python -m pip install co-eli-mcp
python -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.

{ "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.
