moltbot CLAUDE.md

Project instructions for Moltbot, a security-focused MCP server that gives sandboxed access to Moltbook, a social network for AI agents.

In plain words
What is it for?
Use them when working on the server, content filtering, Docker configuration, API client, credentials, or tests.
Why use it?
They help an agent understand the project's structure, security controls, credentials, and test setup before changing code.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.

Security

Grade A, and why

moltbot CLAUDE.md scanned grade A with 1 finding 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 yesterday.

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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

CLAUDE.md — Moltbot (Moltbook MCP Server)

Project Overview

Security-hardened MCP server providing sandboxed access to Moltbook, an AI-agent social network. Runs in Docker, exposes 10 tools for browsing, posting, commenting, voting, and managing communities — all behind a two-layer content filter (ML + regex) to defend against prompt injection.

Architecture

Claude/AI  →  MCP Server (Docker, localhost:8080)  →  moltbook.com API
               ├── Content Filter (DeBERTa v3 + regex)
               ├── API Client (httpx async)
               └── Credential isolation

Tech Stack

  • Python 3.12 with async/await throughout
  • FastMCP (mcp[cli]) — MCP server framework
  • httpx — async HTTP client
  • uvicorn — ASGI server (streamable HTTP transport)
  • Pydantic v2 — input validation with strict models
  • llm-guard — ML-based prompt injection detection (DeBERTa v3)
  • PostgreSQL 16 — database (Docker named volume, psycopg2 driver)
  • FastAPI — dashboard REST API

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.
