AI agents call fetch to retrieve information from Yargı MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Based on context from sibling tools and server description, 'fetch' appears to retrieve legal documents from Turkish court and regulatory databases. This is a read-only operation with no side effects. Confidence is moderate (0.75) rather than high due to the empty description, but the tool name and server context make the classification clear.
From the tool's definition Tool named 'fetch' on a legal database server; sibling tools include 'get_anayasa_document_unified', 'get_bddk_document_markdown', 'get_danistay_document_markdown', etc., all of which are clearly retrieval operations.
Attacks that exploit this kind of access
fetch. It is categorised as a Read tool in the Yargı MCP MCP Server, which means it retrieves data without modifying state.
Register the Yargı 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 Yargı MCP. 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 Yargı MCP server (saidsurucu/yargi-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
