Best for
  • Teams using HCP Terraform or Terraform Enterprise
  • Developers integrating Terraform into IDEs like VS Code and Cursor
  • DevOps engineers automating IaC workflows
  • Developers using fast-moving frameworks/libraries worried about the AI suggesting stale code
  • Scenarios wanting zero-config documentation lookup
  • Developers auditing NPM dependencies within AI workflows
  • Teams performing supply chain security assessments
  • Users of Claude Desktop, Cursor, or VS Code
Not for
  • Not suitable for local-only Terraform use without HCP Terraform/Terraform Enterprise
  • Not for environments requiring complex custom instructions or high security without careful review
  • 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)
  • Projects outside the NPM ecosystem (e.g., pure Python/Go)
  • Environments without network access to deps.dev, OSV.dev, and the npm registry
  • Scenarios requiring maintenance by an official upstream vendor
Required permissions
  • Requires Terraform API token (TFE_TOKEN) to access HCP Terraform or Terraform Enterprise
  • Runs in a Docker container, requiring network access
  • If ENABLE_TF_OPERATIONS is enabled, can execute Terraform operations, requiring explicit approval
  • 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
  • Network access to the NPM registry and external services (deps.dev, OSV.dev, OpenSSF, npms.io, GitHub)
  • Read access to workspace lockfiles (pnpm-lock.yaml, package-lock., yarn.lock) for cache invalidation
Risks and side effects
  • Server may expose Terraform data to MCP client and LLM; avoid untrusted clients
  • Outputs are generated dynamically; review to align with security and cost policies
  • In streamable-http mode, TFE_ADDRESS cannot be set by clients to prevent redirect attacks
  • Shared secret (TF_MCP_SHARED_SECRET) should only be used over TLS
  • 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
  • Third-party READMEs and changelogs are untrusted external content; they are wrapped in tags with _meta flags but should still be handled cautiously
  • Depends on availability and accuracy of external services
  • Batch requests are capped at 25 packages to prevent registry enumeration; larger sets require batching
  • Third-party open source project, not officially maintained by NPM or Anthropic
