THEN Modify the tool's input schema to replace any array-of-objects parameter with a type that Claude Desktop supports. For example, accept a single string that contains a JSON-encoded array of objects, then parse it server-side. Alternatively, use an array of strings (e.g., alternating oldText and newText) or an array of arrays. This workaround sidesteps a Claude Desktop limitation that prevents tools with array-of-objects parameters from appearing in the tool list.

// Instead of: edits: z.array(z.object({ oldText: z.string(), newText: z.string() }))
// Use: editsJson: z.string() // JSON string, then server parses
const args = JSON.parse(editsJson);
