webmap_get
AI agents call webmap_get to retrieve information from ArcGIS MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'get' suffix strongly suggests a query or retrieval operation with no side effects. Although the description is empty (lowering confidence slightly), the naming convention and context within an ArcGIS server managing items and data support classification as a Read operation. No evidence suggests creation, modification, deletion, or execution of arbitrary operations.
From the tool's definition Tool name 'webmap_get' indicates a retrieval operation. The suffix '_get' conventionally denotes read-only data fetching.
Attacks that exploit this kind of access
webmap_get. It is categorised as a Read tool in the ArcGIS MCP MCP Server, which means it retrieves data without modifying state.
Register the ArcGIS MCP server in PolicyLayer and add a rule for webmap_get: 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.
webmap_get 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 webmap_get 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 webmap_get. 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.
webmap_get 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.
