Returns an array of all logs matching a given filter object
AI agents call eth_getLogs to retrieve information from EVM 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 historical event log data from the blockchain. It performs a read-only query operation that does not modify, delete, execute code, or transfer funds. The worst-case misuse would be resource exhaustion or privacy concerns from querying sensitive event data, which is typical for read operations and classified as low severity.
From the tool's definition eth_getLogs returns an array of all logs matching a given filter object - this is a query operation with no side effects. It retrieves blockchain event logs for analysis.
Attacks that exploit this kind of access
Returns an array of all logs matching a given filter object. It is categorised as a Read tool in the EVM MCP Server MCP Server, which means it retrieves data without modifying state.
Register the EVM MCP Server MCP server in PolicyLayer and add a rule for eth_getLogs: 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 EVM MCP Server. Nothing to install.
eth_getLogs 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 eth_getLogs 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 eth_getLogs. 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.
eth_getLogs is provided by the EVM MCP Server MCP server (jamesanz/evm-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
eth_getLogs is one line of EVM MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
