Infisical Model Context Protocol

The Infisical Model Context Protocol server allows you to integrate with Infisical APIs through function calling. This protocol supports various tools to interact with Infisical.

Setup

Environment variables

In order to use the MCP server, you must first set the environment variables required for authentication.

• INFISICAL_UNIVERSAL_AUTH_CLIENT_ID: The Machine Identity universal auth client ID that will be used for authentication
• INFISICAL_UNIVERSAL_AUTH_CLIENT_SECRET: The Machine Identity universal auth client secret that will be used for authentication.
• INFISICAL_HOST_URL: Optionally set a custom host URL. This is useful if you're self-hosting Infisical or you're on dedicated infrastructure. Defaults to https://app.infisical.com

To run the Stripe MCP server using npx, use the following command:

npx -y @infisical/mcp
