BetterCallClaudeMCP

Model Context Protocol (MCP) servers for Swiss legal research.

This repository contains the standalone MCP servers that power the BetterCallClaude Swiss legal intelligence plugin. Each server is a separate, independently-installable package.

This repo is MCP-only. Slash commands, skills, agents, hooks, and the Cowork plugin manifest live in fedec65/bettercallclaude.

Servers

Server	Transport	Purpose
bge-search	stdio	Swiss Federal Supreme Court (BGE/ATF/DTF) decision search
entscheidsuche	stdio	Federal + cantonal court decision search via entscheidsuche.ch
legal-citations	stdio	Validate, parse, format, and convert Swiss legal citations
legal-persona	stdio	Case strategy, drafting, and document analysis tools
tas-jurisprudence	HTTP (Streamable)	TAS/CAS (Court of Arbitration for Sport) decision search

See docs/07-MCP-SERVERS-REFERENCE.md for the full tool reference.

Each directory is a self-contained npm package with its own package.json, tests, and build. The root package.json wires them together as npm workspaces so you can build/test all of them in one pass.

Development

Requires Node.js ≥ 18 and npm ≥ 10.

# Install dependencies for every server
npm install

# Build all servers
npm run build

# Run tests across all servers
npm test

# Typecheck all servers
npm run typecheck

To work on a single server:

cd mcp-servers/bge-search
npm run build
npm test

Using the servers with Claude

Point your MCP-capable client at a built server's entry point. Example for Claude Desktop (~/Library/Application Support/Claude/claude_desktop_config.json on macOS, %APPDATA%\Claude\claude_desktop_config.json on Windows):

{
  "mcpServers": {
    "bge-search": {
      "command": "node",
      "args": ["/absolute/path/to/BetterCallClaudeMCP/mcp-servers/bge-search/dist/index.js"]
    },
    "entscheidsuche": {
      "command": "node",
      "args": ["/absolute/path/to/BetterCallClaudeMCP/mcp-servers/entscheidsuche/dist/index.js"]
    },
    "legal-citations": {
      "command": "node",
      "args": ["/absolute/path/to/BetterCallClaudeMCP/mcp-servers/legal-citations/dist/index.js"]
    },
    "legal-persona": {
      "command": "node",
      "args": ["/absolute/path/to/BetterCallClaudeMCP/mcp-servers/legal-persona/dist/index.js"]
    }
  }
}

tas-jurisprudence exposes a Streamable HTTP endpoint and is intended to be deployed as a service (see mcp-servers/tas-jurisprudence/README.md).
