Fetch full transaction detail (inputs, outputs, fee, size, confirmation status) for a given txid on mainnet/testnet/signet/liquid.
AI agents call get_transaction to retrieve information from Mcp Mempool Space without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves transaction information (inputs, outputs, fee, size, confirmation status) from a public blockchain explorer without creating, modifying, deleting, or executing any operations. It is a standard data retrieval operation with no blast radius if misused by an AI agent, as it cannot alter blockchain state or cause financial harm through querying alone.
From the tool's definition Tool name 'get_transaction' and description 'Fetch full transaction detail' indicate a read-only operation that retrieves and queries blockchain transaction data with no modifications or side effects.
Attacks that exploit this kind of access
Fetch full transaction detail (inputs, outputs, fee, size, confirmation status) for a given txid on mainnet/testnet/signet/liquid. It is categorised as a Read tool in the Mcp Mempool Space MCP Server, which means it retrieves data without modifying state.
Register the Mcp Mempool Space 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 Mcp Mempool Space. 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 Mcp Mempool Space MCP server (pipeworx-io/mcp-mempool-space). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
