Returns the number of transactions in the last 24 hours
AI agents call get_24h_tx_count to retrieve information from MCP Blockchain Query Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical transaction count statistics from the Bitcoin blockchain without modifying, executing, or affecting any state. It is purely informational and poses minimal risk if queried by an AI agent, as it cannot cause unintended consequences beyond returning blockchain statistics.
From the tool's definition Tool name 'get_24h_tx_count' and description 'Returns the number of transactions in the last 24 hours' indicate a data retrieval operation with no side effects. The verb 'Returns' and the passive data query nature align with read-only blockchain data access.

Returns the number of transactions in the last 24 hours. It is categorised as a Read tool in the MCP Blockchain Query Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Blockchain Query Server MCP server in PolicyLayer and add a rule for get_24h_tx_count: 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 Blockchain Query Server. Nothing to install.
get_24h_tx_count 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_24h_tx_count 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_24h_tx_count. 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_24h_tx_count is provided by the MCP Blockchain Query Server MCP server (pavel-bc/mcp-blockchain-query). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
