List all capabilities (resources, tools, and prompts) available in this server
AI agents call capabilities_tool to retrieve information from Reltio MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates metadata about available resources, tools, and prompts. It is a passive information lookup with no ability to modify, delete, or execute actions. It corresponds to the 'Read' category as it only queries and returns information without affecting any data or triggering operations.
From the tool's definition Tool name 'capabilities_tool' with description 'List all capabilities (resources, tools, and prompts) available in this server' performs a read-only query/discovery operation with no side effects.
