How to Set Up and Use Infisical
Infisical MCP Server is an official integration that connects AI assistants to Infisical's secrets management platform, enabling agents to create, read, update, delete, and list secrets through natural language function calls. It supports both universal machine identity authentication and personal access tokens, and works with both Infisical Cloud and self-hosted instances. Security and DevOps teams can use it to let AI agents manage environment secrets, create projects, set up environments, and invite team members without leaving their AI workflow.
Prerequisites
- Node.js and npx installed
- Infisical account (cloud at app.infisical.com or self-hosted instance)
- Machine Identity with Client ID and Client Secret (for universal-auth), or a personal/machine access token
- An MCP client such as Claude Desktop
Create a Machine Identity in Infisical
Log in to your Infisical dashboard, navigate to Organization Settings → Machine Identities, and create a new identity. Copy the Client ID and Client Secret that are generated.
Grant the identity access to your projects
In each Infisical project where you want the MCP server to manage secrets, add the machine identity as a member with the appropriate role (e.g., Developer or Admin).
Test the server locally
Run the server directly with npx to verify it starts without errors before configuring Claude Desktop.
INFISICAL_UNIVERSAL_AUTH_CLIENT_ID=your_client_id \
INFISICAL_UNIVERSAL_AUTH_CLIENT_SECRET=your_client_secret \
npx -y @infisical/mcpAdd the server to Claude Desktop
Edit your claude_desktop_config.json to register the Infisical MCP server with your machine identity credentials.

}
}Restart Claude Desktop
Fully quit and relaunch Claude Desktop so it registers the Infisical MCP server.

Example prompts for managing secrets and projects in Infisical.
- "List all secrets in the production environment of my backend project"
- "Create a new secret DATABASE_URL in the staging environment"
- "Update the API_KEY secret in the development environment to a new value"
- "Create a new Infisical project called mobile-app"
- "Invite [email protected] to the backend project with developer access"Troubleshooting Infisical
Authentication fails with 'Unauthorized' error
Verify INFISICAL_UNIVERSAL_AUTH_CLIENT_ID and INFISICAL_UNIVERSAL_AUTH_CLIENT_SECRET are correct. Confirm the machine identity is active and not expired in your Infisical dashboard.
Secrets are not visible for a specific project
The machine identity must be explicitly added as a member of each project you want to access. Go to the project's Access Control settings and add the identity with the appropriate role.
Connection error for self-hosted Infisical instance
Set INFISICAL_HOST_URL to your self-hosted instance URL (e.g., https://infisical.yourcompany.com). Without this, the server defaults to app.infisical.com.
