Get detailed information about a specific Bitcoin UTXO (unspent transaction output) by its outpoint in the format
AI agents call output_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 performs a straightforward lookup of immutable blockchain data (a UTXO). It has no write, delete, execute, or financial capabilities—it simply retrieves and returns existing information. The blast radius is minimal since it cannot modify state, trigger actions, or move funds. Low severity appropriate for informational blockchain queries.
From the tool's definition Tool retrieves 'detailed information about a specific Bitcoin UTXO' and 'outpoint' by query parameters. The description indicates data retrieval with no modification capability.
Attacks that exploit this kind of access
Get detailed information about a specific Bitcoin UTXO (unspent transaction output) by its outpoint in the 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 output_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.
output_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 output_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 output_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.
output_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.
