## Which one, for what

### Amplitude (B)

Good for: A team already on Amplitude that wants an agent to query charts, funnels, retention and experiment results, edit dashboards and manage the tracking plan under its own permissions.

Ahead on:
- Reliability, 60 against 28
- Agent ergonomics, 72 against 66
- Security & auth, 74 against 63
- Payments & pricing, 30 against 17
- Transparency & trust, 78 against 70

Also in its favour:
- Free to start without a card

Watch for: No rate limit for the MCP server or the Developer API was found in the reviewed documentation

### Countly (C)

Good for: An agent whose owner runs Countly on its own infrastructure or a dedicated Flex server and wants analytics, crash and remote-config data through MCP with per-category permissions.

Also in its favour:
- Runs on your own machine
- Open source

Watch for: No public status page or incident history was found for Flex servers or for mcp.count.ly

## 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
