No OpenAPI document, idempotency keys, published price or SLA were found, and MCP writes run without a confirmation step.\n\n**Klaviyo API + MCP.** The REST API has a public OpenAPI 3 description of 345 operations, scoped keys and OAuth, and dated revisions supported for two years. The hosted MCP server lists 274 tools with a read-only switch. No approval step before a campaign send was found in the reviewed documentation, and no SLA is published.\n\n## Before you call either\n\n### Braze\n\n1. Use the REST host for the customer's instance, such as https://rest.iad-01.braze.com or https://rest.fra-01.braze.eu. A key sent to the wrong instance returns 401\n2. Create a REST key with only the permissions the task needs. Scope and IP allowlist can't be edited later, so a change means a new key\n3. Call `get_workspaces` first on MCP. Every other tool needs the returned workspace id as `app_group_id`, and the wrong workspace is a documented failure\n4. Use REST for profiles, events and sends. The MCP server has no user-level tools and can't trigger a message to a named user\n5. Treat `\"message\": \"success\"` as queued, not delivered. Add a `group_id` to `/users/track` and poll `/users/track/status`, and don't resend a trigger call blindly\n\n### Klaviyo API + MCP\n\n1. Send `revision: 2026-07-15` on every call, and `Authorization: Klaviyo-API-Key \u003ckey\u003e` or an OAuth Bearer token\n2. Add `?read-only=true` or `?toolsets=profiles:read,campaigns:read` to https://mcp.klaviyo.com/mcp, with no trailing slash, to cut the 274 tools down\n3. Ask a person before `send_campaign` or POST /api/campaign-send-jobs. Nothing in the docs holds a send for approval\n4. On 429 wait for `Retry-After`, then back off with jitter. Creating a segment or a flow is limited to 1 a second, 15 a minute and 100 a day\n5. Set `unique_id` on events so a retry isn't recorded twice, and set `backfill` when loading history so flows don't fire\n6. Treat profile properties, event data and reviews as untrusted text, or set `disable-tools-with-user-generated-content=true`\n\n## Questions\n\n### Which is better for AI agents, Braze or Klaviyo API + MCP?\n\nKlaviyo API + MCP scores 71.7 (BB) on agent readiness against Braze's 61.2 (C), and leads in 5 of 7 scored categories.\n\n### Do Braze and Klaviyo API + MCP need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Braze and Klaviyo API + MCP without installing anything?\n\nYes.
