Read data from a verified smart contract on the Rootstock blockchain by calling view/pure functions
AI agents call read-contract to retrieve information from RSK MCP Server - Rootstock Blockchain Tools without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves data from smart contracts without modifying state or executing side effects. View and pure functions in Solidity are explicitly read-only and cannot alter blockchain state. No financial, destructive, write, or execute capabilities are present—only data retrieval from the blockchain.
From the tool's definition Tool name is 'read-contract' and description states it 'Read[s] data from a verified smart contract...by calling view/pure functions'. View and pure functions are read-only operations with no state mutation.
Attacks that exploit this kind of access
Read data from a verified smart contract on the Rootstock blockchain by calling view/pure functions. It is categorised as a Read tool in the RSK MCP Server - Rootstock Blockchain Tools MCP Server, which means it retrieves data without modifying state.
Register the RSK MCP Server - Rootstock Blockchain Tools MCP server in PolicyLayer and add a rule for read-contract: 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 RSK MCP Server - Rootstock Blockchain Tools. Nothing to install.
read-contract 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 read-contract 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 read-contract. 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.
read-contract is provided by the RSK MCP Server - Rootstock Blockchain Tools MCP server (rsksmart/rsk-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
