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 | $0.01106 | $0.01106 |
| Opus 5.5 | $0.00442 | $0.00442 |
| Sonnet 5.5 | $0.00221 | $0.00221 |
| Haiku 4.5 | $0.00111 | $0.00111 |
Grade A, and why
agentic-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 3d 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 — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Gotchas
pnpm run— alwayspnpm run <script>, never barepnpm <script>.- No extensions on relative imports — use
'./foo', never'./foo.ts'or'./foo.js'. Package imports use the specifier the package exports, extension included only when the export has one ('@modelcontextprotocol/server/stdio'). - Config over code — new providers go in
providers.json, not in source files. No code changes, no rebuilds. - Never
shell: true— all spawns usecross-spawnwith array args. Never pass user input through a shell.
Architecture
- Multi-model AI gateway wrapping CLI tools as MCP servers: Claude, Codex, Copilot, Gemini, OpenCode (stable) and Antigravity
agy(beta), plus the other beta/community CLIs and disabled templates inproviders.json - Config-driven: providers defined in
src/config/providers.jsonwith Zod-validated schema (providers.schema.json) - Entry point:
src/index.ts->src/entry/domain-logic/entry.ts(handles --version, --help, setup subcommand, or starts MCP server)

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.
