## Common questions

### What is the Muse Marketplace MCP server?

Muse Marketplace is an MCP server listed in the public MCP registry as io.github.CloudCorpRecords/muse-marketplace. Open marketplace and registry for shareable Muse assets: avatars, personas, voices, and bundles. This page covers its npm package (@reneturcios/muse-marketplace).

### Is the Muse Marketplace MCP server safe to use?

Muse Marketplace scores 65 out of 100 on VerifyMCP. We recorded 1 known advisory against it as of 5 November 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Muse Marketplace MCP server expose?

Muse Marketplace exposes 5 tools: marketplace_search, marketplace_list, marketplace_show, marketplace_validate, marketplace_install. Their descriptions and schemas cost roughly 240 tokens of context every time the server is loaded.

### Is the Muse Marketplace MCP server still maintained?

Muse Marketplace is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Muse Marketplace MCP server under?

Muse Marketplace declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Muse Marketplace MCP server?

VerifyMCP ran 15 checks on Muse Marketplace, covering Malware scan, Known CVEs, Install scripts, Dependency health and 11 more. One item could not be completed, a gap on our side rather than a finding about Muse Marketplace: Stability. One category scores 0 for that reason, because we only credit what we can confirm. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
