| Capability Hierarchy App Resolver (sn_ea_mcp_server.ea.capability_hierarchy_resolver) | Resolves business capability-to-application mappings by traversing the capability hierarchy, identifying which applications support each capability at every level. |
| Related Entities Resolver (sn_ea_mcp_server.ea.related_entities_resolver) | Retrieves entities related to a specified business application or architectural element. Returns dependencies and relationships across the EA data model, and traces multi-level impact and dependency chains from a single configuration item. |
| Get EA Business App Insights (sn_ea_mcp_server.ea.get_ea_business_app_insights) | Generates Now Assist AI-generated insights for a business application, including health scores, rationalization signals, and strategic recommendations. |
| Diagram change analysis (sn_ea_mcp_server.diagram_change_analysis) | Compares two versions of an EA diagram and summarizes the architectural changes between them, or summarizes a single diagram version. Available only when the Enterprise Modeling and Visualization plugin is installed. |
| Artifact Resolver (sn_ea_mcp_server.ea.artifact_resolver) | Identifies the architectural artifacts, such as documents and diagrams, that are linked to an EA entity, and the entities that a given artifact documents. |

Note:  
* A tool's annotation defines the operations that the tool can perform on your instance data. All tools installed with the application have the readOnlyHint annotation, which means they retrieve data but don't create, update, or delete records. To view a tool's annotation, open the tool record in the MCP Server Console Console and see the Annotations field.
* The EA MCP server is also associated with the Enterprise Graph tool (sn_mcp_server.enterprise_graph). This tool is provided by the platform and isn't installed with the application.
