This repository publishes the open-source remote MCP server for the GO2ABROAD Registry — statutory intelligence covering cross-border entity formation, multi-tier taxation, and banking KYC rails across 80+ jurisdictions.

Records are archived under permanent DOIs on Zenodo, Figshare, and Harvard Dataverse, and served from Cloudflare D1 (transcend-go2abroad / dossier_catalog) plus R2 CDN.

Connect the remote MCP server (SSE)

No local dataset install is required. Point Cursor, Claude Desktop, Cline, Dify, LibreChat, or any MCP-compatible client at the edge SSE endpoint.

• SSE endpoint: https://mcp-registry.go2abroad.space/sse

• Messages endpoint: https://mcp-registry.go2abroad.space/messages?sessionId=<id>

• Health JSON: https://mcp-registry.go2abroad.space/

Legacy stdio bridge via mcp-proxy (if your client cannot open remote SSE directly):

    "go2abroad-registry": {
      "command": "npx",
      "args": ["-y", "mcp-proxy", "https://mcp-registry.go2abroad.space/sse"]

• POST /messages?sessionId= — JSON-RPC message channel for legacy SSE clients

• GET / — health / discovery JSON with tools, resources, and registry deep-link
