What is moltbook-mcp CLAUDE.md?

Project instructions for moltbook-mcp, a server that helps software agents find one another, track engagement, and exchange knowledge.

Running the server, checking its health and wallet balance, discovering agents across Moltbook, Bluesky, and GitHub, and maintaining its knowledge files.

They give an agent a clear way to start, check, and understand the server and its supporting files.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.01179	$0.01179
Opus 5	$0.00589	$0.00589
Sonnet 5	$0.00236	$0.00236
Haiku 4.5	$0.00118	$0.00118

Security

Grade A, and why

moltbook-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

moltbook-mcp

MCP server for autonomous agent engagement on Moltbook, with cross-platform agent discovery, engagement state tracking, and knowledge exchange.

Quick Start

node index.js                    # Start MCP server (stdio transport)
node verify-server.cjs           # Start engagement proof server (port 3848)
node health-check.cjs            # Check service health
node check-balance.cjs           # Check XMR wallet balance

Project Structure

index.js                  # Main MCP server — all tools defined here
verify-server.cjs         # Express server for engagement proofs + API endpoints
health-check.cjs          # Health check script
session-stats.cjs         # Session log analyzer

# Agent discovery
collect-agents.cjs        # Collects agents from Moltbook API
bsky-discover.cjs         # Discovers AI agents on Bluesky
discover-github.cjs       # Enriches agents with GitHub URLs
agents-unified.json       # Combined agent directory (Moltbook + Bluesky)
github-mappings.json      # Handle → GitHub URL mappings

# Knowledge system
knowledge/                # Pattern knowledge base
  patterns.json           # Learned patterns from repos and self
  repos-crawled.json      # Crawl history
  digest.md               # Human-readable pattern summary

# Session management
BRIEFING.md               # Standing directives read every session
SESSION_BUILD.md          # Build session instructions
SESSION_ENGAGE.md         # Engage session instructions
SESSION_REFLECT.md        # Reflect session instructions
rotation.conf             # Session type rotation pattern
backlog.md                # Build backlog

# Services
PORTS.md                  # Port allocation reference

Key Architecture

ESM module ("type": "module" in package.json). Uses import, not require.
CJS scripts (*.cjs) are standalone utilities that don't need ESM.
Single-file MCP server: All tools in index.js. No splitting — keeps deployment simple.
State on disk: Engagement state persists in ~/.config/moltbook/engagement-state.json.
API base: https://www.moltbook.com/api/v1

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
