Professional tools to take VFP applications to HTTP, .NET, parallel processing, automation and AI agents.
This site and its API run on FoxServer. In production, right now.Pick what you want to achieve and start with the product that does it.
I want to take a Visual FoxPro application I already have to HTTP, APIs, .NET, parallel processing or Windows services without rewriting it.
I want Claude or other agents to understand, inspect or work with a VFP application while it is running.
I want to turn VFP logic I already have into commands that both users and AI agents can run.
I want Claude or another agent to work with my VFP code, tests, tables and libraries from a single MCP entry. Free.
I want a technician to work with Claude on a remote Windows machine without AnyDesk. The agent is copied to that machine and shuts itself down when nobody is using it.
I want to add AI and automation to the product I ship to my own customers.
Each product opens a different door in your VFP application, and you can add them one at a time.
Each tool is independent. Buy only what you need: the ones in the last group are free.
REST API for Visual FoxPro · Run VFP in the background · Use .NET from Visual FoxPro · Windows service with Visual FoxPro
HTTP server for Visual FoxPro
Integrate your VFP applications with the modern world. REST API, webhooks, JWT, middleware: all from VFP without IIS or Apache.
Deployment license
FoxServer Runtime
FoxServer licenses are for development and only answer requests from the same machine (127.0.0.1). To put your application on a server that other machines call, each server needs a FoxServer Runtime license; a software house that ships its application covers all its customers with a single one, the ISV license.
See FoxServer Runtime →Parallel processing for VFP
Run tasks in the background without blocking your UI. Real concurrency and async for your VFP applications.
.NET bridge for Visual FoxPro
Use any .NET library directly from VFP. List<T>, Dictionary, HttpClient, async/await and more, without leaving your Fox environment.
Windows services written in VFP
Your VFP logic, as a Windows service: jobs at a time of day, every so often or when a file arrives, without a PC with the program open. It starts with the computer and comes back up by itself if it falls.
AI for Visual FoxPro applications
Connect Claude to your Visual FoxPro applications
MCP bridge between Claude Desktop and any running VFP instance. Real-time inspection, diagnostic tools and custom UDTs so AI can understand and operate your legacy application.
License for software vendors
FoxAgent Runtime (ISV)
FoxAgent Runtime (ISV) is the license a software house uses to ship FoxAgent alongside its application: one per company, for all its customers. If you only develop with FoxAgent on your own machine, the Developer license is the one you need.
See FoxAgent Runtime (ISV) →Turn VFP code into a CLI · MCP tools for VFP
Console applications written in VFP
Your VFP methods, turned into a console .exe with its help, typed options, exit codes and JSON output. It ships by copying a folder.
Your VFP CLI, as tools for an AI agent
The MCP server of every CLI you build with FoxCli: Claude discovers your commands and calls them, with no new code from you. The logic runs on the agent's machine.
The two licenses, 20 % less
FoxCli and the MCP server of its CLIs in one purchase: two licenses, per programmer, 20 % cheaper than separately.
Remote access for software technicians
Claude on your customer's machine, without AnyDesk
Eyes and hands for Claude on another Windows machine, over MCP. The agent is copied onto the remote machine, is free and shuts itself down; what is licensed is the technician's client.
SQL for Claude on your customer's database, with a safety net
An add-on for Golem that lets Claude run whatever SQL is needed on a customer's database. Every change is previewed, what was there is kept and can be restored, and everything goes into an audit log.
One MCP server for your VFP tools · Library manager for VFP
Your VFP tools, for an agent, through a single MCP entry
A local MCP server that brings together the tools you install (FoxKit, FoxPack, FoxCli, FoxServer). Claude sees one server with the tools of all of them.
Three console tools for VFP
vfp2text, foxproof and foxengine: binaries to text, tests and DBF tables from the console, without Visual FoxPro installed. They work on their own and, with FoxStack, from an agent too.
VFP libraries at a fixed version
Downloads VFP libraries from GitHub with the version, the commit and the SHA-256 written down in foxpack.lock. Whoever clones your project gets the same versions.
The site you are visiting and its API run on FoxServer, in production. The page, the API and its endpoints are served by the same process: a Visual FoxPro 9 MTDLL listening for HTTP on a Windows VPS.
No credit card. Verify your email and you get 30 days of a full license (not a cut-down build) for FoxServer, FoxCore, FoxBridge, FoxAgent, FoxCli and FoxCli MCP, installer included, in your portal. One per person and product; after 30 days it expires.
Any license in the catalog, with the discount applied at checkout. No codes.

Software engineer specialized in developer tooling for the FoxPro and .NET ecosystem.
I have been working with Visual FoxPro for more than 17 years, and I build tools that let you extend VFP applications into .NET, HTTP, automation and AI agents without having to rewrite them.
Software Engineer · Tool Developer · AI Integration Specialist
Over 17 years of experience in Visual FoxPro with a specialized focus on infrastructure and tooling for developers: frameworks, runtimes, libraries and SDKs that extend the FoxPro ecosystem into the modern world. Member of the X# language DevTeam, international speaker and creator of FoxServer, FoxAgent, FoxCore, FoxBridge and Golem.
Perpetual licenses, one-time payment. The tool works forever, with every version published up to the end of your maintenance.
Each seat covers one developer; FoxAgent is licensed per development machine, FoxCore is one license per company with no seat counting, and Golem goes per technician (bound to their machine) or per team (company license, not bound to a machine). Choose the pack that best fits your team.
Tutorials, use cases and news from the FoxPro and X# ecosystem.
On disconnect, the Guardian frees the slot at once. If it is taken, whoever arrives sees who has it, can leave them a note and wait for their turn, and if the holder has forgotten the session, it is handed over after 5 minutes.
