get_description
AI agents call get_description to retrieve information from MCP Server Proto-OKN without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite the empty description lowering confidence slightly, the tool name and server context indicate a retrieval operation with no side effects. No evidence of data modification, deletion, execution, or financial operations. Classified as Read with low severity due to typical safe usage patterns for metadata retrieval on SPARQL endpoints.
From the tool's definition Tool name 'get_description' suggests retrieving metadata or documentation. No description provided, but within context of a SPARQL/knowledge graph server, 'get' operations are typically read-only queries.
Attacks that exploit this kind of access
get_description. It is categorised as a Read tool in the MCP Server Proto-OKN MCP Server, which means it retrieves data without modifying state.
Register the MCP Server Proto-OKN MCP server in PolicyLayer and add a rule for get_description: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MCP Server Proto-OKN. Nothing to install.
get_description is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_description rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_description. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_description is provided by the MCP Server Proto-OKN MCP server (sbl-sdsc/mcp-proto-okn). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
