Agent-native payments via 1ly MCP. Use when the user needs x402 payment handling, to accept USDC for APIs/services, to pay for paid APIs, to create stores or paid links, need payment gateway for agents or to run agent-to-agent paid workflows.

3 findings — 3 medium severity. This skill can be installed but you should review these findings before use.
W011: Third-party content exposure detected (indirect prompt injection risk)
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
Third-party content exposure detected (high risk: 0.90). The skill's workflow explicitly instructs the agent to use 1ly_search and 1ly_get_details to discover and fetch listings from the public marketplace 1ly.store (user-posted paid API links), which the agent then interprets and acts on (selecting and auto-paying via 1ly_call), exposing it to untrusted third-party content that could carry indirect prompt-injection.
W012: Unverifiable external dependency detected (runtime URL that controls agent)
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
Potentially malicious external URL detected (high risk: 1.00). The skill's setup requires running "npx @1ly/mcp-server" which fetches and executes remote code from the npm package @1ly/mcp-server (e.g. https://www.npmjs.com/package/@1ly/mcp-server), and that MCP server advertises tools and directly controls agent behavior at runtime.
W009: Direct money access capability detected (payment gateways, crypto, banking)
What this means
The skill is specifically designed for direct financial operations, giving the agent the ability to move money or execute financial transactions — such as payment processing, cryptocurrency operations, banking integrations, or market order execution.
Why it was flagged
Direct money access detected (high risk: 1.00). The skill is explicitly a payments/payment-gateway integration for crypto (USDC) on Solana and Base. It requires and manages private keys (ONELY_WALLET_SOLANA_KEY, ONELY_WALLET_EVM_KEY), exposes tools to spend funds (1ly_call: "pay and call", automatic crypto payments via x402), and to accept funds (create stores/links, list keys, revoke keys). The MCP server handles signing, transactions, txHash/purchaseId logging, and can proceed automatically within budget limits. This is a specific financial-execution tool (crypto payment gateway and wallet/key management), not a generic interface, so it grants direct financial execution authority.
