Description
Let your agent shop online with guardrailed wallets, multiple payment methods, and owner approval.
Usage Guidance
Key things to check before installing:
- Confirm the publisher and domain: the skill's files point to creditclaw.com but the registry name/slug mention 'MasterCard' — verify this mismatch with the publisher or registry metadata.
- Treat downloaded files as code: the flow requires saving files and executing a decrypt.js delivered with encrypted card files. Only run such scripts in a sandboxed environment and inspect the script contents before execution.
- Prefer the sub-agent flow: the docs recommend spawning an ephemeral sub-agent so the main agent never sees decrypted card details. If your agent platform cannot isolate sub-agents, avoid enabling this skill or avoid using rail5/encrypted-card functionality.
- Limit the API key: give the skill a dedicated CREDITCLAW_API_KEY with least privilege and monitor usage. Do not reuse a high-privilege or multi-service key.
- Review guardrails: ensure approval_mode and per-transaction/daily limits are strict (ask_for_everything or low thresholds) before permitting autonomous purchases.
- If you are unsure about the domain or publisher identity, do not install. Request clarification from the registry owner/maintainer or use a vetted alternative.
Capability Analysis
Type: OpenClaw Skill
Name: mastercard
Version: 1.0.2
The bundle describes a financial enablement platform for AI agents to manage spending and payments via encrypted cards and USDC. It features robust security protocols, such as server-side enforcement of spending limits, single-use decryption keys, and the use of ephemeral sub-agents to isolate sensitive information. The instructions in SKILL.md and ENCRYPTED-CARD.md are transparent about security risks and provide clear guidance on protecting API keys, with no evidence of malicious intent or unauthorized data exfiltration (IOC: creditclaw.com).
Capability Assessment
Purpose & Capability
The skill's files and SKILL.md implement a 'CreditClaw' shopping/checkout integration and correctly require a CREDITCLAW_API_KEY. However the registry-level name/title provided ('MasterCard | Is your claw a shopaholic?') and slug 'mastercard' do not match the content (creditclaw.com, creditclaw-creditcard). This mismatch could be a benign metadata error, but it is an incoherence that deserves verification from the publisher.
Instruction Scope
The runtime instructions direct the agent to: fetch multiple files via curl from https://creditclaw.com, save them under ~/.creditclaw, handle webhooks/messages that deliver encrypted card files, and (critically) run a delivered decrypt.js script (node decrypt.js ...) inside an ephemeral sub-agent or, as an alternative, directly in the main agent. Downloading and executing code delivered at runtime broadens scope beyond simple API calls and can expose decrypted card data to the agent if sub-agents aren't used.
Install Mechanism
There is no formal install spec (instruction-only), but SKILL.md explicitly provides curl commands to download and store multiple skill files. While fetching files from the service domain is expected for this use-case, it results in persistent files on disk and the skill's flow requires executing a decrypt script embedded in a delivered file — a higher-risk pattern than pure instruction-only skills that only call remote APIs.
Credentials
The skill requires a single credential CREDITCLAW_API_KEY and uses it exclusively in examples and endpoints under creditclaw.com/api/v1. The requested env var is proportionate to the payment/checkout functionality described. No unrelated secrets or broad environment access are declared.
Persistence & Privilege
The skill does not request 'always' or elevated platform privileges, but its instructions direct saving files under ~/.creditclaw and .creditclaw/cards and instruct spawning ephemeral sub-agents. This creates persistent artifacts and runtime execution (decrypt.js). That persistence/execution is reasonable for encrypted-card workflows but increases blast radius if the domain or delivered scripts are untrusted.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install mastercard - After installation, invoke the skill by name or use
/mastercard - Provide required inputs per the skill's parameter spec and get structured output
