## What it does

The server exposes Amplitude’s analytics surface as tools an agent can compose. Event queries are the base: count and segment events over a time range, filtered by user or event properties. On top of that sit the analyses Amplitude is known for — funnels with conversion and drop-off per step, retention curves by cohort, and segmentation that compares one user group against another. A model can also inspect the event taxonomy, which is the unglamorous but decisive part: knowing which events actually exist, and what properties they carry, is what separates a real answer from a confident guess about an event name that was never instrumented. Amplitude operates separate US and EU deployments and the endpoints are distinct, so EU customers connect to mcp.eu.amplitude.com and their data stays in the region.

## Tools exposed

- event segmentation — count and break down events by property over time
- funnel analysis — conversion and drop-off across an ordered event sequence
- retention — cohort retention curves for a chosen start and return event
- user segments — define and compare cohorts of users
- event taxonomy — list instrumented events and their properties

## Example queries you can run

- "Where do users drop off between signup and first project created?"
- "Compare week-four retention for users who came from paid versus organic."
- "Which events fired most often last month, and which have stopped firing entirely?"
- "Has activation improved since the onboarding change on the first of the month?"

## Details

- **Recommended model:** anthropic/claude-sonnet-4.5 — Funnel and retention definitions are easy to get subtly wrong — wrong start event, wrong window. Sonnet 4.5 states its assumptions, which is what makes the number checkable.
- **Transport:** http
- **Authentication:** Required — Amplitude API credentials via an authorization header. EU projects must use https://mcp.eu.amplitude.com/mcp instead of the US endpoint.
- **Hosted endpoint:** https://mcp.amplitude.com/mcp
- **Official source:** [Amplitude documentation](https://amplitude.com/docs)

## Connecting to Amplitude

### Connection examples

**US**

```
https://mcp.amplitude.com/mcp
```

**EU**

```
https://mcp.eu.amplitude.com/mcp
```

Required for EU-resident projects — the US endpoint cannot see EU data.

## Frequently asked questions

### What is the Amplitude MCP server?

Amplitude’s official hosted MCP server. It exposes event segmentation, funnels, retention, cohorts and the event taxonomy as MCP tools, so an AI assistant can answer product analytics questions directly against your data.

### Is there an EU endpoint?

Yes. EU-resident projects use mcp.eu.amplitude.com rather than mcp.amplitude.com. They are separate deployments — pointing an EU project at the US endpoint will not find your data.

### Can it see events that were never instrumented?

No, and this is the most common source of confusion. The server can only analyse what your SDK actually sends. Ask it to list the event taxonomy first — the answer to "why is this funnel empty" is usually a missing event, not a broken query.

### How does it compare with the PostHog MCP server?

Amplitude leans on named analyses — funnel, retention, segmentation — as distinct tools. PostHog leans on HogQL, a SQL dialect, so it is more flexible but demands more query correctness. Amplitude is easier to get a right answer from; PostHog can answer stranger questions.

### Should an agent be allowed to create cohorts?

It is lower risk than most write operations, since a cohort is an analysis artefact rather than production config. The thing to watch is clutter — an agent that creates a cohort per question leaves a workspace nobody can navigate.
