What is Plexa?
Plexa is a registry of local businesses in Mexico and Latin America, built so AI assistants (ChatGPT, Claude, Gemini, Perplexity) and autonomous agents can find, read, and recommend them. It gathers more than 10,995 verifiable businesses across 56 cities in 7 countries, with each one's information in the formats machines read: structured data, language-model files, and a query server for agents. For the owner, Plexa is how you exist in AI answers; for a developer or agent, it is the structured source of Latin American local commerce.
The problem it solves
More and more people no longer search on Google: they ask AI («recommend a dentist in Monterrey», «where should I eat tonight in Bogotá?»). AI does not show ten results; it answers with two or three names. And today only 1.2% of local businesses appear in ChatGPT's recommendations (SOCi Local Visibility Index 2026, across hundreds of thousands of locations). The rest are invisible, not because they are worse, but because their information does not exist in the formats AI reads and cites. Plexa attacks that gap from the infrastructure: instead of teaching each business to optimize itself, it aggregates them into a registry that already speaks the language of machines.
How it works, in three layers
For the business
A structured listing with verifiable data (services, hours, location, contact, FAQs) in a format readable by humans and machines (schema.org). The owner claims the listing for free, completes it, and requests their visibility report (the Mirror): a free diagnostic with real data on how they appear to AI today in their vertical and city, and who captures those mentions.
For AI engines
Each listing with server-side rendering and structured data per business type. At the registry level, an llms.txt file (the map those assistants read) and explicit robots.txt permissions for AI crawlers. The crawlers from Claude, Meta AI, ChatGPT, Bing AI, Google, ByteDance AI already read the registry.
For developers and agents
An MCP server (Model Context Protocol) with 7 query tools, published in the official MCP registry, plus an ARD registry (Agentic Resource Discovery), the open standard published in June 2026 by 11 of the largest tech companies (Google, Microsoft, GitHub, Nvidia, Salesforce, and six more), and a REST API. An agent discovers and queries real LATAM businesses without scraping or stale data.
What makes it different
It is a source, not a measurement tool (the measurement, the Mirror, is the entry diagnostic, not the product). It covers the long tail in Spanish that Yelp and Foursquare do not cover well in LATAM. And data honesty is policy: every metric is measured and verifiable, figures are published with a date, and rankings are not for sale. No business pays to appear higher.

Frequently asked questions
What is Plexa?
Plexa is a directory of real businesses designed so that artificial-intelligence agents can find and recommend them. When someone asks ChatGPT, Gemini, or Perplexity about a service in Mexico, Plexa is the structured source these systems can pull verifiable business information from.
How do I get my business to show up when someone asks ChatGPT?
Your business needs to be in a format AI can read and cite: structured, verifiable information that AI crawlers can access. Plexa publishes your business with structured data (schema.org), an llms.txt file, and an MCP server — the standards AI systems use to discover and cite businesses.
How much does it cost to be on Plexa?
Appearing on Plexa is free: any business can be listed and discovered by AI agents at no cost. The Connected plan costs $99 MXN per month for early adopters and includes agentic visibility metrics, priority, and verification. The basic listing never expires and requires no payment.
What is an agentic directory?
An agentic directory is a database of businesses designed to be queried by artificial-intelligence agents, not browsed by people. Instead of pages meant for human eyes, it exposes information through protocols AI systems read directly: schema.org, llms.txt, and MCP (Model Context Protocol).
Is Plexa the same as Google Business Profile or Yelp?
No. Google Business Profile and Yelp are designed for people to read and browse. Plexa is designed for AI agents to query and cite. The difference is the format: Plexa exposes structured, machine-actionable data, not listings optimized for human search.
Which cities and countries does Plexa operate in?
Plexa operates in Mexico and is expanding across Latin America. It currently includes thousands of businesses in dozens of Mexican cities, across verticals such as dental and medical clinics, real estate, restaurants, tourism, professional services, and insurance.
How do I connect an AI agent to Plexa?
You connect your agent to Plexa's MCP server (/mcp/sse) using an API key. From there, your agent can call tools to search businesses by vertical and city, fetch a business's full profile, and access its actionable capabilities. It works with any MCP host: Claude, Cursor, VS Code, and custom agents.
What is the Model Context Protocol and why does Plexa use it?
The Model Context Protocol (MCP) is an open standard that lets AI models connect to external tools and data sources. Plexa uses it because it's the protocol OpenAI, Anthropic, Google, and Microsoft have already adopted, which makes Plexa's businesses accessible to agents without custom integration.
Who is behind Plexa?
Plexa is a project by Christian, an independent founder in Mexico. It is built by AI agents under human supervision. As house policy, every figure is published with a date and rankings are not for sale: no business pays to appear higher in AI answers.
