Fiber AI — Claude Code MCP server: features and setup
Fiber AI gives an AI agent tools to find companies and enrich contacts. Use the MCP server to run those requests from an IDE or chat.
claude mcp add --transport http mcp https://mcp.fiber.ai/mcp/v2/What Fiber AI 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.
