Satoshi API — Bitcoin Intelligence

Security checks across malware telemetry and agentic risk

Overview

This is a straightforward Bitcoin lookup skill that calls bitcoinsapi.com, with the main caveat that address lookups disclose the queried address to that service.

Install only if you are comfortable using bitcoinsapi.com as the data provider. Avoid querying Bitcoin addresses you consider private or sensitive, because those lookups will be sent to that external service along with normal request metadata.

MCP Least Privilege
Confidence
96% confidence
Finding
The skill clearly relies on outbound network access to query the Satoshi API, but the manifest does not declare any corresponding permission. This creates a transparency and policy-enforcement gap: users and hosts cannot accurately assess or restrict the skill’s external data access, and a future code change could reuse that undeclared network capability for broader exfiltration or tracking.

Missing User Warnings

Medium
Confidence
93% confidence
Finding
The address command transmits a user-supplied Bitcoin address to a third-party service via `get(f"/address/{address}")`, which exposes potentially sensitive financial metadata and user interest to an external provider. While a Bitcoin address is not a secret in the cryptographic sense, querying it can reveal watchlists, operational interest, or correlate users and workflows, and the skill does not provide a clear privacy warning or require consent before disclosure.
