# stx_query_transactions_by_contract Query transactions that interacted with a specific smart contract. Agent View of the PolicyLayer registry record for `stx_query_transactions_by_contract`. HTML page: https://policylayer.com/tools/markmhendrickson-mcp-server-bitcoin/stx-query-transactions-by-contract ## Facts - Tool: `stx_query_transactions_by_contract` - Server: Bitcoin wallet MCP server (`markmhendrickson/mcp-server-bitcoin`) — https://policylayer.com/tools/markmhendrickson-mcp-server-bitcoin.md - Homepage: https://github.com/markmhendrickson/mcp-server-bitcoin - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "stx_query_transactions_by_contract", "arguments": {} } } ``` ## Why stx_query_transactions_by_contract is rated Low This tool retrieves historical transaction data associated with a smart contract. It performs a read-only query operation that has no side effects, does not modify any blockchain state, does not execute code, and does not move funds. The query operation is purely informational and poses minimal risk if misused by an AI agent, as it cannot alter wallet state, execute transactions, or cause financial harm. From the tool's own definition: "Tool name contains 'query' and description states 'Query transactions' - a passive data retrieval operation with no modification, deletion, or execution of code." ## Use case AI agents call stx_query_transactions_by_contract to retrieve information from Bitcoin wallet MCP server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**.
