wsl_list_tags
AI agents call wsl_list_tags to retrieve information from Pypi:wsl Envidat without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool appears to list available tags from the WSL/EnviDat environmental database. Listing operations retrieve metadata without modification, deletion, or execution of code. The empty description lowers confidence slightly, but the naming pattern and server context (a read-only research data service) indicate this is a benign data retrieval operation with minimal blast radius.
From the tool's definition Tool name 'wsl_list_tags' indicates a listing/retrieval operation. Description is empty, but the sibling tools on this server (wsl_list_organizations, wsl_search, wsl_get_*) are all read-only query operations against environmental datasets.
Attacks that exploit this kind of access
wsl_list_tags. It is categorised as a Read tool in the Pypi:wsl Envidat MCP Server, which means it retrieves data without modifying state.
Register the Pypi:wsl Envidat MCP server in PolicyLayer and add a rule for wsl_list_tags: 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 Pypi:wsl Envidat. Nothing to install.
wsl_list_tags 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 wsl_list_tags 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 wsl_list_tags. 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.
wsl_list_tags is provided by the Pypi:wsl Envidat MCP server (pypi:wsl-envidat-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
