## What it does

Fiber AI exposes tools for company search, contact enrichment, and finding email addresses. It comes in three remote server options: V2 offers direct tools for common operations, V3 makes public operations available with browser-based sign-in, and Core uses five tools to discover and call API operations.

V2 and Core require a Fiber AI API key; V3 uses OAuth through a browser. That distinction affects setup: V2 and Core will not connect without a key. In Claude Code, add the server with its command, then complete sign-in separately for V3. Codex can add the server with `codex mcp add`.

Use MCP for tool calls from an IDE or chat. Fiber AI recommends its REST API instead when building an autonomous script or a production pipeline.
