Expert Sapiens
For Developers

Build AI agents that find and contact human experts.

Expert Sapiens exposes a native MCP server and REST API so your AI agent can search verified professionals, read full profiles, and send inquiries — all without any user login.

How it works

Three steps. No user login required on the end-user side.

1

Search

Query experts by category, location, language, or keyword. Get back a ranked list with profile and booking URLs.

2

Evaluate

Fetch the full profile — bio, services with pricing, weekly availability, and all public contact channels.

3

Contact

Submit an inquiry on behalf of your user. The expert is notified by email and replies directly — no platform friction.

MCP Quick Start

Add Expert Sapiens as a native tool to Claude, Cursor, Windsurf, or any MCP-compatible host. The MCP server is live at https://expertsapiens.com/api/mcp.

Claude Desktop — read only
// claude_desktop_config.json
{
  "mcpServers": {
    "expert-sapiens": {
      "url": "https://expertsapiens.com/api/mcp"
    }
  }
}
Claude Desktop — with API key
// claude_desktop_config.json — with API key (enables submit_inquiry)
{
  "mcpServers": {
    "expert-sapiens": {
      "url": "https://expertsapiens.com/api/mcp",
      "headers": {
        "Authorization": "Bearer es_live_..."
      }
    }
  }
}
Cursor / Windsurf
// .cursor/mcp.json
{
  "mcpServers": {
    "expert-sapiens": {
      "url": "https://expertsapiens.com/api/mcp",
      "headers": {
        "Authorization": "Bearer es_live_..."
      }
    }
  }
}
stdio bridge (mcp-remote)
// For stdio-only clients — bridges remote MCP via npx
{
  "mcpServers": {
    "expert-sapiens": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://expertsapiens.com/api/mcp"]
    }
  }
}

search_experts and get_expert work without an API key. submit_inquiry requires a Bearer token. Generate a key →
