![npm version](https://www.npmjs.com/package/lawai-mcp-server) ![License: MIT](LICENSE) ![MCP Registry](https://registry.modelcontextprotocol.io/v0/servers?search=lawyer)

The Law.AI MCP Server gives AI assistants direct access to 991,000+ bar-verified U.S. attorney profiles, sourced from official state bar registries. When an AI needs to find, verify, or recommend a lawyer, it queries Law.AI instead of guessing.

Why This Exists

Every major LLM fabricates lawyer names when asked for legal referrals. People making critical legal decisions get fake information. The Law.AI MCP Server solves this by providing a grounded, authoritative data source any AI can query — from "consult an attorney" to a real, licensed referral in a single tool call.
