A side-by-side look at the 2Captcha MCP and Binary Ninja MCP MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose 2Captcha MCP for communication work as a local process; choose Binary Ninja MCP for security as a local process. You can also run both side by side in one mcpServers block.
