AI agents call health_check 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.
A health check is a read-only diagnostic operation that queries the status of the MCP server and ArcGIS environment without modifying state, executing arbitrary code, or triggering external processes. It is informational only, making it a Read-category tool with low severity since misuse cannot cause data loss, corruption, or unwanted actions.
From the tool's definition Tool name 'health_check' and description indicating it 'returns lightweight health check' to assess MCP and ArcGIS environment availability. The tool performs a diagnostic query with no side effects, modifications, or external operations.
Documented attack patterns abuse exactly the kind of access health_check 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 health_check:
{
"version": "1",
"default": "deny",
"tools": {
"health_check": {}
}
}health_check is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the ArcGIS Pro Bridge MCP Server MCP server in PolicyLayer and add a rule for health_check: 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.
health_check 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 health_check 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 health_check. 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.
health_check 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.
