AI Tools
Developer utilities for building with AI - MCP configuration, Model Context Protocol tools, and more. All free and browser-based.
Questions
Are these tools free?
Yes. No account, no trial period, no usage limits. The MCP config generator and the token counter both run in your browser, so there is nothing for us to meter.
What is MCP?
The Model Context Protocol is an open standard for connecting AI assistants to external tools and data. An MCP server exposes capabilities; a client such as Claude Desktop, Cursor or VS Code connects to it. The config generator writes the JSON each client expects, since the shape differs between them.
Does the token counter send my text anywhere?
No. The tokenisers run in the page. For models with a published tokeniser, such as the Claude and GPT families, the count is exact. For the rest it is an estimate using a comparable encoding, and the page says which you are looking at.
Do you store the MCP configs I build?
Only if you choose to share one, and share links strip environment variable values and keep the keys. Nothing is written to a server otherwise.
