Connect ChatGPT

ChatGPT can use Agent Finder through a Skill plus a way to make the call — either a remote MCP connector (Developer mode) or a custom Action over the REST POST /search. The Skill supplies the behavior; the connector or Action makes the request.

Option A — Skill

ChatGPT Skills are reusable instruction sets, available on Business, Enterprise, Edu, and Team plans. Unlike Claude and Copilot, a ChatGPT Skill lives in your workspace, not in a file — you add it through the UI.

Install. In your ChatGPT workspace, use Add skill to open the Skills editor, then create the skill from the connectors repo (skills/chatgpt/):

  • Name: agentfinder
  • Instructions: paste the body of that file (show a menu of named Agent Finders, remember the choice, present the ranked results, and never auto-install).

A Skill on its own can't make network calls, so pair it with Option B (MCP connector) or a custom Action whose OpenAPI calls POST https://agentfinder.github.com/api/v1/search.

How to invoke it

ChatGPT can use the skill automatically when it's relevant, or you can invoke it explicitly by @-mentioning it:

@agentfinder find me a tool for converting CSVs to charts

Either way it shows a menu of Agent Finders the first time (and remembers your pick), runs the query via the connector/Action, and presents the matches for you to pick from.

Option B — Remote MCP connector (Developer mode)

ChatGPT supports remote MCP servers (HTTPS, Streamable HTTP / SSE) through Developer mode (Plus, Pro, Business, Enterprise, Education).

  1. Settings → Apps → Advanced settings → Developer mode (enable it).
  2. Create app next to Advanced settings.
  3. Name it Agent Finder and paste the remote MCP URL — https://agentfinder.github.com/api/v1/mcp (or your own discovery service).
  4. Choose authentication — No authentication for an open Agent Finder, or OAuth if it requires sign-in.
  5. Save — the search tool is now available in chat.

How to invoke it

Ask ChatGPT to find a capability for your task; it calls the Agent Finder search tool and lists the matches. Pair it with the Skill (Option A) so it asks first and never auto-installs.

Endpoint

Examples use GitHub's Agent Finder (https://agentfinder.github.com/api/v1); Hugging Face Discover (https://huggingface-hf-discover.hf.space/search) works the same way. Point at either — or any compliant ARD discovery service — see Endpoints.
