Free MCP tools
Small, free, no-signup tools for the annoying parts of working with MCP configs. Each runs entirely in your browser — paste a config, get an answer, nothing leaves your machine.
Config generator
Pick one or more servers from the directory and get a single merged config in the exact shape your client needs.
Open toolConfig validator
Paste your mcpServers JSON; catch the silent errors clients fail on (trailing commas, smart quotes, bad nesting) and format it.
Open toolConfig converter
Move a config between Claude Desktop, Cursor and Windsurf — remote-transport differences rewritten automatically.
Open toolConfig doctor
Paste a config and check it against the tool budget and quality signals — before the agent starts misbehaving.
