Generates a random account number.
AI agents call finance-accountNumber to retrieve information from Faker MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool generates fake/random data using Faker.js. It does not retrieve real data, modify anything, or perform financial transactions. It simply produces synthetic account number strings for testing purposes. No real-world side effects.
