Amplitude MCP Server

Amplitude MCP Server

A Model Context Protocol (MCP) server for Amplitude Analytics API, providing tools and resources for querying and segmenting event data.

Overview

This MCP server enables AI assistants and other MCP clients to interact with the Amplitude Analytics API, allowing them to:

  • Query event data with filters

  • Perform advanced segmentation with breakdowns

  • Access event data through structured resources

Installation

{
  "mcpServers": {
    "amplitude": {
      "command": "npx",

      ]
    }
  }

Available Tools

1. query_events

Basic event querying with filters.

Parameters:

    • eventType (string): Type of event

    • propertyFilters (array, optional): Filters for event properties

  • start (string): Start date in YYYYMMDD format

  • end (string): End date in YYYYMMDD format

  • interval (string, optional): Grouping interval (day, week, month)

  • groupBy (string, optional): Grouping dimension

Example:

{
  "events": [
    {
      "eventType": "user_login",
      "propertyFilters": [
        {
          "propertyName": "device_type",
          "value": "mobile",
          "op": "is"
        }
      ]
    }
  ],
  "start": "2023-01-01",
  "end": "2023-01-31",
  "interval": "day"
}

2. segment_events

Advanced event segmentation with breakdowns.

Parameters:

  • All parameters from query_events

  • filters (array, optional): Additional filters for segmentation

    • type (string): Filter type (property, event, user)

    • propertyName (string, optional): Name of the property

    • value (mixed, optional): Value to filter by

    • op (string, optional): Operator for comparison

  • breakdowns (array, optional): Breakdown dimensions

    • type (string): Breakdown type (event, user)

    • propertyName (string): Name of the property to break down by

Example:

{
  "events": [
    {
      "eventType": "purchase"
    }
  ],
  "start": "2023-01-01",
  "end": "2023-01-31",
  "interval": "week",
  "filters": [
    {
      "type": "user",
      "propertyName": "country",
      "value": "US",
      "op": "is"
    }
  ],
  "breakdowns": [
    {
      "type": "user",
      "propertyName": "device_type"
    }
  ]
}

Available Resources

amplitude_events

Access event data for a specific event type and date range.

URI Format:

amplitude://events/{eventType}/{start}/{end}

Example:

amplitude://events/user_login/2023-01-01/2023-01-31

TDQS

D1/5.0
Behavior1/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Tool has no description.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness1/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Tool has no description.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Tool has no description.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Tool has no description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose1/5

Does the description clearly state what the tool does and how it differs from similar tools?

Tool has no description.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines1/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Tool has no description.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

D1.5/5.0

Scored across 2 tools

Disambiguation3/5

The tool names suggest different operations ('query' vs 'segment'), but the lack of descriptions prevents clear disambiguation. An agent might still select incorrectly without more context.

Naming Consistency4/5

Both tools use a consistent snake_case verb_noun pattern ('query_events', 'segment_events'), which is clear and predictable.

Tool Count2/5

Only 2 tools is insufficient for a service like Amplitude, which typically offers a wide range of analytics operations. The surface feels too thin.

Completeness2/5

The set is severely incomplete for any meaningful analytics workflow. Missing CRUD operations for events, user properties, and other essential endpoints.
