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 | $0.06802 | $0.06802 |
| Opus 5.5 | $0.02721 | $0.02721 |
| Sonnet 5.5 | $0.01360 | $0.01360 |
| Haiku 4.5 | $0.00680 | $0.00680 |
Grade A, and why
mcpcodeserver 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 986 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md - mcpcodeserver Project Structure
This document provides comprehensive guidance for Claude Code (claude.ai/code) and other AI agents when working with this codebase. It covers project structure, implementation details, development workflows, and testing strategies.
Project Overview
mcpcodeserver is an MCP (Model Context Protocol) proxy server that transforms tool calling into code generation. It connects to child MCP servers as a client, discovers their tools, and exposes two meta-tools that allow LLMs to generate and execute TypeScript code that calls those tools.
Key Innovation
Instead of the traditional pattern:
LLM → Tool Call 1 → LLM → Tool Call 2 → LLM → Tool Call 3 → LLM
This enables:
LLM → Generate Code → Execute Code (calls Tool 1, 2, 3 internally) → Result

Using with MCP Clients
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.

mcpcodeserver AGENTS.md is an instructions file published in the GitHub repository zbowling/mcpcodeserver (14 stars, last pushed 1y ago), licensed MIT. It adds 6,802 tokens to every session, about $0.0272 per session on Opus 5.5. 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 2026-08-30.
