Get the current block height of the Bitcoin blockchain. This returns the height of the latest block that has been processed.
AI agents call block_count_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.
block_count_get retrieves read-only blockchain metadata (current block height). No state changes, no code execution, no external side effects—only data retrieval. This is the lowest-risk category and has minimal blast radius if misused by an AI agent.
From the tool's definition The tool description states it 'returns the height of the latest block that has been processed.' This is a pure query operation that retrieves blockchain state information without modifying, executing code, or causing side effects.
Attacks that exploit this kind of access
Get the current block height of the Bitcoin blockchain. This returns the height of the latest block that has been processed. 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_count_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_count_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_count_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_count_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_count_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.
