MCP stdio server for radare2
Radare2 MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. MCP stdio server for radare2.
An MCP server to use radare2 with AI agents such as OpenCode, Mai, VSCode, Claude, CLION, ...
Once Radare2 is connected, these are the calls the assistant has available:
macOS — ~/Library/Application Support/Claude/claude_desktop_config.jsonWindows — %APPDATA%\Claude\claude_desktop_config.jsonCodex — This will create a personal marketplace in your home and copy the files from dist/codex-plugin insideSetup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.
You will need one environment variable: R2MCP_AUTH_TOKEN. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Radare2's toolset — macOS, Windows, Codex — is a fair guide to whether it matches your workflow. It is maintained by dnakov; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
