The status page shows 31 incidents in 90 days, four on analytics queries, and three security incidents were disclosed in the last year.\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### PostHog\n\n1. Add `?readonly=true` or the `x-posthog-read-only` header to the MCP URL unless the task needs writes\n2. Pin the session with `x-posthog-project-id`, which also removes the `switch-project` and `switch-organization` tools\n3. In CLI mode run `info \u003ctool\u003e` once before `call`, and send one `exec` command per request\n4. On a 429 with code `api_queries_budget_exceeded`, wait for `Retry-After` and read `X-PostHog-Query-Budget-Remaining-Bytes`\n5. Page SQL results by keyset on `timestamp`. `OFFSET` returns 400 for personal API keys, and results cap at 50,000 rows\n\n## Questions\n\n### Which is better for AI agents, Amplitude or PostHog?\n\nPostHog scores 68.4 (B) on agent readiness against Amplitude's 66.2 (B), and leads in every scored category.\n\n### Do Amplitude and PostHog need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Amplitude and PostHog without installing anything?\n\nYes. Amplitude has a hosted endpoint at https://mcp.amplitude.com/mcp and PostHog at https://us.posthog.com.\n\n### Are Amplitude and PostHog open source?\n\nNo open-source release is listed for Amplitude. PostHog is open source (MIT for the repository outside the `ee` directory, which has its own licence.
