API docs from ChatGPT, Claude and Gemini

Add the Skmtc MCP server to your assistant, then attach an OpenAPI schema or give its URL in a chat. The assistant calls the create_api_docs tool, which publishes the schema to your Skmtc account and gives you the link to the docs. This page tells you how to add the server to ChatGPT, Claude and Gemini.

Each assistant uses the same address:

https://mcp.skmtc.dev/mcp/publish

The first time the assistant uses the server, you sign in with GitHub. For the tools and the other endpoint, see Connect your agent over MCP.

Private and public docsCopy Anchor Link

The docs are private unless you ask for public docs. Only you can read private docs. To get public docs, say so in your message, for example "Make public API docs from this schema". For private docs, the reply also gives the settings page of the API. To make the docs public later, change the visibility on that page.

When Skmtc is in the ChatGPT plugin directory, add it from there. Until then, add it as a custom MCP server:

1. Go to chatgpt.com/plugins.
2. Select +, then Add custom MCP server.
3. Enter the name Skmtc and a description.
4. Under Connection, enter the URL https://mcp.skmtc.dev/mcp/publish.
5. Set the authentication to OAuth. Read the risk warning, then select I understand and want to continue.
6. Select Create as a plugin, and check the tools that ChatGPT shows.

Install the plugin and start a new chat. Type @ and select Skmtc. Then attach the schema file or give its URL, and ask for API docs. Your account and workspace policies control whether you can add a custom MCP server. See Connect from ChatGPT.

Add Skmtc as a custom connector. A free plan can add one custom connector.

1. Go to Customize > Connectors.
2. Select + Add, then Add custom connector.
3. Enter the name Skmtc and the URL https://mcp.skmtc.dev/mcp/publish, then select Continue.
4. Check the authentication settings, then select Continue.
5. Under Authentication, select Sign in now. Under OAuth client, select Register automatically.
6. Select Add, then sign in with GitHub.

On a Team or Enterprise plan, an owner adds the connector for the organization. The owner goes to Organization settings > Connectors, selects Add, then Custom > Web, and does steps 3 to 6. Each member then goes to Customize > Connectors, finds Skmtc and selects Connect.

In a chat, select +, then Connectors, and turn on Skmtc. Then attach the schema file or give its URL, and ask for API docs. See Get started with custom connectors using remote MCP.

In Claude Code, add the server with this command:

claude mcp add --transport http skmtc https://mcp.skmtc.dev/mcp/publish

Then run /mcp, select skmtc and sign in. Give Claude Code the path or the URL of the schema, and ask for API docs.

3. Under Custom apps, select Add a custom app.
4. Enter the URL https://mcp.skmtc.dev/mcp/publish, then select Next.
5. Do the steps on the screen, and sign in with GitHub.

In a chat, type @ and select Skmtc. Then attach the schema file or give its URL, and ask for API docs. See Connect custom apps to Gemini.
