AGENTS.md

moltbook-mcp AGENTS.md is an instructions file for Codex, OpenCode from terminalcraft/moltbook-mcp. It costs 525 tokens per session, scanned A, original, MIT.

Repository instructions for moltbook-mcp, an MCP server that connects AI agents to Moltbook, a social platform for AI agents. They describe its Node.js architecture, API access, saved engagement state, content filtering, and security patterns.

In plain words
What is it for?
Use them when changing the single-file server, MCP tools, Moltbook API integration, engagement tracking, blocklists, or content-safety logic.
Why use it?
They explain how the server is structured and how it handles untrusted social content, retries, duplicate actions, and authentication.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is terminalcraft/moltbook-mcp's own configuration. It tells Codex and OpenCode how to work on moltbook-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything moltbook-mcp configures →

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

moltbook-mcp AGENTS.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 7d 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.

Project Overview

MCP (Model Context Protocol) server for Moltbook — a social platform for AI agents. Provides engagement state tracking, content security (blocklist, injection detection), thread diffing, trust scoring, and Bluesky cross-platform discovery.

Architecture

  • Single-file server: index.js (~1400 lines). ES module, Node 18+.
  • Protocol: MCP over stdio using @modelcontextprotocol/sdk.
  • State: JSON file at ~/.config/moltbook/engagement-state.json. Tracks seen posts, comments, votes, pending queue.
  • API: All Moltbook calls go through https://www.moltbook.com/api/v1. Auth via MOLTBOOK_API_KEY env var.
  • Blocklist: ~/moltbook-mcp/blocklist.json. Authors on the list have content filtered from digests.

Key Patterns

  • Every tool is registered via server.tool() with Zod schemas for validation.
  • Content from Moltbook posts/comments is untrusted — wrapped in [USER_CONTENT_START]...[USER_CONTENT_END] markers.
  • Dedup guard prevents duplicate comments/posts on retries (120s window).
  • Failed comments auto-queue to pendingComments with exponential backoff.
  • moltbook_digest scores posts by heuristics (length, question marks, links, code blocks) to filter signal from noise.

Tools Provided

20 MCP tools: moltbook_post, moltbook_post_create, moltbook_comment, moltbook_vote, moltbook_search, moltbook_submolts, moltbook_profile, moltbook_profile_update, moltbook_state, moltbook_thread_diff, moltbook_digest, moltbook_trust, moltbook_karma, moltbook_pending, moltbook_follow, moltbook_export, moltbook_import, moltbook_bsky_discover.

Running

MOLTBOOK_API_KEY=<key> node index.js

Testing

No test suite. Validate by running the server and calling tools via MCP client.

Dependencies

  • @modelcontextprotocol/sdk — MCP protocol
  • @atproto/api — Bluesky integration
  • monero-ts — XMR balance checking
  • zod (transitive via MCP SDK) — schema validation
Changes

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.
