MCP Lint
A VS Code extension that checks MCP server source as you write it: missing tool descriptions, malformed input schemas, duplicate names and bloated descriptions.
Other MCP tooling points at a running server after the fact. This one watches the file you are editing, the way ESLint does, and reports problems as you type, most of them with a one-click fix. It can also scan a whole workspace, and run the MCP Inspector CLI against the current file.
The analyzer is syntax-level heuristics on the TypeScript compiler API. It reasons only about literal arguments, and skips anything passed in through a variable rather than guessing.
