AI agents call get_file_blobs 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 | Yes | Branch, tag, or commit SHA. |
since | string | — | ISO 8601 timestamp to retrieve the file as it existed at that time. |
filePath | string | Yes | File path within the repository. |
repositoryId | string | Yes | Repository numeric ID or full path such as org/repo. |
organizationId | string | — | Yunxiao organization ID. When omitted, the server uses the user's default organization. |
Parameters from the server's own tool schema.
This tool retrieves data (file content and metadata) from a repository without creating, modifying, deleting, or executing any operations. It is a straightforward read operation with minimal blast radius if misused—an AI agent could only retrieve existing files without harming systems or data integrity.
From the tool's definition Tool description states 'Get file content and metadata from a CodeUp repository' with instruction to 'Use list_files to discover valid file paths.' The verb 'Get' and explicit retrieval of file content and metadata indicate a read-only operation with no…

Attacks that exploit this kind of access
Get file content and metadata from a CodeUp repository. Use list_files to discover valid file paths. It is categorised as a Read tool in the Yunxiao MCP Server, which means it retrieves data without modifying state.
get_file_blobs accepts 5 parameters: ref, since, filePath, repositoryId, organizationId. Required: ref, filePath, 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 get_file_blobs: 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.
get_file_blobs 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_file_blobs 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_file_blobs. 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_file_blobs 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.
