  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by RedHatProductSecurity on GitHub. Read the source before you install it.

Installation

Install the Oauth21 Implementation AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/RedHatProductSecurity/prodsec-skills/tree/main/module/skills/oauth21-implementation
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/RedHatProductSecurity/prodsec-skills.git /tmp/prodsec-skills
mkdir -p .claude/skills
cp -r /tmp/prodsec-skills/module/skills/oauth21-implementation .claude/skills/oauth21-implementation
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Oauth21 Implementation in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Oauth21 Implementation on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Oauth21 Implementation is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

OAuth 2.1 Implementation for Authorization Servers

Security Requirement

Authorization servers MUST implement OAuth 2.1 for both confidential and public clients. OAuth 2.1 consolidates security best practices from OAuth 2.0 and its extensions into a single specification.

Key OAuth 2.1 Requirements

RequirementDetails
PKCE requiredAll authorization code grants MUST use PKCE (RFC 7636), even for confidential clients
Redirect URI exact matchingRedirect URIs MUST be compared using exact string matching
No implicit grantThe implicit grant type is removed
No resource owner password grantThe ROPC grant type is removed
Refresh token rotationRefresh tokens MUST be sender-constrained or one-time use
Bearer token usagePer RFC 6750 with additional security requirements

Required Grants for MCP Ecosystem

The authorization server MUST support:

  • authorization_code + PKCE: For human users via MCP clients (public clients)
  • client_credentials: For service-to-service MCP communication (confidential clients)
  • device_code: For CLI tools and headless MCP clients
  • Token Exchange (RFC 8693): For MCP servers accessing downstream tools

Implementation Checklist

  • Implement OAuth 2.1 compliant authorization code flow with mandatory PKCE
  • Enforce exact redirect URI matching
  • Remove or disable implicit and ROPC grant types
  • Implement refresh token rotation (one-time use or sender-constrained)
  • Support client_credentials grant for confidential clients
  • Support device_code grant for CLI/headless clients
  • Implement Token Exchange (RFC 8693)
  • Issue short-lived access tokens (TTL ≤15min recommended)
  • Support resource indicators (RFC 8707) for multi-resource environments

Frequently asked questions

What does the Oauth21 Implementation AI skill do?

Enforce OAuth 2.1 implementation in authorization servers for MCP ecosystems. Use when building, configuring, or reviewing authorization servers that serve MCP clients and servers.

Why use Oauth21 Implementation on TypingMind?

Because you install it once and use it with any model. Oauth21 Implementation is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Oauth21 Implementation in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/RedHatProductSecurity/prodsec-skills/tree/main/module/skills/oauth21-implementation. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Oauth21 Implementation?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Oauth21 Implementation?

As many as you like. As long as a model supports skills, you can use Oauth21 Implementation with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Oauth21 Implementation AI skill free?

Yes. It is published on GitHub by RedHatProductSecurity under the Apache-2.0 license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
