MCP Server Catalog (plugin_type=mcp)

A directory of servers compatible with Anthropic's Model Context Protocol. Hosts register MCP servers from the catalog to expose additional tool sets in the Tool Registry as source='mcp'. Registration info is kept in ~/.lvis/mcp/servers.json.

What Is MCP?

Model Context Protocol — an open spec proposed by Anthropic defining "how an LLM calls an external server's tools/resources/prompts through a standard interface." Besides native plugins, the LVIS host can register MCP servers to easily bring in additional tools.

Registration Flow

Fire the lvis://mcp-login/<slug> deeplink from the Storefront (PluginDetailPage:178), or enter the endpoint directly.
The host performs an MCP handshake to fetch server metadata / tool list, then stores metadata under ~/.lvis/mcp/<slug>/.
Registers into ~/.lvis/mcp/servers.json (boot.ts:1012-1016).
Registered in the Tool Registry as source='mcp'. The reviewer classifies it as medium RiskLevel by default.

RiskLevel for MCP tools

Tools from external MCP servers default to medium. Even if the publisher supplies risk metadata, it gets reclassified at the admin stage. Exposure as auto-executable (low) requires explicit admin approval.
