Community MCP plugin
A third-party-authored MCP server packaged into a Stallari pack and invokable from skills. Covers most external API service integrations the community contributes to the ecosystem.
Distinct from a blade: community plugins are not authored by Groupthink Dev. and sit at the Community trust tier (or User / Imported if signed by the user or unrecognised). See Packs and trust for the tier model and the trust posture differences.
