A project's .openidea/settings.toml could loosen what coding agents do without asking: auto-approve commands, empty the blocked list, pick the mode new tasks start in, and add MCP servers every agent session starts. Project settings can no longer set agentSecurity.allowedCommands or agents.defaults (user settings only, like mcpServer), and a project's agentSecurity.blockedCommands adds to the user's list instead of replacing it. Workspace MCP servers start only once the user has turned that exact definition on in Settings › Agents › External MCP Servers; servers saved there count as turned on, servers imported or changed in the file stay off until turned on. The Command Execution Policy page drops its Global / This project switch. Co-authored-by: rohitdanda <10144914+rohitdanda@users.noreply.github.com>

OpenIDEA brings the IntelliJ IDEA way of working — its keymap, its tool windows, its search-everything habits — to a native app with a Rust core.
Editor, code insight, debugger, Git, terminal, database and HTTP clients, for 60+ languages. Builds for macOS, Windows and Linux.
Benchmark
Opening freqtrade (Python, ~770 files) with warm caches, median of 5 runs:
| OpenIDEA | IntelliJ IDEA 2026.2.3 | |
|---|---|---|
| Window with the project | 0.9 s | 3.1 s |
| Ready (CPU settled) | 1.1 s | 13.2 s |
| Memory (USS, all processes) | 169 MB | 2011 MB |
| CPU time until ready | 2.4 s | 47.9 s |
| Idle CPU | 4 % of a core | 7 % of a core |
| Quit | 0.3 s | 5.9 s |
A release build of OpenIDEA from main and IDEA with default settings and plugins, on
Windows 11, 32-core AMD, 62 GB RAM.
IDEA analyses Python more deeply, so "ready" doesn't mean the same work on
both sides. Both are measured from the outside, the same way: see
perf/compare to run it on your machine and projects.
Plugins
Plugins add actions, completion, quick fixes, tool windows, custom editors, themes, file icons and languages. They run as sandboxed WebAssembly components; themes, icon themes and languages need no code at all.
Install them from Settings › Plugins, or start your own with
openidea-plugin new — see Writing OpenIDEA plugins and
the official plugins. The plugin API is still a preview.
