01 · Install Nexus Legal

before you install - you'll need

NEXUS_API_KEY

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add djtellado-nexus-legal-mcp --transport http https://legal.nexusquantum.legal/api/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "djtellado-nexus-legal-mcp": {
      "url": "https://legal.nexusquantum.legal/api/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

endpoint auth requires authentication - rejected our unauthenticated MCP initialize

npm package @nexus-legal/mcp - the @nexus-legal scope differs from the repo owner (djtellado); confirm it's the project's official package

registry namespace io.github.djtellado is GitHub-verified and matches the repo owner
