Publish Nostr marketplace listings so agents can operate an automated store.
This MCP tool comes from the official registry and is open source, with no clear high-risk red flags in the provided material. However, it requires a Nostr private key, executes local code, and connects to user-configured Nostr relays, so it should be used with least privilege and isolation.
It requires environment variables such as NOSTR_PRIVATE_KEY, NOSTR_NIP46_URI, and NOSTR_RELAYS. NOSTR_PRIVATE_KEY is a highly sensitive credential that can be used to sign and publish Nostr events on behalf of the user; leakage could enable impersonation and abusive publishing.
No fixed remote host is listed, but the described function explicitly publishes Nostr marketplace events, and NOSTR_RELAYS indicates connections to user-specified relays. This means data is sent to configured Nostr network endpoints, which is a normal egress pattern for its stated purpose.
System checks indicate that the tool executes code / runs as a local MCP component, which is an inherent capability of such tools. The provided material does not show abnormal system privileges beyond its stated purpose of publishing marketplace listings, so this is caution rather than high risk.
Based on the available description, it primarily handles marketplace listing data to be published along with related Nostr configuration. There is no evidence of broad filesystem access, browser data access, system keychain access, or other clearly excessive permissions. SHOPSTR_CACHE_ENABLED suggests possible local caching, but the material does not show broad sensitive data read/write behavior.
It is distributed via the official registry and is open source, with updates within the past year—both are meaningful risk-reducing factors. Community adoption is currently low (0 stars) and the license is unspecified, which adds some maintainability/compliance uncertainty, but not enough on its own to constitute a high-risk red flag.
