Developer tools and APIs I build and run myself as Flovoice SRL, a small company in Romania. All of them are live in production. Most are for teams testing signup and verification flows, and for people building AI agents.
Real UK mobile numbers on physical SIM cards for SMS/OTP verification. One-time codes with automatic refunds, monthly rentals, a REST API, signed webhooks and an MCP server for AI agents.
Data eSIMs for the UK, Turkey, the US, Europe and Thailand, delivered by email. The UK bundle adds a UK number for WhatsApp, for people who need data and a number that receives SMS before they land.
A disposable email API for testing signup flows. Create an inbox with one request, no account, and read the verification email or the extracted code. Plugins for Playwright, Cypress and n8n.
Synthetic monitoring for verification codes. It rents a real number or inbox, you trigger your own OTP send to it, and it reports whether the SMS or email code actually arrived and how fast, with delivery rate and latency per channel.
An MCP server that gives an AI agent a disposable email address and a real UK phone number to test signup flows end to end. Runs locally from npm or hosted, with OAuth sign-in for Claude.
A mock store that implements the Agentic Commerce Protocol checkout API with real PayPal sandbox payments and a hosted MCP server, so an AI agent can shop and pay end to end without real money. Built for PayPal's AI agent hackathon.
A free, offline static scanner for MCP servers: SSRF in tool handlers, hardcoded secrets, command injection and poisoned tool descriptions. SARIF output for CI, plus a hosted scan history.
Usage metering for MCP servers: calls, latency and errors per tool and per client, in three lines of setup and with no dependencies.
A read-only MCP server for one Shopify store, so an AI agent can answer questions about orders, products and stock without being able to change anything.
