Verdicts

Amplitude

The remote MCP server covers queries, funnels, retention, experiments and flags under OAuth with PKCE, read and write scopes and per-project role actions, and the Free plan needs no card. 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.

Countly

Countly suits an agent working against a server its owner already runs. The official MCP server filters its 209 tools by edition, plugin and permission and has per-category read-only settings. No status page, OpenAPI document or published API rate limit was found, and the Flex trial needs a credit card.

Before you call either

Amplitude

  1. 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
  2. Append ?discovery=progressive to load tool schemas on demand, then call get_amplitude_context first to pick the project and read its AI context
  3. 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
  4. 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
  5. Budget Dashboard REST queries by cost (days times conditions times chart cost), within 108,000 an hour and 5 concurrent requests per project

Countly

  1. Create a dedicated token in the Token Manager, limited to the apps and endpoints the task needs, and send it in the countly-token header, not the URL
  2. Set COUNTLY_TOOLS_ALL=R unless the task needs writes. The token's own permissions still apply and the stricter of the two wins
  3. Call apps_list first. Most tools need app_id or an exact app_name
  4. Check get_version for the detected edition before planning funnel, retention or cohort queries, which need Enterprise plugins
  5. Set ENABLE_ANALYTICS=false to stop usage reports to stats.count.ly, and prefer the stdio server to mcp.count.ly so the server URL and token stay local
