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 | $0.00176 | $0.04080 |
| Opus 5 | $0.00088 | $0.02040 |
| Sonnet 5 | $0.00035 | $0.00816 |
| Haiku 4.5 | $0.00018 | $0.00408 |
Grade A, and why
frontmcp-production-readiness 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 Production Readiness Audit
Router for production readiness checklists. Start with the common checklist (security, performance, reliability, observability), then follow the target-specific checklist for your deployment environment.
When to Use This Skill
Must Use
- Before deploying a FrontMCP server to production for the first time
- After major feature additions or architectural changes
- During security reviews or compliance audits
Recommended
- As part of PR reviews for infrastructure-touching changes
- Quarterly health checks on production deployments
- When switching deployment targets
Skip When
- Building a prototype or proof-of-concept
- Running in development/local mode only
Decision: Use this skill when preparing for production. Start with
common-checklist, then pick your deployment target.
Prerequisites
- A deployable FrontMCP project (build target chosen, see
frontmcp-deployment). - Observability and structured logging available (see
frontmcp-observability) — production hardening assumes you can see what the server is doing. - A staging environment matching production target (Node, Vercel, Lambda, Cloudflare, CLI, browser) to validate the checklist before go-live.
Steps
Step 1: Detect Deployment Target
Check the project to determine the deployment target:
- Look at
package.jsonscripts forfrontmcp build --target <target> - Check for target-specific files:
ci/Dockerfile(node),vercel.json(vercel),wrangler.toml(cloudflare),ci/template.yaml(lambda) - Check if the build target is
cliorbrowserin the build config - If unclear, ask the user which environment they're deploying to
Step 2: Run Common Checklist
Always start with the common checklist — it covers security, performance, reliability, and observability that apply to every target.
Step 3: Run Target-Specific Checklist
After the common checklist, run the checklist for your deployment target.

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-production-readiness is a skill published in the GitHub repository agentfront/frontmcp (146 stars, last pushed 7d ago), licensed Apache-2.0. It adds 176 tokens to every session and 4,080 once invoked, about $0.0009 per session on Opus 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.
