List markdown files in a workspace knowledge directory.
AI agents call knowledge_list to retrieve information from Chisel Knowledge MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a directory listing operation, which is a read-only query that retrieves information about stored markdown files. It does not create, modify, delete, or execute any operations—it simply enumerates existing files in a knowledge workspace.
From the tool's definition Tool name 'knowledge_list' and description 'List markdown files in a workspace knowledge directory' indicate a retrieval/query operation with no side effects.
Attacks that exploit this kind of access
List markdown files in a workspace knowledge directory. It is categorised as a Read tool in the Chisel Knowledge MCP MCP Server, which means it retrieves data without modifying state.
Register the Chisel Knowledge MCP server in PolicyLayer and add a rule for knowledge_list: 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 Chisel Knowledge MCP. Nothing to install.
knowledge_list 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 knowledge_list 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 knowledge_list. 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.
knowledge_list is provided by the Chisel Knowledge MCP server (teknologika/chisel-knowledge-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
