Infisical Mcp Server

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_AUTH_METHOD: The authentication method to use. Supported values are universal-auth and access-token. Defaults to universal-auth.
• INFISICAL_UNIVERSAL_AUTH_CLIENT_ID: The Machine Identity universal auth client ID. Required when INFISICAL_AUTH_METHOD is universal-auth.
• INFISICAL_UNIVERSAL_AUTH_CLIENT_SECRET: The Machine Identity universal auth client secret. Required when INFISICAL_AUTH_METHOD is universal-auth.
• INFISICAL_TOKEN: An access token for authentication. This can be both a personal access token or a machine identity access token. Required when INFISICAL_AUTH_METHOD is access-token.
• 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 Infisical MCP server using npx, use the following command:

npx -y @infisical/mcp
