A side-by-side look at the 2Captcha MCP and Scrivener 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 Scrivener MCP for knowledge & memory as a local process. You can also run both side by side in one mcpServers block.
TWOCAPTCHA_API_KEY.twocaptcha_solve_normal, twocaptcha_solve_text, twocaptcha_solve_audio.Rows where the two servers differ are marked.
