AI agents call transaction_summary to retrieve information from Blockscout MCP Server without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though transaction_summary only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access transaction_summary gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Get human-readable transaction summaries from Blockscout Transaction Interpreter. Automatically classifies transactions into natural language descriptions (transfers, swaps, NFT sales, DeFi operations) Essential for rapid transaction comprehension, dashboard displays, and initial analysis. Note: Not all transactions can be summarized and accuracy is not guaranteed for complex patterns.. It is categorised as a Read tool in the Blockscout MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Blockscout MCP Server MCP server in PolicyLayer and add a rule for transaction_summary: 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 Blockscout MCP Server. Nothing to install.
transaction_summary 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 transaction_summary 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 transaction_summary. 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.
transaction_summary is provided by the Blockscout MCP Server MCP server (https://server.smithery.ai/@blockscout/mcp-server/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
