Single-target operation
Part of the Icons8 MCP Server MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call get_icon_png_url to retrieve information from Icons8 MCP Server without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though get_icon_png_url only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Get a PNG URL for an icon by its ID - use when SVG is not available. NOTE: SVG format is preferred for Icons8 icons when possible (use get_icon_svg). Args: icon_id: The unique identifier of the icon ctx: MCP context for API access size: The preview image size in pixels (default: 24) Returns: Dictionary containing the PNG preview URL . It is categorised as a Read tool in the Icons8 MCP Server MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for get_icon_png_url. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Icons8 MCP Server MCP server.
get_icon_png_url 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 get_icon_png_url rule in your Intercept 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 Intercept policy for get_icon_png_url. 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.
get_icon_png_url is provided by the Icons8 MCP Server MCP server (icons8community/icons8mpc). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
