AI agents call list_knowledge_types to retrieve information from EKMS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward read operation that enumerates metadata about the EKMS. It has no side effects, does not execute code, does not modify data, and poses minimal security risk. The blast radius of misuse is negligible — an agent could only learn what knowledge types exist, which is informational only.
From the tool's definition Tool name 'list_knowledge_types' and description indicate it 'lists all available knowledge types and their descriptions' — a retrieval operation that queries the knowledge base structure without modifying, executing, or deleting anything.

Register the EKMS MCP Server MCP server in PolicyLayer and add a rule for list_knowledge_types: 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 EKMS MCP Server. Nothing to install.
list_knowledge_types 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 list_knowledge_types 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 list_knowledge_types. 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.
list_knowledge_types is provided by the EKMS MCP Server MCP server (jihsin/ekms-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
