AI agents call providerDetails to retrieve information from Terraform without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
version | string | — | Provider version (defaults to latest) |
provider | string | — | Provider name (e.g. 'aws') |
namespace | string | — | Provider namespace (e.g. 'hashicorp') |
Parameters from the server's own tool schema.
This tool queries and returns metadata about Terraform providers from the registry. It performs data retrieval only, analogous to a documentation lookup or API GET request. There are no side effects, code execution, data modification, or destructive operations. The sibling tools (moduleDetails, resourceArgumentDetails, policyDetails) follow the same read-only pattern, reinforcing this classification.
From the tool's definition Tool retrieves 'detailed information about a Terraform provider by name and optionally version' - a lookup/query operation with no modification or execution capability.
Attacks that exploit this kind of access
Get detailed information about a Terraform provider by name and optionally version. It is categorised as a Read tool in the Terraform MCP Server, which means it retrieves data without modifying state.
providerDetails accepts 3 parameters: version, provider, namespace. The full parameter table on this page comes from the server's own tool schema.
Register the Terraform MCP server in PolicyLayer and add a rule for providerDetails: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Terraform. Nothing to install.
providerDetails is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the providerDetails rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for providerDetails. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
providerDetails is provided by the Terraform MCP server (terraform-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
