Retrieve information about the last 100 inscribed Bitcoin Runes (first page). Use this to get an overview of the most recently created rune tokens on the Bitcoin blockchain.
AI agents call runes_latest_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 and queries Bitcoin blockchain data (runes information) with no side effects, no code execution, no data modification, and no irreversible actions. It is purely a data retrieval operation, consistent with other Read-category tools on this server (address_get, block_get, etc.). The blast radius of misuse is minimal—an AI agent could only retrieve publicly available blockchain data.
From the tool's definition Tool name 'runes_latest_get' and description 'Retrieve information about the last 100 inscribed Bitcoin Runes' indicates a read-only query operation that fetches historical blockchain data without modification or execution of commands.
Attacks that exploit this kind of access
Retrieve information about the last 100 inscribed Bitcoin Runes (first page). Use this to get an overview of the most recently created rune tokens on the Bitcoin blockchain. 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 runes_latest_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.
runes_latest_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 runes_latest_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 runes_latest_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.
runes_latest_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.
