mcp-server: Instructions file for Codex

AGENTS.md

mcp-server AGENTS.md is an instructions file for Codex, OpenCode from kubeflow/mcp-server. It costs 2,122 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for contributors, maintainers, and AI agents working on kubeflow/mcp-server. They describe the project's structure, development rules, and expectations for safe, minimal changes.

In plain words
What is it for?
Finding the right development commands, understanding the repository layout, following testing and dependency rules, and preserving existing MCP tool and error-handling conventions.
Why use it?
They help agents understand the repository before editing it and avoid bypassing tests, changing protected interfaces, or introducing inconsistent code.

Instructions file for CodexOpenCode

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

This is kubeflow/mcp-server's own configuration. It tells Codex and OpenCode how to work on mcp-server 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 mcp-server 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

mcp-server 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 24d 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.

Who This Is For

  • AI agents: Automate repository tasks with minimal context
  • Contributors: Humans using AI assistants or working directly
  • Maintainers: Ensure assistants follow project conventions and CI rules

Agent Behavior Policy

AI agents should:

  • Make atomic, minimal, and reversible changes.
  • Prefer local analysis (uv run, make verify, make test-python) before proposing commits.
  • NEVER modify configuration, CI/CD, or release automation unless explicitly requested.
  • Avoid non-deterministic code or random seeds without fixtures.
  • Use AGENTS.md and Makefile as the source of truth for development commands.

Agents must NOT:

  • Bypass tests or linters
  • Introduce dependencies without updating pyproject.toml
  • Generate or commit large autogenerated files
  • Change MCP tool schemas, names, or required parameters without KEP / maintainer discussion

Context Awareness

Before writing code, agents should:

  • Read docstrings and existing test cases for pattern alignment
  • Match import patterns from neighboring files
  • Preserve existing logging, audit wrapping, and error-handling conventions

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.
