Part of the Mapbox MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call poi_search_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 poi_search_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.

Find one specific place or brand location by its proper name or unique brand. Use only when the user's query includes a distinct title (e.g., "The Met", "Starbucks Reserve Roastery") or a brand they want all nearby branches of (e.g., "Macy's stores near me"). Do not use for generic place types such as 'museums', 'coffee shops', 'tacos', etc. Setting a proximity point is strongly encouraged for more relevant results. Always try to use a limit of at least 3 in case the user's intended result is not the first result. Supports both JSON and text output formats.. It is categorised as a Read tool in the Mapbox MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for poi_search_tool. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Mapbox MCP server.
poi_search_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 poi_search_tool 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 poi_search_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.
poi_search_tool is provided by the Mapbox MCP server (Waldzell-Agentics/mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
