HUBSPOT_TOOL_MODE'discovery' (default) exposes 3 meta-tools that search, inspect and call all 1,076 endpoints; 'all' exposes the ~690 endpoint tools directly.
HUBSPOT_READ_ONLYSet to 'true' to expose only read-only tools.
HUBSPOT_CAPABILITY_CHECKRead the token's scopes and probe paid-tier or beta API groups at startup (read-only, up to about 30 API calls). Set to 'false' to skip.
