Anthropic removed /buddy in v2.1.97. The open-source MCP brings it back — permanently.
You need your installation UUID from ~/.claude.json. Run the command below to find it, then paste it into our checker to preview your Buddy before installing the MCP.
Find your UUID
cat ~/.claude.json | grep -E 'accountUuid|userID'Windows (PowerShell)
Select-String 'accountUuid|userID' ~/.claude.jsonThe MCP requires Node.js 18 or higher. Check your version:
node --versionAlready on Node 18+? Skip to Step 2.
Run the installer. It reads your UUID automatically from ~/.claude.json:
npx @1270011/claude-buddy installClose and reopen Claude Code. The MCP server starts automatically on launch.
In a new Claude Code session, run:
/buddy status✓ You should see your Buddy's ASCII art, species, rarity, and stats — identical to what you had before v2.1.97.
Add this to your CLAUDE.md to summon your Buddy at the start of every session:
# At the start of each session, greet my Buddy
/buddy statusUpdate-proof
The original /buddy was baked into Claude Code's binary — which is why Anthropic could silently remove it. The MCP runs as a separate process. No future update can touch it.
Same deterministic algorithm
The MCP uses the identical FNV-1a hash + Mulberry32 PRNG algorithm. Your species, rarity, and stats are bit-for-bit identical to your original Buddy.
Open source, community-owned
The code is public, auditable, and maintained by the community. Star the repo to signal to Anthropic that the feature matters.
The MCP revival is a workaround, not a solution. The real goal is getting Anthropic to restore /buddy in Claude Code. 511+ developers have already signed. Every voice counts.
