Generates a static map image from Mapbox Static Images API. Supports center coordinates, zoom level (0-22), image size (up to 1280x1280), various Mapbox styles, and overlays (markers, paths, GeoJSON). Returns PNG for vector styles, JPEG for raster-only styles.

AI agents call static_map_image_tool to retrieve information from Mapbox 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 static_map_image_tool 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.

Generates a static map image from Mapbox Static Images API. Supports center coordinates, zoom level (0-22), image size (up to 1280x1280), various Mapbox styles, and overlays (markers, paths, GeoJSON). Returns PNG for vector styles, JPEG for raster-only styles.. It is categorised as a Read tool in the Mapbox MCP Server, which means it retrieves data without modifying state.
Register the Mapbox MCP server in PolicyLayer and add a rule for static_map_image_tool: 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 Mapbox. Nothing to install.
static_map_image_tool 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 static_map_image_tool 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 static_map_image_tool. 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.
static_map_image_tool is provided by the Mapbox MCP server (Waldzell-Agentics/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
