Best for
  • Developers and platform engineering teams using Terraform
  • Teams maintaining multi-cloud architecture documentation
  • Users who want local processing of infrastructure code
  • Developers using fast-moving frameworks/libraries worried about the AI suggesting stale code
  • Scenarios wanting zero-config documentation lookup
Not for
  • Projects that do not use Terraform
  • Workloads requiring complete Azure or GCP resource coverage
  • Users seeking server-side cloud discovery or remote infrastructure management
  • Looking up internal/private codebase documentation (Context7 targets publicly published open-source libraries)
  • Cases needing very high coverage of obscure, niche libraries (coverage depends on what Context7's platform has indexed)
Required permissions
  • It needs to read local Terraform projects, variable files, and optionally plan JSON and graph DOT files
  • Normal operation requires local Terraform, Graphviz, and Git installations
  • AWS credentials are needed when using AWS Bedrock for AI annotations
  • Usable without an API key (subject to a free-tier rate limit); CONTEXT7_API_KEY is an optional credential for higher quota
  • Read-only documentation lookup — no code execution or local filesystem access involved
Risks and side effects
  • Azure and GCP currently have partial support limited to core services, so diagrams may be incomplete
  • When Bedrock or another REST API annotation backend is enabled, metadata and a summary graph are sent to the configured model service; the README states that .tf source files are not sent
  • Generated diagrams depend on the accuracy of the Terraform, plan, or graph inputs and do not replace infrastructure validation
  • The free tier has limited quota — high-frequency use may hit rate limits
  • Documentation content comes from Context7's platform index, so its accuracy and freshness depend on that platform's crawl cadence
