# EPO Case Law MCP Server (epo-caselaw-mcp)

An open Model Context Protocol (MCP) server, REST API, and web interface analogous to OpenCaseLaw.ch for European Patent Office (EPO) Boards of Appeal (BoA) decisions.

Overview

  • Data Source: Official bi-yearly bulk dataset from the EPO Bulk Data Distribution Service (BDDS Product 14.6: Boards of Appeal decisions). Over 50,000 decisions from 1978 to present.

  • Backend & Protocol: FastAPI application serving both standard REST endpoints (/docs) and MCP Server-Sent Events (SSE) protocol for AI assistants (Claude, Cursor, Antigravity, etc.).

  • Storage & Search: PostgreSQL with pgvector for semantic vector search (Vertex AI multilingual embeddings) and svector for full-text keyword retrieval.

  • Citation Graph: Extracted network of statutory EPC provisions (Articles and Rules) and cross-decision precedent citations (T, J, G, D, R, W decisions).

  • Web UI: Fast server-rendered search interface built with FastAPI, Jinja2, and HTMX.

Project Architecture & Roadmap

This project uses Wayfinder for phased delivery:

  • Streaming XML parser for high-efficiency ingestion of EPO BDDS bulk datasets.

  • Relational schema + vector embedding pipeline.

  • MCP tool suite (search_decisions, get_decision, get_citations, ind_similar, lookup_statute).

  • Cloud Run deployment configuration.

This server cannot be deployed

One endpoint for every MCP toolRayrun runs every MCP server behind one URL and holds the credentials. Each call is decided per client, tool, and argument, then recorded.ray.runAd
