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 Hardening Remote AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

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.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/RedHatProductSecurity/prodsec-skills/tree/main/module/skills/hardening-remote
Enable the skill in any chat where you want it available.

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/hardening-remote .claude/skills/hardening-remote

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Hardening Remote 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 Hardening Remote 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 Hardening Remote 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.

Hardening Remote MCP Servers

Security Requirements

MCP servers deployed as remote services require additional hardening to protect client connections and restrict network access.

TLS Everywhere

All client connections to the remote MCP server MUST use TLS:

Requirement	Details
TLS mandatory	Reject all plaintext (non-TLS) connections
TLS 1.2 minimum	TLS 1.3 preferred
Valid certificates	Use certificates from a trusted CA; do not use self-signed certs in production
Strong cipher suites	Disable weak ciphers and protocols
HSTS	If HTTP-based, set Strict-Transport-Security header

Network Segmentation

Control	Details
Firewalls	Restrict inbound traffic to only required ports from known sources
NetworkPolicies	In Kubernetes, use NetworkPolicies to control pod-level ingress and egress
Private networks	Place MCP servers in private subnets; use load balancers for public access
Segmentation	Isolate MCP servers from unrelated workloads

Cryptographic Server Verification

Clients MUST be able to verify the MCP server's identity:

Use valid TLS certificates issued by trusted Certificate Authorities
Support certificate pinning for high-security environments
Rotate certificates before expiry

Implementation Checklist

Enforce TLS on all client connections; reject plaintext
Use TLS 1.2 minimum, prefer TLS 1.3
Use certificates from a trusted CA (not self-signed)
Disable weak cipher suites and protocols
Implement firewall rules to restrict inbound traffic to required ports
Use Kubernetes NetworkPolicies for pod-level network control
Place MCP servers in private network segments
Rotate TLS certificates before expiry
Monitor for certificate expiration and configuration drift

Frequently asked questions

What does the Hardening Remote AI skill do?

Harden remotely deployed MCP servers with TLS, network segmentation, and server verification. Use when deploying, configuring, or reviewing MCP servers running as remote services.

Why use Hardening Remote on TypingMind?

Because you install it once and use it with any model. Hardening Remote 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 Hardening Remote in TypingMind?

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

Which AI models can use Hardening Remote?

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 Hardening Remote?

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

Is the Hardening Remote 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.
