Implementation Reference

• src/tools/terraform/plan.ts:6-19 (handler)

  The implementation of the `terraform_plan` tool logic, which executes `terraform plan` using `child_process`.

  export async function terraformPlan(args: Record<string, unknown>): Promise<string> {
    const directory = args.directory as string;
    if (!directory) throw new Error("Terraform directory is required");
  
    try {
      const { stdout, stderr } = await execFileAsync("terraform", ["plan", "-no-color", "-input=false"], {
        cwd: directory,
        timeout: 120000,
      });
      return `Terraform plan for '${directory}':\n\n${stdout}${stderr ? `\nWarnings:\n${stderr}` : ""}`;
    } catch (error: any) {
      throw new Error(`Terraform plan failed: ${error.stderr || error.message}`);
    }
  }

• src/tools/terraform/index.ts:8-18 (schema)

  Registration of the `terraform_plan` tool, including its name, description, and input schema.

  {
    name: "terraform_plan",
    description: "Run terraform plan to preview infrastructure changes (read-only, safe)",
    inputSchema: {
      type: "object" as const,
      properties: {
        directory: { type: "string", description: "Directory containing Terraform files" },
      },
      required: ["directory"],
    },
  },

• src/tools/terraform/index.ts:68-81 (handler)

  The handler function that routes calls to `terraform_plan` to the appropriate implementation.

  export async function handleTerraformTool(
    name: string,
    args: Record<string, unknown> | undefined
  ): Promise<string> {
    const a = args || {};
    switch (name) {
      case "terraform_plan": return terraformPlan(a);
      case "terraform_state_list": return terraformStateList(a);
      case "terraform_state_show": return terraformStateShow(a);
      case "terraform_output": return terraformOutput(a);
      case "terraform_validate": return terraformValidate(a);
      default: throw new Error(`Unknown Terraform tool: ${name}`);
    }
  }
