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 | $0.00369 |
| Opus 5 | $0.00016 | $0.00185 |
| Sonnet 5 | $0.00007 | $0.00074 |
| Haiku 4.5 | $0.00003 | $0.00037 |
Grade A, and why
connecting-apis-to-mcp 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 11d 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
connecting-apis-to-mcp
Connect a real API using managed credentials and mappings proven against observed output.
Use when
- Connect this OpenAPI URL to MCP.
- Use these API credentials for a real connector.
Do not use when
- Do not use for static local behavior.
- Do not use when credentials or a representative safe read are unavailable.
Required inputs
- API base URL and authentication scheme.
- Representative safe read.
- User intent and observed response shape.
Workflow
Read and follow the canonical playbook references/connect-an-api.md at ../noodle-seed/references/connect-an-api.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.
Verification evidence
A safe live read returns populated intentionally mapped fields through the effective local target.
Recovery paths
Separate authentication, transport, response-shape, mapping, and empty-result failures before editing.
Stop conditions
Stop before live writes without explicit approval, known effect, and a safe target.
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.

connecting-apis-to-mcp is a skill published in the GitHub repository Cyruskraad/codex-claude-mcp (0 stars, last pushed 15d ago), licensed MIT. It adds 33 tokens to every session and 369 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.
