Radare2 MCP server

This is a helper that connects your AI assistant to Radare2, a well known tool for looking inside program files. It is handy for anyone curious about what a program actually does, or for people who check software for safety. You do not need to be a programmer to try it, but it helps if you are comfortable with technical topics.

What this MCP server does

You ask your AI something about a program file, like what functions it contains or how big they are. Your AI passes that request to this helper, which talks to Radare2 on your computer. Radare2 opens the file, looks at its structure, and sends the details back. Your AI then turns those details into a normal answer in the chat. You can also ask it to run specific Radare2 commands if you know what you want.

What you can do with it

• Open a program file and list the functions inside it
• Show how large each function is and where it sits in the file
• Run Radare2 commands directly through your AI
• Search through a file for specific patterns or text
• Look at the raw bytes and structure of a program
• Work with a file already open in a Radare2 session
• Query analysis results with SQL if the r2xsql plugin is installed

Try asking your AI

• “Open /bin/ls and list its functions”
• “Which functions in this file are larger than 100 bytes?”
• “Show me the strings inside this program”
• “Run the Radare2 command to list all imports in this file”

What it gives back to you

You get back plain answers in the chat, like a list of function names with their sizes, or a summary of what Radare2 found. If you ask for raw command output, you see that text too. Changes only happen if you ask for something that writes, such as running a SQL statement that modifies data.
