mcp-power-automate: Instructions file for Codex

AGENTS.md

mcp-power-automate AGENTS.md is an instructions file for Codex, OpenCode from kaael1/mcp-power-automate. It costs 496 tokens per session, scanned A, original, MIT.

Repository instructions for a local Model Context Protocol (MCP) server, browser extension, and Codex skill that operate Microsoft Power Automate flows. Power Automate is Microsoft’s service for building automated workflows between apps and services.

In plain words
What is it for?
Checking flow status, inspecting flows, making supervised changes, testing before and after saving, and maintaining the local MCP server and browser extension.
Why use it?
They require flow changes to be inspected, validated, observable, and easy to undo, especially before touching production workflows. They also keep the server, browser extension, and skill consistent with one another.

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

This is kaael1/mcp-power-automate's own configuration. It tells Codex and OpenCode how to work on mcp-power-automate 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-power-automate 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-power-automate 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 10d 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 — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

This repository contains a local MCP server, a Chromium extension, and a Codex skill for operating Power Automate flows.

Goals

  • Keep the MCP and the skill aligned
  • Prefer safe, supervised automation over opaque convenience
  • Make flow changes observable, reversible, and testable

Working rules

  1. Do not make destructive flow changes by default.
  2. Prefer editing test or staging flows before production flows.
  3. Before changing a flow, inspect it with get_status and get_flow.
  4. Validate before and after save when possible.
  5. Keep changes minimal and easy to revert.
  6. Preserve the browser-backed workflow: the extension provides the live target flow and session context.
  7. When changing the server, keep the popup and skill instructions in sync.
  8. Runtime-generated files in data/ are local state and must not be committed.

Repository map

  • server/: MCP server, HTTP bridge, local persistence
  • extension/: browser extension for capture, status, and light controls
  • skills/power-automate-mcp/: reusable skill instructions for Codex
  • data/: runtime state only

Local Codex registration

When working from this checkout, prefer registering Codex against the local built server instead of the published npx package so local fixes are exercised:

npm run build
$nodePath = (Get-Command node).Source
$serverPath = Join-Path (Get-Location) "dist/server/index.js"
codex mcp add power-automate-local -- $nodePath $serverPath

If an older power-automate-local entry already exists, remove it first with:

codex mcp remove power-automate-local

Load the browser extension from dist/extension after rebuilding. If the popup says the bridge is offline while http://127.0.0.1:17373/health works, check for a version mismatch between the extension bundle and the running bridge.

Publishing guidance

  • Keep the skill in this same repository unless there is a strong reason to split release cycles.
  • If you add or rename MCP tools, update:
    • skills/power-automate-mcp/SKILL.md
    • README.md
    • popup wording if user-facing behavior 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.
