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**Statsig.** Statsig suits agents that manage feature gates and experiments and read their results. Its MCP server has 18 default tools, OAuth, read-only access by project and role, and a confirmation on updates. Errors carry only a status and a message, no idempotency keys were found, and the privacy notice is Amplitude's and doesn't name Statsig.\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### Statsig\n\n1. Connect to https://api.statsig.com/v3/mcp. The official MCP registry entry still lists the V1 URL, which has 93 tools\n2. Call `get_context` first to learn the project, your permissions and the review settings\n3. Read the resource before `gate_update`, `experiment_update` or `dynamic_config_update`. They replace the whole resource, so resend every field you want kept\n4. Use `discover_tools` for partial edits, and fetch a fresh `operationHandle` when one expires\n5. On a 429 slow down and back off with jitter. Rejected attempts count towards the quota of about 1,800 mutations per 15 minutes\n\n## Questions\n\n### Which is better for AI agents, Amplitude or Statsig?\n\nStatsig scores 72.3 (BB) on agent readiness against Amplitude's 66.2 (B), and leads in 3 of 7 scored categories.\n\n### Do Amplitude and Statsig need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Amplitude and Statsig without installing anything?\n\nYes. Amplitude has a hosted endpoint at https://mcp.amplitude.com/mcp and Statsig at https://api.statsig.com/v3/mcp.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/amplitude-vs-statsig.json, and with the fewest tokens: https://www.anchorterminal.com/compare/amplitude-vs-statsig.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"amplitude\", \"b\": \"statsig\"}`.
