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 | $0.00502 | $0.00502 |
| Opus 5.5 | $0.00201 | $0.00201 |
| Sonnet 5.5 | $0.00100 | $0.00100 |
| Haiku 4.5 | $0.00050 | $0.00050 |
Grade A, and why
authsome-mcp-proxy 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 15d 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 — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
authsome-mcp-proxy is a public, Apache-2.0-licensed open-source project.
Everything committed here — code, comments, docstrings, tests, docs,
examples, Dockerfiles, CI workflows, commit messages and PR descriptions — is
published to the world.
No proprietary references
Never put references to proprietary material into this repository. That covers anything belonging to the maintainers' employers, customers or other non-public projects:
- product, project, team or codename names of commercial or internal offerings (including in display-name examples, fixture values and test server names);
- company-specific hostnames, domains, URLs, tenant/user-pool/account IDs, ARNs, cluster or namespace names;
- internal issue trackers, repositories, merge requests, wikis, chat channels, meeting decisions or people who are not public contributors;
- deployment details of a specific non-public installation ("the X deployment uses …", "in front of X / Y").
Use neutral placeholders instead:
| Kind | Use |
|---|---|
| Product / server name | Acme Analytics, acme-repository-mcp, upstream-mcp |
| Domains and URLs | example.com / .org / .net (RFC 2606), auth.company.com, mcp-upstream.company.com |
| Cloud IDs | obviously fake values such as eu-central-1_XXXXXXXXX, eu-central-1_abc, tid |
| Deployment context | generic wording: "a production deployment", "token-validating upstream MCP servers" |
Public third-party services and standards (Cognito, Keycloak, Azure, Google, GitHub, GitLab, Personio, Lexware, CoinDesk, RFCs, the MCP SDK and FastMCP issue numbers) are fine to name.
Before finishing any change, check the diff for names, hosts or IDs that come from a non-public context and replace them. When in doubt, use a placeholder. A commit or PR that removes such a reference describes the change generically ("use neutral placeholder names") and never quotes or names what was removed, nor points at the earlier commits that introduced it.
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.
