AI agents invoke buffer_features to trigger actions in ArcGIS Pro Bridge MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool runs a geoprocessing operation (Buffer analysis) in the ArcGIS Pro/ArcPy environment, which creates new output feature data. It spans Write and Execute categories, but since it triggers an external geoprocessing operation in ArcPy whose effects depend on arguments (input features, buffer distance, etc.), Execute is the most appropriate category.

Documented attack patterns abuse exactly the kind of access buffer_features 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 buffer_features:
{
"version": "1",
"default": "deny",
"tools": {
"buffer_features": {
"limits": [
{
"counter": "buffer_features_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}buffer_features stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. 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 buffer_features: 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.
buffer_features is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the buffer_features 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 buffer_features. 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.
buffer_features 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.
