Es Eli MCP server

es-eli-mcp

<!-- mcp-name: io.github.matematicsolutions/es-eli-mcp -->

Install (one command)

Published on PyPI + MCP Registry (io.github.matematicsolutions/es-eli-mcp). Run without cloning:

uvx es-eli-mcp

Configure your MCP client (stdio):

{ "mcpServers": { "es-eli-mcp": { "command": "uvx", "args": ["es-eli-mcp"] } } }

Windows 11 with Smart App Control

Smart App Control blocks unsigned executables, which covers uvx.exe, pip.exe and the es-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 es-eli-mcp
python -m es_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 eselimcp.

{ "mcpServers": { "es-eli-mcp": { "command": "python", "args": ["-m", "es_eli_mcp"] } } }

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

Building from source: see Install.

An MCP server for five Spanish open-data sources:

or a date in the official gazette, returns metadata, structure and full consolidated text, with verifiable ELI identifiers and Spanish citations.

1. BOE (Boletin Oficial del Estado) open-data API - consolidated legislation. Given a BOE id

Constitutional Court case law (Sentencias / Autos / Declaraciones). Given an internal resolution id, or a citation number+year (e.g. "STC 31/2010"), returns the full ruling with ECLI and a Spanish doctrinal citation.

1. Tribunal Constitucional (Sistema HJ / hj.tribunalconstitucional.es) - Spain's

rulings: ~69,500 consultas vinculantes + ~19,700 consultas generales (live-counted 2026-07-08). Full-text/date search plus the full ruling text by NUM-CONSULTA (e.g. "V0001-25").

1. DGT (Direccion General de Tributos, petete.tributos.hacienda.gob.es) - binding tax

full resolution text inline, searched by RG claim-number segments and/or date range.

1. TEAC (Tribunales Economico-Administrativos, DYCTEA) - ~6,500 doctrine criterios with the

with Solr full-text search and a verified PDF permalink per expediente (e.g. "PS-00615-2025").

1. AEPD (Agencia Espanola de Proteccion de Datos) - ~46,800 data-protection resolutions

Part of the MateMatic eu-legal-mcp production line - after PL, DE and AT. Same citation contract pattern, five Spanish sources.

Free-text search exists on DGT and AEPD only. The BOE open-data keyword-search endpoint

(/legislacion-consolidada) currently returns a server-side error; the Tribunal

Constitucional site only supports structured search (citation number+year, ECLI, magistrado,

materia); DYCTEA accepts text-looking parameters but silently ignores them (verified live).

Discover BOE documents via esbrowsegazette (by date) or a known BOE id / ELI; TC rulings

via essearchconstitutional; TEAC criterios via RG segments or dates. Every response

carries a dataset_note.

Licence. Both sources are official public information published as Spanish PSI

(public-sector information) open data; reuse presumes acceptance of the respective reuse

conditions. This connector relays that public content with attribution and a source_url.
