List all instances with filtering and pagination support.
AI agents call get_instances to retrieve information from LeanIX MTM MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves instance data without creating, modifying, deleting, executing code, or affecting financial state. It is a straightforward data query operation typical of read-only API access, posing minimal risk even if misused by an AI agent.
From the tool's definition Tool name 'get_instances' and description 'List all instances with filtering and pagination support' indicate a query/retrieval operation with no side effects. The server is described as providing 'read-only access' to the LeanIX MTM API.
Attacks that exploit this kind of access
List all instances with filtering and pagination support. It is categorised as a Read tool in the LeanIX MTM MCP Server MCP Server, which means it retrieves data without modifying state.
Register the LeanIX MTM MCP Server MCP server in PolicyLayer and add a rule for get_instances: 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 LeanIX MTM MCP Server. Nothing to install.
get_instances 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 get_instances 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 get_instances. 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.
get_instances is provided by the LeanIX MTM MCP Server MCP server (tomgutt/leanix-mtm-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
