What is mcp-newebpay CLAUDE.md?

Project instructions for mcp-newebpay, a server that lets AI call six NewebPay payment APIs through a standard tool interface. NewebPay, also called 藍新金流, is a payment service; the instructions cover setup, running, testing, and the code structure.

Use them when setting up, running, testing, or changing the mcp-newebpay server and its payment operations, such as querying, cancelling, closing, or refunding payments.

They give a coding agent the project’s required commands, architecture, authentication details, and implementation patterns in one place.

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	$0.00461	$0.00461
Opus 5	$0.00230	$0.00230
Sonnet 5	$0.00092	$0.00092
Haiku 4.5	$0.00046	$0.00046

Measured 9d ago against content hash a96118661875, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-09, from the pricing page.

Security

Grade A, and why

mcp-newebpay 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 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.

What it actually says

MCP NewebPay

Overview

MCP Server for NewebPay (藍新金流) that exposes 6 backend payment APIs as AI-callable tools over stdio JSON-RPC 2.0. Part of the Asgard open-source ecosystem.

Setup

uv venv && source .venv/bin/activate
uv pip install -e .

Run

python mcp_server.py

Test

python scripts/auth/test_connection.py
python tests/test_all_tools.py

Architecture

stdio (JSON-RPC 2.0)
  → mcp_server.py (entry point, side-effect imports trigger tool registration)
    → app.py (MCPServer singleton)
      → tools/payment_tools.py    (NDNF: query, cancel, close/refund, e-wallet refund)
      → tools/periodic_tools.py   (NDNP: alter status, alter content)
        → connectors/newebpay_client.py (AES encrypt/decrypt + Form POST)
          → auth/newebpay.py            (Merchant ID + Hash Key/IV)
            → config/settings.py        (endpoints, URL builder)

Key Patterns

Singleton: app.py creates the MCPServer instance, imported everywhere
Decorator registration: @mcp.tool() with Pydantic Field() for typed parameters
Side-effect imports: mcp_server.py imports tool modules to trigger registration
AES encryption: All NewebPay APIs require AES-256-CBC encrypted payloads
Environment switch: NEWEBPAY_ENV=test|production toggles sandbox vs live

API Coverage

NDNF (Online Transaction): Trade Query, Cancel Auth, Close/Refund, E-wallet Refund
NDNP (Recurring Payment): Alter Status, Alter Content

Code Conventions

English for all code, docstrings, and tool descriptions
Use newebpay_post() from connector — don't call requests directly in tools
All tools return dict
Use Pydantic Field() for parameter descriptions and defaults

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.
