Get a specific schema by its ID.
AI agents call rossum_get_schema to retrieve information from Rossum 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 schema data by ID without any ability to modify, delete, or execute operations. It is a straightforward query operation with no side effects. The read-only nature of the server and analysis-only purpose further confirm this is a simple data retrieval with minimal risk if misused.
From the tool's definition Tool description explicitly states 'Get a specific schema by its ID.' Server description confirms 'read-only access to Rossum API resources' for 'analysis purposes.' Name and description both indicate retrieval without modification.
