# Access Enterprise Architecture data using MCP tools

Use MCP \(Model Context Protocol\) tools to query live Enterprise Architecture data—including business application insights, capability mappings, and rationalization data—from any MCP-compatible AI assistant.

## Before you begin

Ensure your MCP for Enterprise Architecture is connected to an AI assistant. For information, see [Connect the EA MCP server to an AI assistant](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/application-portfolio-management/connect-ea-mcp-server-to-ai-assistant.md).

Role required: sn\_mcp\_server.viewer, and either sn\_apm.apm\_read or sn\_apm.apm\_user

## About this task

When you send a message, the AI assistant selects the relevant MCP tool from the available tools and retrieves the requested EA data. For a list of available tools, see [Explore MCP for Enterprise Architecture](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/application-portfolio-management/exploring-ea-mcp-server.md).

**Note:** Claude is used as an example AI assistant. Steps may vary depending on the AI client you use.

## About this task

## Procedure

1.  Open the Claude application.

2.  Start a chat by sending a message such as `Show me the business applications that support the Finance capability`.

    The Capability Hierarchy App Resolver tool retrieves applications mapped to the specified capability and its child capabilities.

3.  Continue the conversation to retrieve additional data — for example, send `Show me insights for the first application`.

    The Get EA Business App Insights tool generates ServiceNow Otto powered insights for the specified business application.

4.  Continue the conversation with additional prompts to retrieve the data you need.

    Example prompts you can use:

    -   `Which applications are at risk based on rationalization scores?`—uses the App Rationalization Query tool.
    -   `What entities are related to Workday?`—uses the Related Entities Resolver tool.
    -   `What changed in this diagram compared to last month?`—uses the Diagram change analysis tool.
    -   `Which entities does the Procure to Pay architecture diagram document?`—uses the Artifact Resolver tool.
    -   `Which business capabilities are impacted if the PS ORA01 database fails?`—uses the Related Entities Resolver tool.
    For outcome-driven prompts that combine several tools, see [Example prompts for MCP for Enterprise Architecture](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/application-portfolio-management/ea-mcp-server-example-prompts.md).
