Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

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

Run this in your terminal

claude mcp add es-eli -- uvx es-eli-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

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

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {

Common questions

Is Es Eli MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.5.3) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

es-eli-mcp

Install (one command)

As a Claude plugin (Claude Code or the desktop app, needs uv); see plugin/README.md for what it sends and stores:

/plugin marketplace add matematicsolutions/es-eli-mcp

/plugin install es-eli-mcp@es-eli-mcp

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 es_eli_mcp.

{ "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:

BOE (Boletin Oficial del Estado) open-data API - consolidated legislation. Given a BOE id or a date in the official gazette, returns metadata, structure and full consolidated text, with verifiable ELI identifiers and Spanish citations.
Tribunal Constitucional (Sistema HJ / hj.tribunalconstitucional.es) - Spain's 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.
DGT (Direccion General de Tributos, petete.tributos.hacienda.gob.es) - binding tax 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").
TEAC (Tribunales Economico-Administrativos, DYCTEA) - ~6,500 doctrine criterios with the full resolution text inline, searched by RG claim-number segments and/or date range.
AEPD (Agencia Espanola de Proteccion de Datos) - ~46,800 data-protection resolutions with Solr full-text search and a verified PDF permalink per expediente (e.g. "PS-00615-2025").

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 es_browse_gazette (by date) or a known BOE id / ELI; TC rulings

via es_search_constitutional; 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.

The tools

Tool	What it does
`es_browse_gazette`	List documents published in the BOE on a date (`YYYYMMDD`) - discovery.
`es_get_act`	Metadata for a BOE id (eli_uri, official `titulo`, source).
`es_get_index`	The block index (articles, titles) of a consolidated law.
`es_get_text`	Consolidated text (XML), whole or by block.
`es_get_constitutional_ruling`	Tribunal Constitucional ruling by internal resolution id.
`es_search_constitutional`	Resolve a citation (numero+anno, e.g. 31/2010) to the full TC ruling.
`es_search_tax_rulings`	Full-text/date search over DGT consultas (vinculantes or generales).
`es_get_tax_ruling`	Full DGT ruling (facts, question, normativa, answer) by NUM-CONSULTA.
`es_search_teac_doctrine`	TEAC criterios by RG segments and/or resolution-date range.
`es_get_teac_criterio`	Full TEAC criterio + resolution text by DYCTEA id.
`es_search_aepd_resolutions`	Full-text/date search over AEPD resolutions.
`es_get_aepd_resolution`	AEPD resolution + verified full-text PDF permalink by expediente.
`es_coverage`	Declare what this connector covers, when each family was captured, and - explicitly - what it does NOT cover. Every gap carries a fallback.

Every BOE response carries the contract: eli_uri (a full ELI URL, e.g. https://www.boe.es/eli/es/lo/2018/12/05/3), human_readable_citation (the official titulo), and source_url.

Every Tribunal Constitucional response carries: ecli (e.g. ECLI:ES:TC:2010:31 - TC case law has no ELI, ELI covers legislation only), human_readable_citation (Spanish doctrinal convention, e.g. "STC 31/2010, de 28 de junio"), and source_url.

ES_ELI_AUDIT_DIR - default ~/.matematic/audit

No API key. All five sources are keyless.

Governance

Public data only - read-only against the five official sources; no client data leaves the machine.
Audit log - every tool call appends one JSON line to ~/.matematic/audit/es-eli-mcp.jsonl.
Network - the server talks to the official *.boe.es / *.tribunalconstitucional.es / *.hacienda.gob.es / *.aepd.es hosts and the local filesystem. Once, on first use, it also fetches a small configuration file (es-runtime.json.gz, updated source addresses) from this repository's GitHub Releases. That request carries no query content; GitHub's download counter for the file is the only usage signal we see. ES_ELI_RUNTIME_URL="" turns it off; the Claude plugin ships with it off. No LLM provider, no other telemetry.
Verifiable citations - every response is independently checkable via source_url.

See CONSTITUTION.md and DISCOVERY.md.
