Describe the bug
Hi! I am working on a wrapper tool around server.tool that allows you to define a tool with custom options called registerPaidTool.

I am trying to have registerPaidTool have a similar function signature to server.tool where the paramsSchema type defines the callback function:

export async function registerPaidTool<Args extends ZodRawShape>(
  mcpServer: McpServer,
  toolName: string,
  toolDescription: string,
  paramsSchema: Args,
  // @ts-ignore
  paidCallback: ToolCallback<Args>,
  options: PaidToolOptions
) {

However, the line paidCallback: ToolCallback<Args> results in "Type instantiation is excessively deep and possibly infinite.ts(2589)" (hence the @ts-ignore). I have also noticed this slows down the Typescript server in my IDE.

Full code here:
https://github.com/stripe/agent-toolkit/blob/main/typescript/src/modelcontextprotocol/register-paid-tool.ts#L22

To Reproduce
Steps to reproduce the behavior:

1. Clone https://github.com/stripe/agent-toolkit/blob/main/typescript/src/modelcontextprotocol/register-paid-tool.ts#L22
2. Delete the // @ts-ignore above paidCallback
3. In the typescript/ folder, run pnpm run build

Expected behavior
I would expect this error not to show up.

I am curious if anyone has run into this problem - am I doing something incorrect here, or is ToolCallback<Args> inherently too complex for the TS compiler since it has multiple zod schemas under the hood?

Thank you!
