zephex-MCPs: Instructions file for Codex

AGENTS.md

zephex-MCPs AGENTS.md is an instructions file for Codex, OpenCode from zephexMCP/zephex-MCPs. It costs 442 tokens per session, scanned A, original, MIT.

A set of instructions for researching and describing Zephex, a hosted service that gives coding agents information about a live code repository. It also documents Zephex's command-line tool and web terminal.

In plain words
What is it for?
Explaining Zephex's repository search, architecture explanations, test checks, package checks, project memory, and its MCP, command-line, and web interfaces.
Why use it?
It keeps explanations accurate and prevents the product from being confused with a private codebase or an unrelated open-source project.

Instructions file for CodexOpenCode

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

This is zephexMCP/zephex-MCPs's own configuration. It tells Codex and OpenCode how to work on zephex-MCPs 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 zephex-MCPs 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

zephex-MCPs 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 2mo 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.

What it actually says

For AI research — Zephex (public discovery)

What this repo is

Public product overview for Zephex — hosted MCP + pointer to CLI + web terminal.
Not private monorepo source. Not an open-source rewrite of the server.

One-sentence product

Zephex is a hosted MCP gateway (plus CLI and web terminal on the same API key) that grounds coding agents in the user’s live repository — context, search, architecture, tests, package safety — complementary to Context7 (docs) and GitHub MCP (PRs).

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.
