Get logs for transactions matching the provided topic
AI agents call getTopicTransactionLogs to retrieve information from Somnia 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 and queries transaction logs from the Somnia blockchain based on topic filters. It has no side effects, does not modify data, and does not execute commands or trigger external operations. It is purely informational in nature, consistent with other sibling tools on this server that retrieve blockchain data (getBlockHeights, getBlockTransactions, getERC20Balance, etc.).
From the tool's definition Tool name is 'getTopicTransactionLogs' and description states 'Get logs for transactions matching the provided topic' — this is a retrieval/query operation with no modification capability.

Register the Somnia MCP Server MCP server in PolicyLayer and add a rule for getTopicTransactionLogs: 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 Somnia MCP Server. Nothing to install.
getTopicTransactionLogs 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 getTopicTransactionLogs 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 getTopicTransactionLogs. 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.
