Get information about the last 100 Bitcoin blocks. Use this for obtaining an overview of recent blockchain activity including block heights, hashes, and timestamps.
AI agents call blocks_get to retrieve information from Satstream MCP 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 blockchain data without side effects. It only queries and returns information about recently mined blocks. There is no capability to modify data, execute code, delete records, or affect financial transactions. The operation is read-only and safe to expose to an AI agent.
From the tool's definition Tool description states 'Get information about the last 100 Bitcoin blocks' and mentions 'obtaining an overview of recent blockchain activity including block heights, hashes, and timestamps.' This is a data retrieval operation with no modification, deletion,…
Attacks that exploit this kind of access
Get information about the last 100 Bitcoin blocks. Use this for obtaining an overview of recent blockchain activity including block heights, hashes, and timestamps. It is categorised as a Read tool in the Satstream MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Satstream MCP Server MCP server in PolicyLayer and add a rule for blocks_get: 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 Satstream MCP Server. Nothing to install.
blocks_get 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 blocks_get 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 blocks_get. 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.
blocks_get is provided by the Satstream MCP Server MCP server (satstream/ss-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
