AI agents and the web
An agent is only as current as the data it can reach. Model weights are frozen at training time, so anything that happened since has to arrive at run time, which puts web access near the centre of agent design. The terms below cover how agents call for web data, the protocols and packaging that make a service usable by an agent, and what happens when an agent drives a browser directly.
How do I give Claude Code or Cursor live web access?
Connect an MCP server that fetches pages, so the assistant gains a tool it can call mid-task instead of relying on what was in its training data.
What is a browser agent?
A browser agent is an AI agent that drives a real browser, deciding what to click and type from what it sees on the page rather than following a script written in advance.
What is a cloud browser?
A cloud browser is a real browser running on someone else's infrastructure that your code connects to remotely, so you get browser capability without running or scaling browsers yourself.
What is a web scraping MCP server?
A web scraping MCP server exposes fetching and extraction as tools an AI assistant can call, so reading a live page becomes part of a conversation rather than a separate script.
What is agentic web scraping?
Agentic web scraping means describing the data you want and letting a model decide which pages to visit and how to pull the fields out, instead of writing selectors against a known page structure.
What is an agent harness?
An agent harness is the code around a model that runs the loop: it sends the prompt, executes the tools the model asks for, feeds results back, and decides when to stop.
What is an agent skill?
An agent skill is a written playbook an agent loads when a task calls for it, telling the model how to use a tool well rather than adding a new tool.
What is Browser Use?
Browser Use is an open-source Python library for building AI agents that control a browser, giving the model a filtered view of interactive elements and letting it choose the next action.
What is LLM grounding?
Grounding means giving a model source material to answer from and requiring it to cite that material, so its output is tied to something checkable rather than to its training data.
What is MCP?
MCP is an open protocol that lets an AI assistant call external tools and data sources through one standard interface, so a service you connect once works in every MCP-compatible client.
What is Playwright MCP?
Playwright MCP is Microsoft's MCP server that lets an AI assistant drive a Playwright browser, using the page's accessibility tree so the model reads structure rather than pixels.
What is web access for AI agents?
Web access is the tooling that lets an agent read live pages at run time, so its answers reflect the current web rather than whatever was in its training data.
What is web scraping for RAG?
It is the ingestion step of a retrieval system: fetching pages, stripping them down to readable text, and splitting that text into chunks that can be embedded and searched.
