Client coverage
Client coverage details	Not documented	Claude Code✓ Local stdio Claude Desktop✓ Local stdio Codex✓ Local stdio VS Code✓ Local stdio Cursor✓ Local stdio OpenCode✓ Local stdio
Client coverage note	Local stdio runs on your computer. Streamable HTTP connects to a remotely hosted MCP server.
Access and data
Authentication	ZoomInfo's hosted MCP uses OAuth through the user's ZoomInfo account; no API keys are stored in the public plugin repository.	The server itself does not require a service account for local stdio use, but websites opened in the controlled browser may use cookies or other authenticated browser state.
Cost	A ZoomInfo account with appropriate API access and product entitlements is required. The reviewed public MCP material does not state a separate MCP price.	The first-party open-source package lists no MCP server usage fee. Normal internet, hosted-client, proxy, or third-party website costs can still apply.
Permissions	Use requires a ZoomInfo account with the appropriate API access and product entitlements. The MCP acts within the access provided by that account.	The exposed tools can navigate pages, interact with elements, enter text, upload files, inspect network activity, and optionally use additional browser capabilities.
Data handling	Not documented in the reviewed sources. The reviewed MCP repository does not provide an MCP-specific retention/training statement. It exposes ZoomInfo company/contact/intent and related go-to-market data to the authenticated client.	Page text, accessibility snapshots, console output, network details, uploaded paths, and browser state may be returned to the connected MCP client. Isolated mode keeps the temporary profile in memory; persistent mode stores browser state on disk.
Limitations
Tradeoffs	MCP hosted tool inventory needs account verification; prefer client-native OAuth	A persistent profile is convenient but can retain cookies and authenticated state between sessions. Origin allow/block options reduce accidental access but the publisher explicitly says they are not a security boundary.
Risk context	The principal risk is disclosure or misuse of licensed business/contact data and intent/enrichment information. Account entitlements and contractual restrictions remain relevant.	Playwright MCP is not a security boundary. Secret replacement or masking is a convenience feature, not a security boundary. Prefer an isolated browser profile, non-sensitive test accounts, narrow destinations, minimal optional permissions, and client-side approval controls.
