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 | $0.05588 | $0.05588 |
| Opus 5 | $0.02794 | $0.02794 |
| Sonnet 5 | $0.01118 | $0.01118 |
| Haiku 4.5 | $0.00559 | $0.00559 |
Grade A, and why
octoparse-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 12d 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 Agent Guide
This document is the unified working guide for AI coding agents in OctopusMCPServer.
It applies to:
- Codex
- Claude Code
- Gemini
- Any other AI agent that reads code, changes code, writes documentation, or resolves conflicts in this repository
This file is intended to be the foundation for future development of this project. An agent should be able to use it to quickly establish a consistent understanding of:
- what this project is
- what the current runtime architecture is
- what the project actually values
- which constraints must not be broken
- which files should be read first before different kinds of changes
- which direction should be preferred during merge conflict resolution
If this document conflicts with the current code, the current code wins. If this document becomes outdated, update it as part of the same change.
1. Project Identity
OctopusMCPServer is a TypeScript-based MCP server. It exposes Octoparse-related capabilities over HTTP for MCP clients.
This repository is not just a flat list of tools and not just a thin API wrapper. The current codebase includes several important responsibilities that must be treated as first-class architecture:
- an Express 5 HTTP server
- MCP over Streamable HTTP
- session creation, recovery, and deletion
- dual authentication entry points through JWT and API key
- request-scoped context built on
AsyncLocalStorage - downstream Octoparse API access and HTTP connection pooling
- tool middleware chains
- structured logging and secure error handling
- optional Redis-backed persistence
- LLM-oriented tool interface design
The core value of this repository is not only "making the API work." Its real value is:
- correctly implementing MCP protocol behavior
- correctly isolating authentication context across users and requests
- correctly recovering distributed sessions
- correctly converging complex business capabilities into tool interfaces that LLMs can understand, choose, and recover from
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.

octoparse-mcp AGENTS.md is an instructions file published in the GitHub repository octoparse/octoparse-mcp (1 stars, last pushed 1mo ago), licensed MIT. It adds 5,588 tokens to every session, about $0.0279 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
