Bulk/mass operation — affects multiple targets
Part of the Ibge Br MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call ibge_malhas to retrieve information from Ibge Br 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 ibge_malhas 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.

Gets geographic meshes (maps) from IBGE in GeoJSON, TopoJSON, or SVG format. Features: - Meshes for Brazil, regions, states, municipalities - Different resolution levels (internal divisions) - Different quality levels - Formats: GeoJSON (data), TopoJSON (compact), SVG (image) Locality types: - "BR" or "1" = Entire Brazil - State abbreviation (e.g., "SP", "RJ") - State code (e.g., "35" for SP) - Municipality code (7 digits) Resolution (internal divisions): - 0 = Outline only - 2 = States - 5 = Municipalities Examples: - Brazil with states: localidade="BR", resolucao="2" - São Paulo with municipalities: localidade="SP", resolucao="5" - SVG format: localidade="BR", formato="svg". It is categorised as a Read tool in the Ibge Br MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for ibge_malhas. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Ibge Br MCP server.
ibge_malhas 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 ibge_malhas 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 ibge_malhas. 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.
ibge_malhas is provided by the Ibge Br MCP server (ibge-br-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
