IDE chat goes multi-agent
GoLand’s 2026.1 update adds AI chat support that can hook into Cursor, Copilot and Claude via an Agent Client Protocol, effectively letting IDEs become agent hosts rather than closed assistants. That change makes installing and switching agents inside a development environment easier and reinforces the trend toward composable, terminal‑friendly AI tooling. (x.com)
A code editor used to come with one built-in assistant, the way a car comes with one radio. GoLand 2026.1 changes that by letting its chat window connect to outside coding agents like GitHub Copilot and Cursor instead of only JetBrains’ own tools. (blog.jetbrains.com) An integrated development environment is the main workbench where programmers edit files, run tests, and inspect errors. JetBrains has been turning that workbench into something other tools can plug into, not just something developers type into. (jetbrains.com) The plumbing behind this is called Agent Client Protocol, which is a shared language between an editor and an artificial intelligence agent. JetBrains says the protocol lets any agent that speaks that language connect without a custom one-off integration. (jetbrains.com) That is the same basic idea as Universal Serial Bus for keyboards and mice: once the port is standard, the accessory matters more than the socket. JetBrains and the Zed editor team say they built Agent Client Protocol as an open source way to connect local, remote, or in-house agents without vendor lock-in. (jetbrains.com) In GoLand 2026.1, that means the chat panel can now work with GitHub Copilot, Cursor, and other agents listed in the new registry, alongside JetBrains’ Junie, Claude Agent, and Codex. JetBrains says developers can install compatible agents from a curated registry or add them manually. (blog.jetbrains.com) (jetbrains.com) The registry matters because agent setup has been messy for most of the past year. Instead of hunting through GitHub pages and command-line flags, developers get a one-click catalog inside the editor, which JetBrains is also rolling out across other 2026.1 products like Rider. (jetbrains.com 1) (jetbrains.com 2) This is the second half of a bigger shift JetBrains started earlier. Since GoLand 2025.2, the editor has also shipped an integrated Model Context Protocol server, which lets outside clients like Claude Desktop, Cursor, Codex, and Visual Studio Code control IDE tools from their own side. (jetbrains.com) Put those two pieces together and the editor stops being a sealed app. One standard lets GoLand call outside agents through Agent Client Protocol, and another standard lets outside agents call GoLand tools through Model Context Protocol. (jetbrains.com 1) (jetbrains.com 2) That is why this release feels bigger than a chat feature. The winning development setup in 2026 is starting to look less like “pick one assistant forever” and more like “swap agents the way you swap terminals, shells, or linters,” with the integrated development environment acting as the host instead of the gatekeeper. (jetbrains.com) (agentclientprotocol.com) You can already see that ecosystem forming around the protocol. The public agent list includes Gemini Command Line Interface, Goose, Cline, GitHub Copilot in public preview, and adapters that let Claude Agent and Codex Command Line Interface work through the same client layer.
