Retrieve a specific SCIM resource by ID
AI agents call getResourceById to retrieve information from SCIM MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation to fetch a single resource from a SCIM API by its identifier. It has no side effects, makes no changes to data, and poses minimal risk even if misused—it would only expose existing data the requester might access anyway. This fits the 'Read' category for retrieval operations.
From the tool's definition Tool name 'getResourceById' and description 'Retrieve a specific SCIM resource by ID' indicate a query operation that retrieves data without modification.
Attacks that exploit this kind of access
Retrieve a specific SCIM resource by ID. It is categorised as a Read tool in the SCIM MCP Server MCP Server, which means it retrieves data without modifying state.
Register the SCIM MCP Server MCP server in PolicyLayer and add a rule for getResourceById: 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 SCIM MCP Server. Nothing to install.
getResourceById 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 getResourceById 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 getResourceById. 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.
getResourceById is provided by the SCIM MCP Server MCP server (limosa-io/mcp-scim). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
