What is 402-mcp AGENTS.md?

Project instructions for AI coding agents working on the 402-mcp codebase. AGENTS.md is a file that tells coding tools how a project is built, tested, structured, and written.

It helps agents build the project, run Vitest tests, check TypeScript types, follow its file structure and coding conventions, and apply its security patterns.

It gives an agent the project rules and commands it needs to make changes that fit the existing codebase.

Token cost

What it costs to keep this loaded

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	$0.02277	$0.02277
Opus 5.5	$0.00911	$0.00911
Sonnet 5.5	$0.00455	$0.00455

Security

Grade A, and why

402-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 18d 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.

AGENTS.md - 402-mcp

L402 client MCP: AI agents discover, pay for, and consume Lightning and ecash payment-gated APIs within human-set limits. x402 support is experimental and uses a custom format, not the x402 specification.

Commands

npm run build       # tsc -> build/
npm test            # vitest run
npm run typecheck   # tsc --noEmit
npm run lint        # eslint src/

Running

# Stdio transport (default - used by MCP clients like Claude Desktop)
node build/index.js

# HTTP transport (needs a bearer token file; stateless, one server per request)
TRANSPORT=http HTTP_AUTH_TOKEN_FILE=~/.402-mcp/http.token PORT=3402 node build/index.js

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.
