fetch
AI agents call fetch to retrieve information from WebDAV MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool 'fetch' almost certainly retrieves file content from the WebDAV file system. Despite the empty description, the name and sibling tools (particularly directory_tree and get_file_info which are clearly read operations) strongly suggest this is a read operation with no side effects. WebDAV fetch conventionally retrieves file contents.
From the tool's definition Tool named 'fetch' on a WebDAV server with CRUD operations; positioned among sibling tools that include read operations (directory_tree, get_file_info) and write/destructive operations (create_directory, edit_file, delete_entities).
Attacks that exploit this kind of access
fetch. It is categorised as a Read tool in the WebDAV MCP Server MCP Server, which means it retrieves data without modifying state.
Register the WebDAV MCP Server MCP server in PolicyLayer and add a rule for fetch: 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 WebDAV MCP Server. Nothing to install.
fetch 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 fetch 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 fetch. 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.
fetch is provided by the WebDAV MCP Server MCP server (masx200/mcp-webdav-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
