get_dynamic_gis · ArcGIS MCP: Risk & Policy

WHAT IT DOES

What get_dynamic_gis does on ArcGIS MCP

AI agents invoke get_dynamic_gis to trigger actions in ArcGIS MCP. 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.

WHY IT NEEDS A POLICY

Why get_dynamic_gis needs a policy

Dynamically loading and invoking modules, classes, and functions at runtime constitutes code execution. Even if framed as 'get', the ability to dynamically resolve and potentially call arbitrary ArcGIS Python API functions exposes significant execution risk. The blast radius is high because an AI agent could invoke destructive or privileged API functions through this dynamic dispatch mechanism.

From the tool's definition 'obtiene... función dinámicamente usando ArcGIS API for Python' — dynamically retrieves modules, classes, properties, or functions via the ArcGIS Python API, implying dynamic code execution or reflection

Verdict

get_dynamic_gis Rate-limited

get_dynamic_gis 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches ArcGIS MCP, so you can run agents against it safely.

FAQ

Questions about get_dynamic_gis

What does the get_dynamic_gis tool do? +

Obtiene: modulo, clase, propiedad o función dinámicamente usando ArcGIS API for Python. It is categorised as a Execute tool in the ArcGIS MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on get_dynamic_gis? +

Register the ArcGIS MCP server in PolicyLayer and add a rule for get_dynamic_gis: 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 MCP. Nothing to install.

What risk level is get_dynamic_gis? +

get_dynamic_gis is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit get_dynamic_gis? +

Yes. Add a rate_limit block to the get_dynamic_gis 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.

How do I block get_dynamic_gis completely? +

Set action: deny in the PolicyLayer policy for get_dynamic_gis. 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.

What MCP server provides get_dynamic_gis? +

get_dynamic_gis is provided by the ArcGIS MCP server (renemorenow/arcgis-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
