Lexiel MCP MCP server

Lexiel's official MCP server allows AI assistants to access verified Spanish legal resources, including case law, legislation, and BOE citations. It enables agents to search jurisprudence, verify legal citations against official sources like CENDOJ and TJUE, and assist with legal document drafting and case management without hallucinations.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http lexiel-mcp https://mcp.lexiel.ai

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add lexiel-mcp --url https://mcp.lexiel.ai

Cursor

Merge this server into .cursor/mcp.json in your project, then enable lexiel-mcp in your MCP settings.

  "mcpServers": {
    "lexiel-mcp": {
      "url": "https://mcp.lexiel.ai"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

Cline configuration

{
  "mcpServers": {
    "lexiel-mcp": {
      "type": "streamableHttp",
      "url": "https://mcp.lexiel.ai",
