Get the raw hexadecimal representation of a specific Bitcoin block by its hash or height. This provides the complete serialized block data in hexadecimal format.
AI agents call block_raw_hex_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 public blockchain data (block hex encoding) without any side effects. It does not create, modify, delete, execute code, or involve financial operations. The blast radius of misuse is minimal—an agent could only fetch excessive data or cause minor resource exhaustion on the API endpoint, which is typical of read operations.
From the tool's definition Tool name contains 'get' and description states it 'Get[s] the raw hexadecimal representation of a specific Bitcoin block' and 'provides the complete serialized block data in hexadecimal format'.
Attacks that exploit this kind of access
Get the raw hexadecimal representation of a specific Bitcoin block by its hash or height. This provides the complete serialized block data in hexadecimal format. 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_raw_hex_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_raw_hex_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_raw_hex_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_raw_hex_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_raw_hex_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.
block_raw_hex_get is one line of Satstream MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
