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 | $0.00514 | $0.00514 |
| Opus 5.5 | $0.00206 | $0.00206 |
| Sonnet 5.5 | $0.00103 | $0.00103 |
| Haiku 4.5 | $0.00051 | $0.00051 |
Grade A, and why
x402-mcp-commerce 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 9d 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 — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Operating notes for AI coding agents (Claude Code, Codex, Cursor, Copilot and others) working in this repository. Everything here is derived from the files actually in the tree, so trust it over guesses, and update it when the facts change.
What this repository is
MCP server that gives Claude/GPT agents commerce tools - each tool call pays an upstream x402 endpoint and returns its artifact

Run the test and lint commands above before you consider a change finished. If a command fails on code you did not touch, say so in your report instead of silently skipping it.
Conventions
- TypeScript runs in strict mode; do not loosen
tsconfig.jsonto make an error go away. .envfiles are gitignored; never commit credentials, and read configuration from environment variables.- Commit messages follow Conventional Commits (
type(scope): summary), matching the existing history. - Read the surrounding code before adding to it, and match its naming, file organisation and error-handling style.
- Keep
README.mdaccurate: if a change alters behaviour, commands or configuration, update the docs in the same commit. - Do not leave TODO comments, stub functions, placeholder data or commented-out code behind. Finish what you start or leave it out.
- Small, focused commits with a subject line that describes the change, not the act of committing.
Where to raise things

- Questions and ideas: https://github.com/nirholas/x402-mcp-commerce/discussions

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.
