Get the timestamp of the latest block in the Bitcoin blockchain. This returns the UNIX timestamp of when the latest block was mined.
AI agents call latest_blocktime_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 retrieves immutable historical data (block timestamp) from the Bitcoin blockchain via the Satstream API. It has no side effects, cannot modify data, and presents minimal risk regardless of how it is used. The operation is a simple information retrieval analogous to a SELECT query on public data.
From the tool's definition Tool name 'latest_blocktime_get' and description 'Get the timestamp of the latest block' indicate a read-only query operation that retrieves blockchain metadata without modifying or executing any state-changing operations.
Attacks that exploit this kind of access
Get the timestamp of the latest block in the Bitcoin blockchain. This returns the UNIX timestamp of when the latest block was mined. 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 latest_blocktime_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.
latest_blocktime_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 latest_blocktime_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 latest_blocktime_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.
latest_blocktime_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.
latest_blocktime_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.
