Docs MCP

What is MCP?

MCP (Model Context Protocol) is an open-source standard for connecting AI applications to external systems.

Using MCP, AI applications like ChatGPT, Cursor and Claude Code and others can connect to data sources, tools and workflows. It enables them to access key information and perform tasks.

What is PlainKey Docs MCP?

PlainKey Docs MCP is an MCP server that allows your AI assistant to read and understand PlainKey's documentation and articles. This way, it can assist you with setting up PlainKey for your web app.

It has access to all documentation pages and articles on plainkey.io.

ChatGPT Setup

Follow these steps to set up PlainKey Docs as a connector within ChatGPT:

1. Enable Developer mode:

• Go to "Settings" > "Connectors" > "Advanced settings" > "Developer mode"

2. Open ChatGPT settings
3. In the Connectors tab, create a new connector:

• Give it a name: PlainKey Docs MCP
• Description: Provides documentation for PlainKey, a passkey authentication service
• MCP server URL: https://docs-mcp.plainkey.io/mcp
• Authentication: None

4. Click Create

You can now ask ChatGPT to help you with setting up PlainKey for your project.

If ChatGPT says it doesn't have access, try clicking the + in the chat -> More -> PlainKey Docs to make ChatGPT aware you specifically want to use that connector.
