What API formats are supported?

REST APIs with a discoverable schema (OpenAPI/Swagger) and MCP-compatible servers are both supported. Plain REST endpoints without a schema require manual tool definition.

Can I limit who can use a custom integration?

Private integrations are only accessible to your account. Published integrations are visible to all GAIA users on the marketplace.

How many custom integrations can I create?

There is no hard limit on the number of custom integrations per account. Each integration's tools count toward the total tool limit available to GAIA in a single conversation.

How it works

Three steps to get started.

Set up in minutes. Works automatically from there.

Enter the endpoint URL and auth

Paste the URL of any REST API or MCP server and add a bearer token or configure OAuth.

GAIA discovers the available tools

The integration is crawled and its endpoints are auto-indexed as callable tools for GAIA's agents.

Use in chat, workflows, or publish

Tools are live immediately in conversations and workflows. Toggle public to share on the marketplace.

Use cases

How teams use this.

Real workflows, real outcomes.

Internal ticket system integration

An ops team points GAIA at their Zendesk-alternative's REST API, adds a bearer token, and immediately gains the ability to query and create tickets from chat.

Proprietary analytics API in workflows

A data analyst connects an internal analytics API to GAIA and builds a weekly workflow that fetches KPIs and formats them into a Slack summary automatically.

Shared integration across a team

A developer builds a custom integration for a niche project management tool, publishes it to the marketplace, and lets the whole team install it with one click.
