Your TripAdvisor Terra API key (tripadvisor.com/developers). Needed by the Terra tools; the ta_web_* tools work without it. Secret.
TRIPADVISOR_CACHE_TTL
No
Seconds to cache search responses (default: 300; `0` disables).
TRIPADVISOR_STATIC_CACHE_TTL
No
Seconds to cache details/photos/reviews (default: 3600; `0` disables).
TRIPADVISOR_REQUEST_TIMEOUT_MS
No
Per-request timeout for the optional browser bridge (default: 30000).
TRIPADVISOR_DEBUG_LOG
No
Set to `1` to log browser-bridge requests to stderr.
TRIPADVISOR_WS_PORT
No
Bridge port override (default: FETCHPROXY_WS_PORT, else 37149). Tests only.
FETCHPROXY_WS_PORT
No
Localhost concentrator port (default 37149). On one machine every MCP shares the concentrator, so move it for ALL of them or not at all.
FETCHPROXY_WS_HOST
No
Bind interface (default 127.0.0.1; a literal IP only, anything else is ignored). Keep on loopback — it exists for ONE topology: a hosted child in its own network namespace.
FETCHPROXY_IDENTITY_DIR
No
Where to store the long-term identity keypair (default ~/.fetchproxy/identity/; an absolute path only, anything else is ignored). Exists for a host that runs a separate child per caller, so they can share one identity.
