Get the value stored at a specific storage position in a contract
AI agents call get_storage_at to retrieve information from Monad 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 smart contract storage state without modifying it. It is a read-only query operation with no side effects, fitting the 'Read' category. The low severity reflects that retrieving contract storage data poses minimal risk even if misused by an agent — it only exposes already-public blockchain data.
From the tool's definition Tool name is 'get_storage_at' and description states 'Get the value stored at a specific storage position in a contract' — uses 'Get' verb indicating retrieval with no modification capability.
Attacks that exploit this kind of access
Get the value stored at a specific storage position in a contract. It is categorised as a Read tool in the Monad MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Monad MCP Server MCP server in PolicyLayer and add a rule for get_storage_at: 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 Monad MCP Server. Nothing to install.
get_storage_at 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_storage_at 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_storage_at. 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_storage_at is provided by the Monad MCP Server MCP server (tairon-ai/monad-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
