Limitations and notes
  • Enrichment consumes Apollo credits. Master keys are workspace-level credentials. Apollo prohibits model training on Apollo MCP data.
Original sources
  • official documentation

    Official Apollo MCP docs document endpoint, OAuth or X-Api-Key auth, contact/company search and enrichment, sequences and task/email workflows; they direct clients to discover tools dynamically and do not publish a stable roster.
