no key required for basic public doc lookups; set CONTEXT7_API_KEY (or pass `--api-key`) for higher rate limits and private-repo docs.

No credentials required.

Variable	Required	Auth mode	Description
CONTEXT7_API_KEY	no	api-key	Optional Context7 API key for higher rate limits and private-repo docs. Anonymous use works for basic public doc lookups. Equivalent to the `--api-key` CLI flag (the flag takes precedence when both are set); pass via env, never inline in args (doctrine #6).
CONTEXT7_API_URL	no	any	Optional Context7 API endpoint override; defaults to https://context7.com/api. Set when routing through a self-hosted or proxied Context7 backend.
HTTPS_PROXY	no	any	Optional standard HTTP(S) egress proxy (also reads `https_proxy`). Set when the host requires an outbound proxy to reach the Context7 API.
NODE_EXTRA_CA_CERTS	no	any	Optional path to an extra CA-certificate bundle for TLS — for corporate proxies or certificate-inspecting gateways that re-sign the Context7 endpoint.

context7.resolve-library-id
Resolve a package/framework name (`libraryName`) to a Context7-compatible library id.
context7.get-library-docs
Fetch current documentation for a resolved library id (`context7CompatibleLibraryID`), optionally scoped by `topic` and paginated via `page`.

FAI cookbook recipes that attach context7.

No destructive tools — audited read-only

Destructive-action audit (X2.18): no destructive tools — documentation retrieval is read-only.

Read-only documentation retrieval; cannot modify any resource.
Anonymous use is rate-limited — set CONTEXT7_API_KEY for production workloads and private-repo docs.
Network egress to the Context7 API is required; behind a proxy set HTTPS_PROXY (and NODE_EXTRA_CA_CERTS for a custom CA bundle).
