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 | $0.01281 | $0.01281 |
| Opus 5.5 | $0.00512 | $0.00512 |
| Sonnet 5.5 | $0.00256 | $0.00256 |
| Haiku 4.5 | $0.00128 | $0.00128 |
Grade A, and why
aiden-mcp CLAUDE.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 2mo 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 — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.
aiden-mcp — project map
Unofficial MCP server for the Fellow Aiden coffee brewer. Lets Claude push/list/delete/share brew profiles on the Aiden over Fellow's private API, scrape coffee details from roaster product pages, and apply Aiden-specific brewing heuristics to design a recipe. TypeScript, runs as a Cloudflare Worker (Streamable-HTTP MCP transport + OAuth 2.0). Pairs with the Fellow_Aiden MCP connector; vault notes live at 05) maker/aiden-mcp.

Where things live
- Machine: 🐧 dev/build on ravelab. Deploys to Cloudflare Workers (
npx wrangler deploy) — live athttps://aidenmcp.ravenhoward.org/mcp. There is no long-running local server; the Worker is the runtime. - State: none persistent. Cloudflare KV (
AIDEN_OAUTH) holds only short-lived records — auth codes ≤10min, access tokens ≤1hr, client regs ≤90d. Only Fellow-issued JWTs are stored, never the Fellow password. - Secrets: Cloudflare Worker secrets (
npx wrangler secret put …) — canary account creds + webhook. Local dev vars in.dev.vars(untracked). Never in-repo. - Auth model: OAuth 2.0 auth-code + PKCE, or
X-Fellow-Email/X-Fellow-Passwordheaders. Password reaches server once at/oauth/authorize, exchanged for a Fellow JWT, then discarded. - Profile data (temperature/ratio priors) is harvested, not folk wisdom — see
data/.

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.
