url_decode
AI agents call url_decode to retrieve information from Malware Analysis MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
URL decoding is a reversible, read-only data transformation operation that converts URL-encoded strings to their original form. It retrieves or parses data without creating, modifying, deleting, or executing external operations. Context confirms this is part of a malware analysis suite focused on defensive security research and data transformation.
From the tool's definition Tool name 'url_decode' indicates URL decoding; sibling tools include 'base64_decode', 'base64_encode', 'entropy', suggesting data transformation and analysis utilities for defensive security research. No description provided.

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