menjometre-mcp

Menjometre over the Model Context Protocol. Give any MCP-compatible LLM client read-only access to the Catalan public grants & contracts observatory.

Menjometre is an independent observatory of Catalan public spending. It tracks:

• ~19.5 M RAISC grant records (2016–present)
• ~1.7 M public procurement contracts from Dades Obertes de Catalunya
• ~496 K beneficiary entities with normalised identities
• A statistical Menjometre score flagging concentration and recurrence patterns
• A public-figure graph linking Parlament deputies, Generalitat officials, and board members of public entities

This package is a thin stdio proxy. It forwards MCP requests to the hosted HTTP server at https://www.menjometre.cat/mcp and streams the responses back. It holds no dataset, no credentials, and no per-user state.

Install & use

Zero-install, via npx from any MCP client config:

{
  "mcpServers": {
    "menjometre": {
      "command": "npx",
      "args": ["-y", "menjometre-mcp"]
    }
  }
}

Works in Claude Desktop, Claude Code, Cursor, Zed, Windsurf, Continue, and any other client that speaks the Model Context Protocol over stdio.

Or install globally:

npm install -g menjometre-mcp
menjometre-mcp

Example prompts

Once connected, ask your LLM things like:

• "Which ten Catalan entities received the most RAISC funds in 2024?"
• "Show me the concentration profile of a specific entity by CIF."
• "Which grant-giving bodies award the largest share of their budget to a single beneficiary?"
• "What percentage of a specific municipality's contracts are sole-source?"
• "Explain how the Menjometre score is computed."

The server ships 48 tools across seven domains: entities, grants, contractes, organs, xarxa (public-figure graph), pressupostos, and meta (methodology and attribution).

Data licence & attribution

Every tool response includes a sources array citing the upstream dataset, licence, and publisher. The main sources are:

• RAISC — Registre d'Ajuts i Subvencions de Catalunya (Generalitat de Catalunya, Llei 37/2007 de reutilització)
• Dades Obertes de Catalunya — CC BY 4.0
• BDNS — Base de Datos Nacional de Subvenciones (historical, deprecated)
• Registre d'Entitats Jurídiques de Catalunya
• DOGC — Diari Oficial de la Generalitat de Catalunya
• Portal de la Transparència de Catalunya

Reuse of the data must preserve attribution. When a response includes scored entities, clients must also preserve the accompanying score_meta block — it carries the score scale, a not_an_accusation disclaimer, and a link to the methodology.

Legal envelope

Every response is wrapped in a five-layer envelope designed around Spanish civil rights law (LO 1/1982), the GDPR, and the Catalan public-sector reuse regime:

• L1 transparency — get_methodology returns the full server identity, version, and methodology URL
• L2 attribution — every success envelope includes sources
• L3 data minimisation — explicit field allow-lists at the database layer; no tool returns more than it needs
• L4 personal-data scope — public-figure predicates enforced at the database query, not client-side
• L5 framing — every scored response embeds score_meta with scale, meaning, and a not_an_accusation disclaimer, and uses neutral statistical language ("top decile", "around the median")

Self-hosted / private deployments

Point the proxy at a private deployment:

MENJOMETRE_MCP_URL=https://mcp.example.internal/mcp \
MENJOMETRE_MCP_KEY=your-bearer-token \
npx -y menjometre-mcp

• MENJOMETRE_MCP_URL — upstream Streamable HTTP endpoint (default: https://www.menjometre.cat/mcp)
• MENJOMETRE_MCP_KEY — optional bearer token for gated deployments

Licence

AGPL-3.0-or-later. The proxy is intentionally tiny (~100 lines) so it can be audited in a minute.
