List all extracted concepts with optional filtering by category or search term.
AI agents call list_concepts to retrieve information from Concept Tracker without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and presents concept data with optional filtering but does not create, modify, delete, or execute operations. It has no side effects beyond data retrieval, fitting the Read category definition (search, list, get, fetch). The severity is low as misuse would only expose existing internal knowledge base data rather than causing system damage or data loss.
From the tool's definition Tool name 'list_concepts' and description 'List all extracted concepts with optional filtering' indicate a query operation that retrieves and displays existing data without modification.
Attacks that exploit this kind of access
List all extracted concepts with optional filtering by category or search term. It is categorised as a Read tool in the Concept Tracker MCP Server, which means it retrieves data without modifying state.
Register the Concept Tracker MCP server in PolicyLayer and add a rule for list_concepts: 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 Concept Tracker. Nothing to install.
list_concepts 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_concepts 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_concepts. 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_concepts is provided by the Concept Tracker MCP server (liwengggou/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
