No MCP rate limits or SLA were found, and status.amplitude.com records a critical outage of the UI, MCP and REST APIs on 13 July 2026.\n\n**GrowthBook.** GrowthBook Cloud's MCP server has four tools with read and write annotations, OAuth with dynamic client registration, and a 414-operation OpenAPI spec behind it. The free plan needs no card. The API tools pass paths and JSON bodies through without validation, every key is limited to 60 requests a minute, and audit logs are Enterprise only.\n\n## Before you call either\n\n### Amplitude\n\n1. Connect to https://mcp.amplitude.com/mcp, or https://mcp.eu.amplitude.com/mcp for EU projects. The client must support streaming HTTP and OAuth, since API keys aren't accepted\n2. Append `?discovery=progressive` to load tool schemas on demand, then call `get_amplitude_context` first to pick the project and read its AI context\n3. Ask an admin for a role with only Use MCP (read) on the projects you need. Tools stay listed and fail at call time when the role lacks the action\n4. Send events through the HTTP V2 API with an `insert_id` on each one. On 429, pause that user or device for 30 seconds before retrying\n5. Budget Dashboard REST queries by cost (days times conditions times chart cost), within 108,000 an hour and 5 concurrent requests per project\n\n### GrowthBook\n\n1. Connect to https://mcp.growthbook.io/mcp and complete OAuth in a browser. Use https://mcp.growthbook.io/mcp/api for the two API tools alone\n2. Call `growthbook_list_skills` and `growthbook_read_skill` before writing. The API tools don't validate payloads, so use the paths the skill names\n3. Stay under 60 requests a minute per key. On 429 wait for the `RateLimit-Reset` seconds before retrying\n4. List calls return 10 items by default. Pass `limit` up to 100 and `offset` to page\n5. A 422 is a soft warning. Resubmit with `?ignoreWarnings=true` only after reading the message\n\n## Questions\n\n### Which is better for AI agents, Amplitude or GrowthBook?\n\nGrowthBook scores 70.1 (BB) on agent readiness against Amplitude's 66.2 (B), and leads in 5 of 7 scored categories. Amplitude leads on security \u0026 auth.\n\n### Do Amplitude and GrowthBook need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Amplitude and GrowthBook without installing anything?\n\nYes. Amplitude has a hosted endpoint at https://mcp.amplitude.com/mcp and GrowthBook at https://mcp.growthbook.io/mcp.\n\n### Are Amplitude and GrowthBook open source?\n\nNo open-source release is listed for Amplitude. GrowthBook is open source (MIT for the core and for the MCP server. Three enterprise directories in the main repository are under GrowthBook's enterprise licence.
