Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 11 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00157 | $0.05172 |
| Opus 5.5 | $0.00063 | $0.02069 |
| Sonnet 5.5 | $0.00031 | $0.01034 |
| Haiku 4.5 | $0.00016 | $0.00517 |
Grade A, and why
frontmcp-guides 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 9d 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.

FrontMCP End-to-End Guides
Complete build walkthroughs and best practices for FrontMCP servers. Each example starts from an empty directory and ends with a deployed, tested server. Every pattern references the specific skill that teaches it.
When to Use This Skill
Must Use
- Starting a new FrontMCP project from scratch and want a complete walkthrough to follow
- Learning FrontMCP architecture by building progressively complex real examples
- Need to see how multiple skills work together in a complete application
Recommended
- Planning a new project and want to see how similar architectures are structured
- Onboarding a team member who learns best from complete working examples
- Reviewing best practices for file organization, naming, and code patterns
Skip When
- You need to learn one specific component type (use the specific reference, e.g.,
create-toolunderfrontmcp-development/references/) - Looking for the right reference for a task (use domain routers:
frontmcp-development,frontmcp-deployment, etc.) - You need CLI/install instructions for the skills system (see
frontmcp-skills-usage)
Decision: Use this skill when you want to see how everything fits together. Open individual references under each router's
references/directory when you need focused instruction.
Prerequisites
- Node.js 24+ and npm/yarn installed
- Familiarity with TypeScript and decorators
frontmcpCLI available globally (npm install -g frontmcp)
Steps
- Choose an example that matches your project's complexity level (Beginner, Intermediate, Advanced)
- Work through the Planning Checklist to define your project's scope
- Follow the example code and architecture, referencing individual skills for deeper guidance
- Verify your implementation using the Verification Checklist at the end of this skill
Planning Checklist
Before writing any code, answer these questions:
1. What does the server do?
- What tools does it expose? (actions AI clients can call)
- What resources does it expose? (data AI clients can read)
- What prompts does it expose? (conversation templates)
What ships with it
12 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

frontmcp-guides is a skill published in the GitHub repository agentfront/frontmcp (146 stars, last pushed today), licensed Apache-2.0. It adds 157 tokens to every session and 5,172 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
