| Client coverage | ||
| Client coverage details | Not documented | Claude Code✓ Streamable HTTP Claude Desktop✓ Streamable HTTP Codex✓ Streamable HTTP VS Code✓ Streamable HTTP Cursor✓ Streamable HTTP OpenCode✓ Streamable HTTP |
| Client coverage note | Local stdio runs on your computer. Streamable HTTP connects to a remotely hosted MCP server. | |
| Access and data | ||
| Authentication | Hosted service uses OAuth/dynamic client registration; local server can use a scoped Klaviyo private API key. | Hosted mode supports OAuth or Authorization Bearer APIFY_TOKEN; local stdio uses APIFY_TOKEN. Discovery tools can be unauthenticated, and agentic payment tokens are additional alternatives. |
| Cost | Klaviyo plan/API and model/provider costs apply. | Actor and platform usage is chargeable according to Actor pricing; even free Actors incur platform usage. x402, Skyfire, and AGI payment paths are documented; no fixed MCP fee is stated. |
| Permissions | Permissions follow OAuth/API scopes. Hosted read-only mode disables write tools; UGC-related tools can also be disabled. | Dynamically exposes Apify Actors, including web, social, maps, and e-commerce scrapers, plus run, dataset, key-value-store, and documentation tools. call-actor executes external Actors. |
| Data handling | Marketing/customer/account data and potentially user-generated content can be exposed to the AI client/provider. Klaviyo explicitly provides a control to disable UGC tools. | Requests and Actor inputs are sent to Apify; run results can be stored in Apify datasets and key-value stores. Telemetry is enabled by default and stdio uses Sentry; detailed retention is not documented. |
| Limitations | ||
| Tradeoffs |
|
|
| Risk context | Sensitive customer/marketing data, mutating campaign operations and prompt-injection risk from user-generated content require explicit controls. | Actor execution can scrape external sites, process personal or regulated data, incur spend, and return untrusted content. Restrict tools, use scoped tokens, review Actor pricing and terms, and control telemetry and storage. |
