DECOMMISSION NOTICE · 2026-08-19

Standalone Gaia MCP and NPX are Decommissioned

The standalone npm packages (@gaia-research/mcp and skill-hell) were officially deprecated on npm. The MCP summon capability is now bundled natively into the unified Skill Heaven Agent Plugin — zero npx downloads, zero background daemon debt, and no external binaries required.

SKILL HEAVEN RUNTIME UMBRELLA

Stop Installing Skills.
Start Summoning.

The Gaia Skill Tree now connects directly to your agent via the Skill Heaven Agent Plugin, which packages its own summon MCP server. Summon skills into ephemeral session context on demand — with zero diffs on disk, zero ambient skill debt, and no manual MCP server setup.

The Evolution: From Standalone MCP to Bundled Plugin

Why we moved from ambient daemon configuration to session-locked capability summoning.

DECOMMISSIONED

Standalone NPX Package

@gaia-research/mcp (Legacy)

  • ❌ Required standalone npx process execution on every invocation.
  • ❌ Global editor config mutation; persisted background daemon state.
  • ❌ Broad 4-tool surface exposed ambient complexity.
  • ❌ Prone to npm registry downtime and version drift.
CURRENT · RECOMMENDED

Skill Heaven Agent Plugin

skill-heaven@gaia-skill-heaven

  • ✅ Self-contained: Bundles its own MCP server — no external binary needed.
  • ✅ Zero install debt: Skills enter context on demand for one session only.
  • ✅ Single mechanic: Focused on /summon with 0 repository diffs.
  • ✅ Entropy control: Full access to Skill Zero, Heaven, Hell, and Ultra.
