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 | $0.00033 | $0.00408 |
| Opus 5 | $0.00016 | $0.00204 |
| Sonnet 5 | $0.00007 | $0.00082 |
| Haiku 4.5 | $0.00003 | $0.00041 |
Grade A, and why
authoring-mcp-servers 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.
What it actually says
authoring-mcp-servers
Deliver focused model-facing MCP behavior through the configured TypeScript entrypoint.
Use when
- Build a headless MCP server.
- Add a typed tool, resource, or prompt.
Do not use when
- Do not use when the primary outcome is a widget.
- Do not use only to diagnose or deploy existing behavior.
Required inputs
- Requested user intent.
- Expected typed result.
- External operation contract when applicable.
Workflow
Read and follow the canonical playbook references/build-an-mcp-server.md at ../noodle-seed/references/build-an-mcp-server.md. It owns the workflow; do not recreate it here or load the command catalog speculatively.
Load references/authoring-workflow.md at ../noodle-seed/references/authoring-workflow.md only when the playbook or observed evidence names that concern.
Load references/sdk-surface.md at ../noodle-seed/references/sdk-surface.md only when the playbook or observed evidence names that concern.
Verification evidence
The TypeScript behavior validates and passes local smoke; connector reads also have real-output proof.
Recovery paths
Resume at the first failing compile, smoke, credential, mapping, or live-read layer.
Stop conditions
Stop at local delivery unless another requested outcome explicitly authorizes a handoff.
Handoff contract
Pass the selected outcome, explicit target, changed files, commands run, passing evidence, first unproven evidence layer, sanitized failure, remaining authority, and exact next action. The receiving skill continues from that layer; do not restart discovery or discard prior proof.
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.

authoring-mcp-servers is a skill published in the GitHub repository Cyruskraad/codex-claude-mcp (0 stars, last pushed 14d ago), licensed MIT. It adds 33 tokens to every session and 408 once invoked, about $0.0002 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 2026-08-31.
