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 | $0.02969 | $0.02969 |
| Opus 5.5 | $0.01188 | $0.01188 |
| Sonnet 5.5 | $0.00594 | $0.00594 |
| Haiku 4.5 | $0.00297 | $0.00297 |
Grade A, and why
btp-cf-mcp AGENTS.md 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Guidance for AI coding agents working in this repo. Single source of truth — CLAUDE.md imports it.
Keep it terse: task → files + ≤1 gotcha per row. Deep detail lives in docs/ (read on demand).

Project Overview
btp-cf-mcp is a TypeScript MCP (Model Context Protocol) server for SAP BTP + Cloud Foundry management,
deployed on BTP Cloud Foundry, running IAS-first per-user auth. Tool surface (ADR-016/S3): reads and writes are
SEPARATE tools — CFInspect / BTPInspect (reads, readOnlyHint:true) + CFApps / BTPServices
(writes, blast-radius-grouped, hidden by default, not-yet-implemented). It reuses @arc-mcp/xsuaa-auth patterns
and the arc-1 scope/safety model.
Status & DECIDED direction — read the plan before touching auth or tools. The code below is the as-built PoC plus partial IAS/per-user spike code. Decided 2026-06-30: move to IAS-first inbound where the server issues its own MCP token and holds the IAS credential sealed (ADR-009/017); per-user CF and BTP (BTP via the CLI Server, ADR-004; CIS demoted to fallback, ADR-003); and a ≤12 resource-split
CF*/BTP*tool surface with reads separated from writes (ADR-016). Build toward the plan, not toward the current PoC shape.
Design Principles
- Read-only by default, opt-in power —
ALLOW_WRITES=false; every mutation refused until enabled + target allowlisted. - Two authz layers — the MCP scope gate (
read/write/admin) is defense-in-depth + LLM-surface control; the real authz is the user's BTP/CF roles (per-user) or the technical identity's (shared). - Fail closed — no auth method configured ⇒ refuse to start (unless
ALLOW_OPEN); per-user scopes only narrow the server ceiling. - Call the REST APIs the CLIs use — not the CLI binaries (Cloud Controller API + CIS REST), unless
cf push/exotic commands force it. - Per-credential scope — one CIS key / one CF identity = one subaccount/GA; no roaming.
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.

btp-cf-mcp AGENTS.md is an instructions file published in the GitHub repository marianfoo/btp-cf-mcp (2 stars, last pushed 3d ago), licensed MIT. It adds 2,969 tokens to every session, about $0.0119 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 2026-08-31.
