AI agents call inspect_gdb to retrieve information from ArcGIS Pro Bridge MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves information about geodatabase structure and metadata (feature classes, fields, spatial references). It returns Resource URIs for reference but does not create, modify, delete, or execute code. The action is purely informational and read-only, consistent with the Read category.
From the tool's definition Tool description states it 'inspects' GDB feature classes, fields, and spatial references and returns Resource URIs. The verb 'inspect' and the return of read-only metadata indicates data retrieval with no modification or side effects.
Documented attack patterns abuse exactly the kind of access inspect_gdb gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ArcGIS Pro Bridge MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for inspect_gdb:
{
"version": "1",
"default": "deny",
"tools": {
"inspect_gdb": {}
}
}inspect_gdb is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

检查 GDB 的要素类、字段与空间参考，并返回对应 Resource URI。. It is categorised as a Read tool in the ArcGIS Pro Bridge MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ArcGIS Pro Bridge MCP Server MCP server in PolicyLayer and add a rule for inspect_gdb: 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 ArcGIS Pro Bridge MCP Server. Nothing to install.
inspect_gdb 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 inspect_gdb 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 inspect_gdb. 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.
inspect_gdb is provided by the ArcGIS Pro Bridge MCP Server MCP server (sangwxx/arcgis-pro-bridge-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
