列举 TOS 对象
AI agents call tos_list_objects to retrieve information from TOS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool lists objects in Volcengine's TOS (Tencent Object Storage equivalent). Listing operations are purely informational reads that retrieve metadata about existing objects without creating, modifying, deleting, or executing anything.
From the tool's definition Tool name 'tos_list_objects' with description '列举 TOS 对象' (enumerate/list TOS objects). This is a listing/query operation on object storage with no side effects.

列举 TOS 对象. It is categorised as a Read tool in the TOS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the TOS MCP Server MCP server in PolicyLayer and add a rule for tos_list_objects: 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 TOS MCP Server. Nothing to install.
tos_list_objects 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 tos_list_objects 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 tos_list_objects. 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.
tos_list_objects is provided by the TOS MCP Server MCP server (jneless/tos-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
