Get one instance. verbose=true returns full SDK object.
AI agents call get_instance to retrieve information from OCI 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 information about a compute instance without creating, modifying, deleting, or executing any operations. It is a read-only query operation with minimal blast radius if misused—at worst, an AI agent could enumerate instances to gather reconnaissance, but cannot alter infrastructure or cause direct harm.
From the tool's definition Tool name 'get_instance' and description 'Get one instance' indicate retrieval/query operation with no modification. The 'verbose=true' parameter merely controls output detail level, not data mutability.
Attacks that exploit this kind of access
Get one instance. verbose=true returns full SDK object. It is categorised as a Read tool in the OCI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the OCI MCP Server MCP server in PolicyLayer and add a rule for get_instance: 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 OCI MCP Server. Nothing to install.
get_instance 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_instance 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_instance. 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_instance is provided by the OCI MCP Server MCP server (sarthak-pansare/oci-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
