Cloudinfra

cloudinfra

AWS infrastructure-as-code guidance as MCP tools: Terraform Registry documentation and module lookups, a local policy scan for terraform plan files, and plain-language explanations of common AWS resource types. cloudinfra is a clean-room rebuild of the core surface of the aws-terraform MCP server, under a new name: fresh code and prose, no copied branding.

Tools (core subset, 10)

search_provider_docs, get_provider_doc_details, search_cc_provider_docs, list_provider_resources, search_modules, get_module_details, get_latest_provider_version, search_user_guide, run_policy_scan, explain_resource.

Not in this subset: Terraform/Tofu CLI execution (init/plan/apply), provider schema generation, pricing and cost estimation, LLM-assisted code or module generation, state manipulation, and any write or deploy operation.

How it works

The docs and module tools are shaped GET requests against the public Terraform Registry API (https://registry.terraform.io/v1, base overridable with TERRAFORM_REGISTRY_URL) through an injectable fetch function. No credentials are needed for any tool.

run_policy_scan is fully local and deterministic. Give it a terraform plan JSON (the output of terraform show -json) and it walks planned_values (including child modules; resource_changes is a fallback) checking four rule families:

• public-s3 — S3 buckets with a public ACL
• unencrypted-storage — RDS/EBS without encryption, S3 buckets with no server-side encryption configuration
• wildcard-iam — IAM policies granting wildcard actions or resources
• open-security-group — ingress open to 0.0.0.0/0 or ::/0

An external scanner can be injected through the library API as a scan executor; none is bundled — the local checker is the default and the only implemented scanner.

explain_resource answers from a small curated catalogue of common AWS resource types written for this rebuild, and says so plainly for types outside the catalogue.

CLI

npx @reneturcios/cloudinfra explain_resource '{"resource_type":"aws_s3_bucket"}'npx @reneturcios/cloudinfra run_policy_scan '{"plan":{...}}'npx @reneturcios/cloudinfra mcp        # stdio MCP server

Each tool name is a subcommand taking one JSON object argument.
