Get detailed information about a specific Bitcoin block by its hash or height. Use this to retrieve block header data, transaction IDs, and mining details.
AI agents call block_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 purely queries and retrieves immutable blockchain data. It performs a read-only operation with no side effects, no code execution, and no ability to modify or delete data. The blockchain is publicly readable, making unauthorized data access a minimal security concern. The low severity reflects that misuse would only result in information disclosure of publicly available data.
From the tool's definition Tool description explicitly states 'Get detailed information about a specific Bitcoin block' and lists only retrieval operations: 'retrieve block header data, transaction IDs, and mining details.' No modification, deletion, execution, or financial transaction…
Attacks that exploit this kind of access
Get detailed information about a specific Bitcoin block by its hash or height. Use this to retrieve block header data, transaction IDs, and mining details. 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 block_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.
block_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 block_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 block_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.
block_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.
