AI agents call list_files to retrieve information from Yunxiao without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
ref | string | — | Branch, tag, or commit SHA. Defaults to the repository default branch when omitted. |

Parameters from the server's own tool schema.
The tool performs a read-only operation to list/explore repository structure. It retrieves information about files and directories without creating, modifying, deleting, or executing any code. This is a standard repository browsing operation with no side effects.
From the tool's definition Tool name 'list_files' and description 'List files and directories in a CodeUp repository tree. Use this to explore repository structure.' indicate retrieval of repository metadata with no modifications.

List files and directories in a CodeUp repository tree. Use this to explore repository structure. It is categorised as a Read tool in the Yunxiao MCP Server, which means it retrieves data without modifying state.
list_files accepts 5 parameters: ref, path, type, repositoryId, organizationId. Required: repositoryId. The full parameter table on this page comes from the server's own tool schema.
Register the Yunxiao MCP server in PolicyLayer and add a rule for list_files: 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 Yunxiao. Nothing to install.
list_files 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_files 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_files. 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_files is provided by the Yunxiao MCP server (@futuretea/yunxiao-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
