GitHub Copilot · GitHub's coding agent built into your IDE

Image and voice generation, plugged into GitHub Copilot.

GitHub Copilot supports custom agents and MCP servers in 2026, which means Gathos can be wired in as a callable tool inside any IDE that ships Copilot. The setup is one curl line and one config entry.

Install
curl -sL https://gathos.com/install.sh | bash

Why pair Gathos with GitHub Copilot

01
Copilot custom agents make this trivial
GitHub Copilot Agents (GA in 2026) let you register external tools the agent can invoke. Gathos installs as a custom agent and Copilot picks it up across VSCode, JetBrains, Visual Studio, and the GitHub web UI.
02
One auth for image, voice, and skills
Most teams that try to add image generation to a Copilot workflow end up wiring two products and two auth flows. Gathos is one API key for image and TTS. Less ceremony.
03
Predictable pricing for an agent that loops
Copilot Agents are eager to generate. Per-image APIs combined with eager agents produce real bills. Gathos flat $18 with the 6-hour fair-use window means the cost surface is bounded by design.
04
Works in GitHub Actions too
The same skill files work as scripts in CI. Generate OG images on every PR, regenerate audio walkthroughs on every release, all from the same flat $18.

Frequently asked questions

Does GitHub Copilot support custom tools?+
Yes, via the Copilot Agents framework that went GA in 2026 and via MCP server integration. Both routes work for Gathos. The install script picks the right path based on your Copilot version.
Where does Copilot find the Gathos skills?+
Copilot reads skill metadata from your `~/.copilot/agents/` directory (or the project-scoped `.github/copilot-agents/`). The Gathos installer drops files there and Copilot picks them up on next reload.
Will this work in Visual Studio (full IDE) or only VSCode?+
Both. And in JetBrains. The Copilot Agents protocol is consistent across host editors.
Can I trigger Gathos from a GitHub Actions workflow?+
Yes. The same skills are CLI-callable. A common pattern is generating OG images on every PR via the Gathos CLI inside Actions.
Is this different from MCP?+
Slightly. Copilot Agents and MCP are related but not identical. Copilot supports both. Gathos works through either.

Using a different agent?

ChatGPT Custom GPTs

Image and voice generation, callable from a custom ChatGPT GPT.

Custom ChatGPT GPTs support Actions, which are HTTPS-callable tools the GPT can invoke during a conversation. Gathos exposes a clean OpenAPI schema so wiring it as an Action takes about ten minutes.

Continue

Image and voice generation in Continue.dev sessions.

Continue is the open-source alternative to Cursor, focused on developer control and self-hosting. It supports custom slash commands and tools through a clean config. Gathos plugs in as a callable tool so the agent can generate assets from the same editor session.

Aider

Image and voice generation, called from inside Aider sessions.

Aider is a terminal-first pair programmer that has stayed lean and fast. It does not ship with image generation or TTS, and the popular pattern is to bolt those on as external commands. Gathos slots in as a Bash-callable tool so an Aider session can generate assets without leaving the terminal.

Claude Code

Image generation and voice cloning for Claude Code.

Claude Code is the fastest-growing agent for power users. Gathos is the unified image + TTS API that plugs into Claude Code with a single install command. This page shows the install, a sample session, and the pre-built skills most teams install first.

Gemini CLI

Image and voice generation, native to Gemini CLI.

Gemini CLI's Skills spec went GA in early 2026 · same single-file markdown convention Anthropic and Codeium adopted. Gathos installs as a Gemini CLI skill so the agent can generate images and voiceover from any terminal session.

Cursor

Image generation and voice cloning in Cursor.

Cursor is where millions of developers write code every day. Gathos plugs into Cursor as a set of agent-callable skills · you describe what you want in a chat message, Cursor runs the API, and the output lands in your project folder. Flat $18/month.

Windsurf

Image generation and voice cloning, native to Windsurf.

Windsurf shipped Cascade Skills in Wave 13 (January 2026), and the spec is the same single-file markdown convention Anthropic and Cursor adopted. Gathos plugs in as a Cascade Skill so the agent can generate thumbnails, product shots, voiceover, and dubbed videos without you leaving the editor.
