Get transaction details by hash.
AI agents call transaction to retrieve information from Mcp Services without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves existing transaction data from a blockchain by its hash identifier. The verb 'Get' and the read-only nature of querying transaction details (no side effects, no state modifications, no code execution, no financial transfers) clearly places this in the Read category. The low severity reflects that querying public blockchain transaction data poses minimal risk even if misused by an agent.
From the tool's definition Tool name 'transaction' with description 'Get transaction details by hash' indicates a query operation that retrieves blockchain transaction information without modifying state.
Attacks that exploit this kind of access
Get transaction details by hash. It is categorised as a Read tool in the Mcp Services MCP Server, which means it retrieves data without modifying state.
Register the Mcp Services MCP server in PolicyLayer and add a rule for transaction: 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 Mcp Services. Nothing to install.
transaction 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 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. 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 is provided by the Mcp Services MCP server (san-npm/mcp-services). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
