Terraform Provider for Frontegg AgentLink

A Terraform provider for managing Frontegg AgentLink resources. AgentLink enables you to build and deploy secure AI agents with enterprise-grade access control, data masking, and Model Context Protocol (MCP) integration.

What is Frontegg AgentLink?

Frontegg AgentLink is a platform for building secure AI agents that can interact with your APIs and services. It provides:

Model Context Protocol (MCP) Support: Standard protocol for AI model interactions with tools and APIs
Enterprise Security: Role-based access control (RBAC), data masking, and conditional policies
Multi-Source Integration: Connect REST APIs, GraphQL endpoints, and custom integrations
Tool Management: Import tools from OpenAPI/GraphQL schemas with automatic discovery

This Terraform provider allows you to manage all AgentLink resources as Infrastructure as Code (IaC), enabling version control, reproducibility, and automation of your AI agent infrastructure.

Requirements

Terraform >= 1.0
Go >= 1.24 (only for building from source)
A Frontegg account with AgentLink access

Installation

From Terraform Registry (Recommended)

Add the provider to your Terraform configuration:

terraform {
  required_providers {
    agentlink = {
      source  = "frontegg/agentlink"
      version = "~> 0.1"
    }
  }
}

Then run:

terraform init

From Source

Clone the repository and build:

git clone https://github.com/frontegg/terraform-provider-agentlink.git
cd terraform-provider-agentlink
make install

This installs the provider to ~/.terraform.d/plugins/.

Quick Start

Set up authentication using environment variables:

export FRONTEGG_CLIENT_ID="your-client-id"
export FRONTEGG_SECRET="your-secret"

Create a basic configuration (main.tf):

terraform {
  required_providers {
    agentlink = {
      source = "frontegg/agentlink"
    }
  }
}

provider "agentlink" {}

# Create an AI agent application
resource "agentlink_application" "my_agent" {
  name      = "My AI Agent"
  app_url   = "https://agent.example.com"
  login_url = "https://agent.example.com/login"
  type      = "agent"
  allow_dcr = true
}

# Configure MCP settings
resource "agentlink_mcp_configuration" "config" {
  application_id = agentlink_application.my_agent.id
  base_url       = "https://api.example.com"
}

Apply the configuration:

terraform init
terraform plan
terraform apply

Authentication

The provider requires Frontegg API credentials. Obtain these from the Frontegg Portal under Settings > API Keys.

Option 1: Environment Variables (Recommended)

export FRONTEGG_CLIENT_ID="your-client-id"
export FRONTEGG_SECRET="your-secret"
export FRONTEGG_REGION="eu"  # Optional, defaults to "eu"

Option 2: Provider Configuration

provider "agentlink" {
  client_id = "your-client-id"
  secret    = "your-secret"
  region    = "eu"
}

Option 3: Using Variables (for CI/CD)

variable "frontegg_client_id" {
  type      = string
  sensitive = true
}

variable "frontegg_secret" {
  type      = string
  sensitive = true
}

provider "agentlink" {
  client_id = var.frontegg_client_id
  secret    = var.frontegg_secret
}

Security Best Practices

1. Use Environment Variables for Credentials

Never commit credentials to version control:

export FRONTEGG_CLIENT_ID="your-client-id"
export FRONTEGG_SECRET="your-secret"

2. Enable Data Masking

Always enable masking for sensitive data:

resource "agentlink_masking_policy" "default" {
  name              = "Default PII Masking"
  enabled           = true
  internal_tool_ids = []

  policy_configuration {
    email_address = true
    phone_number  = true
    credit_card   = true
    us_ssn        = true
  }
}

3. Implement Least Privilege with RBAC

Restrict tool access by roles:

resource "agentlink_rbac_policy" "least_privilege" {
  name              = "Principle of Least Privilege"
  enabled           = true
  type              = "RBAC_ROLES"
  keys              = ["specific-role"]
  internal_tool_ids = ["specific-tool-id"]
}

4. Require Approval for Destructive Operations

resource "agentlink_conditional_policy" "destructive_ops" {
  name              = "Approval for Destructive Operations"
  enabled           = true
  internal_tool_ids = []

  targeting {
    if {
      condition {
        attribute = "tool.method"
        op        = "in_list"
        negate    = false
        value     = { list = "DELETE,PUT,PATCH" }
      }
    }
    then {
      result = "APPROVAL_REQUIRED"
    }
  }
}

5. Use State Encryption

When using remote state, ensure it's encrypted:

terraform {
  backend "s3" {
    bucket         = "terraform-state"
    key            = "agentlink/terraform.tfstate"
    region         = "us-east-1"
    encrypt        = true
    dynamodb_table = "terraform-locks"
  }
}

Development

Building

make build

Installing Locally

make install

Running Tests

make test        # Unit tests
make testacc     # Acceptance tests (requires credentials)

Code Quality

make fmt         # Format code
make vet         # Run go vet
make tidy        # Tidy dependencies

Testing with Terraform

Copy the example tfvars file:

cp examples/provider/terraform.tfvars.example examples/provider/terraform.tfvars

Edit terraform.tfvars with your credentials

Troubleshooting

Authentication Errors

Error: 401 Unauthorized

Verify your client_id and secret are correct
Check that credentials have appropriate permissions
Ensure you're using the correct region

Resource Not Found
