What is x402-mcp-stellar AGENTS.md?

Repository instructions for an MCP server that connects x402 payments with Stellar, a blockchain network. They describe the TypeScript source layout, development commands, code style, and testing expectations.

Use them when adding or changing server tools, payment protocol logic, Stellar modules, configuration, or TypeScript code in this repository.

They show an agent where Stellar payment code belongs and how to build and run the server consistently.

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	$0.00538	$0.00538
Opus 5	$0.00269	$0.00269
Sonnet 5	$0.00108	$0.00108
Haiku 4.5	$0.00054	$0.00054

Security

Grade A, and why

x402-mcp-stellar 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 8d 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.

Repository Guidelines

Project Structure & Module Organization

src/index.ts: MCP stdio server entrypoint, tool registration, env loading, and x402 payment wiring.
src/stellar/: vendored Stellar payment implementation (signer, constants, shared types, utilities).
src/stellar/exact/{client,server,facilitator}/: exact scheme protocol logic and adapters.
Root config/files: package.json, tsconfig.json, .env.example, README.md.
Keep new features in src/; place Stellar-specific logic alongside existing src/stellar/* modules.

Build, Test, and Development Commands

npm install: install dependencies (requires Node.js 20+).
npm run dev: run the MCP server with tsx for local development.
npm run start: run the server in a production-like mode with source maps.
npm run build: TypeScript type-check only (tsc --noEmit); run this before opening a PR.

Coding Style & Naming Conventions

Language: TypeScript (ES modules) with strict compiler settings.
Formatting in current codebase: 2-space indentation, semicolons, double quotes.
File/module naming: lowercase, descriptive names (for example signer.ts, constants.ts).
Prefer explicit, descriptive function names (for example getRequiredEnv, tryParseBody) and clear types on exported APIs.

Testing Guidelines

No dedicated test runner is configured yet; npm run build is the minimum validation gate.
For behavior changes, include manual verification steps:
1. Copy .env.example to .env and set wallet values.
2. Start facilitator and x402-protected resource server.
3. Run npm run dev and exercise fetch_paid_resource.
If you add tests, use *.test.ts naming and colocate with modules or under src/__tests__/.

Commit & Pull Request Guidelines

Use concise, imperative commit subjects, consistent with history (for example resource agnostic, Update README.md).
Keep commit subjects focused and under ~72 characters.
PRs should include: purpose, key changes, config/env impact, and verification commands/results.
Link related issues and include request/response examples when MCP tool behavior changes.

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.
