On Friday, May 24, 2002, at 9:27 in the morning, Gus sent me an email with the subject line “Horse betting site.” Gus was one of the people behind a horse racing venture with Joe Russell, and the email named the data source the group wanted, brisnet.com, then walked me through six numbered steps to reach it. You clicked the free SuperTote link and went in as a guest, since nobody had a subscription yet, then picked a track from the first drop-down. “Hollywood Park is a good example,” he wrote. The track closed in 2013. SoFi Stadium sits on the site now. Three more clicks, through a framed page of green grids, and the exacta payoffs appeared in the bottom frame. He closed by asking for a URL I’d read to him over the phone, because it hadn’t worked.
I still have that email. Twenty-four years of mail migrations have not been kind to it. Quoted-printable encoding wraps long lines with an equals sign, and somewhere between EarthLink and today’s Outlook the equals signs survived and the letters next to them didn’t, so step one now tells you to click on FREE =uperTote. Outlook offers to summarize it with Copilot.
Four weeks later, on June 21, Gus followed up. “The partner who has the formulas for processing the horse race data will be in L.A. this weekend,” he wrote. That partner would meet with Joe, and one or both of them would tell me what needed to be done. That’s the paper trail. Joe’s version was better. A Russian mathematician had developed a secret exacta formula, and it was flying into the United States inside a laptop, carried by a courier.
My job was to write the program that scraped the exacta grid off that page and calculated the odds in real time. I was in the country illegally back then. I rented a room with a couch and a desk in Bob Glass’s house, and I worked for Jason Stavitsky at Web Business Development in Chatsworth for twenty dollars a day. Twenty dollars a day doesn’t buy a computer. I wrote it on Bob’s.
The standard line now is that nobody has to scrape anymore. There are APIs, there’s MCP, and an agent just asks a server for clean JSON. That line is half true, and the missing half is what killed my scraper. The Model Context Protocol standardized how a model asks for data. It didn’t change who decides whether to answer.
Gal Meets Bob. Gal Rents a Room at Bob’s
Bob was a card counter, and by the time I met him he had been barred from every casino. In Atlantic City, a casino told him to leave for counting. Bob went up to his room and went to sleep. The police woke him in the middle of the night and took him to jail.
Another time he won $30,000 in Las Vegas during COMDEX week. The computer industry’s big trade show took over the city every November, and the hotels sold out months in advance, so a man with thirty thousand dollars in his pocket had nowhere to sleep. He slept on the sidewalk. A homeless man took pity on him and tried to figure out why he was sleeping outside.
Bob used the thirty thousand to buy a new 1989 Acura Legend. He sold it to me in 2003 with 220,000 miles on it, and I drove it until 2006. It had 250,000 when I sold it.
In the years I knew him, Bob played his poker at Larry Flynt’s Hustler Casino in Gardena, and he was pretty good at it. Poker was the one game where the house didn’t mind that he was good, because the house wasn’t playing. He was better at backgammon. He won the Los Angeles Open in 1986, in 1989 and again in 2006.
Bob and I spent a lot of evenings over dinner at Brent’s Deli in Northridge, and I’ll always remember him fondly, mostly because of his friends. One of them made a bet that he’d get breast implants. He also lived in a restroom for a month. Gamblers are a different breed.
Joe Russell was the respectable one. He had sold an online betting business for six million dollars and had a hand in several others. He had also won the 1989 World Backgammon Championship in Monte Carlo, and he would later chair the U.S. Backgammon Federation’s board for a decade. The American Backgammon Hall of Fame, which inducted him in 2017, singles out his mathematical acumen and his low-key demeanor. He’s the one who told me about the courier.
Then there was Steve Sax. Not the Dodgers second baseman. This Steve Sax delivered pizzas until he was fifty while making a fortune at backgammon, and in 2002, the year of the exacta grid, he won the American Backgammon Tour. The federation ranks him fourth on the tour’s all-time points list. Every time I talked to Steve, I got the feeling he wasn’t all there. The Hall of Fame, which inducted him in 2019, describes his wit as “dry, wry, and mischievous.”
The three of them went back decades. Bob Dancer played backgammon professionally for almost twenty years before he switched to video poker, most of it at the Cavendish West in West Hollywood between about 1974 and 1993. In 2021 he listed the regulars from that room who were still playing tournaments, and Bob Glass, Steve Sax and Joe Russell were all on the list. “They were all better than me back then,” he wrote. In June 2018, Bob and Steve met in the final of the undefeated bracket at the Los Angeles Open. Between them they had won it eight times.
Robert Aaron Glass died on March 15, 2023. He was seventy.
Internet Explorer Already Called Itself Mozilla
An exacta is a bet on the first two finishers in exact order. In the grid Gus described, the winning horse’s number ran down the left side, the second-place horse’s number ran across the top from 1 to 14, and every cell held the payoff for that combination. Racing is pari-mutuel. A winning combination pays the pool, less the track’s cut, divided by the money bet on that combination, so every new bet moves the prices until the gate opens. A formula that knows what an exacta should pay is useless against a grid that’s a minute old.
I wrote it in Java Swing. The scrapers sent the same headers the browsers of the day sent, so every request looked like a person at a desk running Internet Explorer or Netscape. Several ran at once, each claiming to be a different browser, until the traffic looked like a handful of people refreshing the same page. Internet Explorer 6 on Windows XP introduced itself as “Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1).” Microsoft’s browser had been calling itself Mozilla for years. The web was already full of browsers impersonating each other, and one more fit right in.
It worked until it didn’t. The site started rate limiting, and the limit hit real browsers too. Rate limits don’t read user agents. They count requests, and once this one went up, the disguises bought nothing. The site never needed to know who I was. It counted.
An MCP Server Is the Webmaster Writing Back With Instructions
The right answer was in Gus’s first email, and it had been my idea. “You mentioned that it would be best to contact the site Webmaster,” he wrote. The group had no problem with that, and if it took a subscription, they’d be happy to buy one. In 2002 that was the API. You emailed the webmaster and asked for access.
Anthropic released the Model Context Protocol in November 2024 as an open standard for connecting models to tools and data, and its documentation tells you to think of it like a USB-C port for AI applications. In December 2025, Anthropic donated MCP to the Agentic AI Foundation, a fund under the Linux Foundation that it co-founded with Block and OpenAI. By July 2026 the maintainers were reporting close to half a billion downloads a month across the four Tier 1 SDKs. One of those four is C#.
An MCP server is an ordinary program that exposes capabilities to a model. Mostly that means tools, each with a name, a plain-English description and a JSON Schema for its arguments, along with resources the application can read and prompt templates a user can pick. The application hosting the model, whether that’s Claude, Copilot or an agent you wrote yourself, asks the server for its tool list and puts the names and descriptions in front of the model. When the model decides it needs a tool, the host sends a tools/call request with the arguments the model filled in. The server runs its code and returns the result. Under the hood it’s JSON-RPC 2.0, over standard input and output for a local server or HTTP for a remote one, with OAuth in front of anything worth protecting.
The model never touches the server. It reads descriptions and fills in arguments, which makes the descriptions the most important lines in the whole server. They’re the only documentation the model will ever read.
The current revision of the spec, dated July 28, 2026, made the protocol stateless. The initialize handshake and the session header are gone. Every request carries its own protocol version and client identity, so any request can land on any server instance behind a plain round-robin load balancer. Requests over HTTP also have to carry two new headers, Mcp-Method and Mcp-Name, so a gateway, a firewall or a rate limiter can route and meter calls without opening the request body. The protocol now comes with a place to hang the rate limiter. In 2002 the rate limiter was an ambush.
None of that settles what Gus’s first email was about, which was whether the site would let us in. MCP is wiring between a model and code somebody wrote. If the owner of the data publishes a server or sells you a feed, the code behind your tool is a client with a contract. If they don’t, the code behind your tool is a scraper, and a JSON Schema in front of it doesn’t change what it does to their servers. A USB-C port standardizes the plug. It says nothing about whether you’re allowed to plug in.
The AI industry is the proof. It’s still scraping. In August 2025, Cloudflare published an investigation saying that when sites blocked Perplexity’s declared crawler, Perplexity kept fetching their pages with a generic user agent impersonating Chrome on a Mac, rotating IP addresses and networks, and ignoring robots.txt, across tens of thousands of domains and millions of requests a day. Perplexity called Cloudflare’s errors embarrassing and disqualifying, and said Cloudflare had confused its traffic with BrowserBase, a third-party cloud browser service it uses occasionally. If Cloudflare’s account is right, that’s my 2002 header trick with venture funding that buys you a server farm.
The same Cloudflare post pointed out that ChatGPT Agent signs its HTTP requests with Web Bot Auth, a proposed standard that lets a site verify which agent is knocking. A month earlier, Cloudflare had started blocking known AI crawlers by default on new domains and launched Pay Per Crawl, so a site could charge for access instead of fighting over it. The web is sorting agents into the ones that sign their requests and pay, and the ones that show up in a Chrome costume.
The agents I’ve shipped work against data their owners control. Cara, the shopping assistant on ShopSnap storefronts, runs inside ShopSnap’s own stores. Marisol, the planning agent I built for a Las Vegas wedding chapel, works from the chapel’s own wedding plans. Nobody had to impersonate anything, because the access question was settled before I wrote the first tool. I build MCP servers in C#. One bug in GetXPersonal’s server turned out to be a stored procedure that filtered the search results but not the total, so a search for one city came back with the right profiles and a count for the entire site. MCP passed the wrong count along in valid JSON. The protocol has no way of knowing what the number should be. The fix was a WHERE clause on the count query, and most of the work behind an agent looks like that.
If I rebuilt Joe’s system today, MCP wouldn’t go anywhere near the real-time part. MCP is built for a model to call a tool when it decides it needs one. That puts a model in the loop, and a model needs seconds to decide what to call next, while the exacta grid keeps changing until the gate opens. Language models are slow. Keep them out of any decision that has to be made fast.
A continuous read like mine is still a job for a plain API. The data would come from a licensed tote feed, and ordinary C# code, with tests around the formula, would recalculate the grid every time the pool moved. The agent would sit on top. An MCP tool would hand it the latest grid, and it would answer questions about what came back without ever computing a payoff itself. The subscription Gus offered to buy would be a line item on an invoice.
The Formula Was the Easy Part
The secret formula had public competition. The math for turning win odds into exacta probabilities was published in 1973 by a statistician named David Harville, in the Journal of the American Statistical Association. Whatever was on the Russian’s laptop had to beat a twenty-nine-year-old paper anyone could read in a university library.
The people who do this at scale today are computer-assisted wagering teams, CAW in the trade press. They don’t scrape. They get the tote data directly, many have deals that let them get bets in at the last possible second, and they bet at volumes that move the odds right before the gate opens. On January 30, 2026, the New York Racing Association announced that starting February 5, CAW activity would have to stop at one minute to post in every pool not already restricted. NYRA had shut CAW out of the win pool at two minutes to post back in 2021. It defines CAW by speed. Anything faster than six bets per second counts.
By NYRA’s numbers, it worked. NYRA said CAW had been 20 to 22 percent of its wagering before the new rules and was 12 to 13 percent after. Over the five days of the 2026 Belmont Stakes Festival at Saratoga, CAW betting fell 44.7 percent from the year before, total handle still rose 1.1 percent, and retail handle rose 12.7 percent. David O’Rourke, NYRA’s chief executive, said it was measuring the guardrails’ effect “specifically in the Exacta.” NYRA is also a part-owner of Elite Turf Club, a wagering platform that caters to CAW players.
The rate limit that found my scraper in 2002 found Joe anyway in 2026.
MCP fixed the wiring. Somebody still has to pay the webmaster for access.
