AI agents call get_transaction to retrieve information from 0g without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves existing transaction information from the blockchain by hash. It is a read-only operation that does not create, modify, execute code, delete, or move funds. The low severity reflects minimal blast radius if misused—an AI agent retrieving transaction data poses no direct harm.
From the tool's definition Tool name 'get_transaction' and description 'Get transaction details by hash on 0G network' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
Get transaction details by hash on 0G network. It is categorised as a Read tool in the 0g MCP Server, which means it retrieves data without modifying state.
Register the 0g MCP server in PolicyLayer and add a rule for get_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 0g. Nothing to install.
get_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 get_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 get_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.
get_transaction is provided by the 0g MCP server (opencolin/0g-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
