xAI has released Connectors for Grok, enabling users to link Grok to various external tools and data sources. This functionality allows Grok to access information from services like email, cloud storage, and calendars directly within a chat interface. Connectors are available to all Grok users.

For Grok Business and Enterprise users, a team administrator must provision a connector in the cloud console before it becomes accessible to organization members. The Grok 4.6 model, described as xAI's frontier model for coding, agentic tasks, and knowledge work, is available on the xAI API and features a 500k context window, text and image inputs, and no text output limit.

Key Points

  • Connectors allow Grok to access external tools and data sources directly within a conversation.
  • Built-in connectors are maintained by xAI, integrate natively with Grok, and authenticate via OAuth.
  • A catalog of pre-configured OAuth connectors is available for popular third-party services.
  • Users can integrate services not in the catalog by bringing their own Model Context Protocol (MCP) server.
  • MCP is an open standard enabling AI assistants to interact with external tools and data sources through a unified protocol.
  • Grok 4.6 is available on the xAI API with a 500k context window and text/image inputs.
  • Grok Bot, durable AI teammates with messaging, approvals, connectors, and routines, is also available.

Context

According to xAI, built-in connectors authenticate via OAuth, requiring a single sign-in without further configuration. Grok automatically uses a connector's tools when questions relate to that service. For custom integrations, an MCP server must be reachable over the public internet, potentially requiring a tunneling service for local setups. The Grok 4.6 model, released in September, supports reasoning effort levels including low, medium, high (default), and xhigh, with specific pricing tiers based on token count, according to xAI's release notes.

Why It Matters

This capability allows builders to extend Grok's functionality beyond its core model, integrating it with existing data and operational workflows. The support for both pre-built and custom connectors provides flexibility for various integration needs, from common third-party services to internal APIs and databases.

What To Do

  • Browse the full catalog of pre-configured OAuth connectors at grok.com/connectors.
  • For services not in the catalog, consider implementing a custom MCP server.
  • Note that Grok Business and Enterprise users require team admin provisioning for connectors.
  • Review the Grok 4.6 overview for details on its capabilities and pricing.
