AI agents call create_checksum to retrieve information from Run Iq without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Computing a SHA-256 checksum is a read-only, deterministic operation that takes input data and produces a hash. It does not create, modify, delete, or transmit any data. The blast radius of misuse is essentially zero — at worst it wastes compute cycles.
From the tool's definition 'Compute SHA-256 checksum for parameters or a full rule object' — this is a pure computational/hashing operation with no side effects
Attacks that exploit this kind of access
Compute SHA-256 checksum for parameters or a full rule object. It is categorised as a Read tool in the Run Iq MCP Server, which means it retrieves data without modifying state.
Register the Run Iq MCP server in PolicyLayer and add a rule for create_checksum: 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 Run Iq. Nothing to install.
create_checksum 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 create_checksum 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 create_checksum. 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.
create_checksum is provided by the Run Iq MCP server (run-iq/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
