inputSchema with ZodRawShape

[lanluu]

I am using the latest release 1.17.3.

I registered a tool as below

server.registerTool(
        "get_file_contents",
        {
            title: "Fetch File Content",
            description: "Fetches the content of a file from either Github or Gitea, given repository details and authentication token.",
            inputSchema: {
                url: z.string().describe("The base URL of the repository (Github or Gitea)."),
                token: z.string().describe("Authentication token for the repository."),
                branch: z.string().describe("The branch name to fetch the file from."),
                owner: z.string().describe("The owner of the repository."),
                repo: z.string().describe("The name of the repository."),
                path: z.string().describe("The path to the file within the repository.")
            }
        },
...

Well, as registerTool expects an inputSchema as ZodRawShape, my given code should work. But in this case, the following error appeared by each property of inputSchema:

Type 'ZodString' is missing the following properties from type 'ZodType<any, any, any>': _type, _parse, _getType, _getOrReturnCtx, and 7 more.ts(2740)
types.d.cts(14, 5): The expected type comes from this index signature.

Any tip or help is much appreciated!

use zod v3; faced the same error but v3 solved it

I use Zod V3 (3.25.76) also. What did you mean "v3 solved it"? :-)

[MyRichard12]

I mean is there a way for you to explicitly infer zod/v3, in your import..

I actually use zod 4.0.17

But i inferred
import z from "zod/v3";
in the MCP tooling script

And the error disappeared

Thank you for your hint @MyRichard12 !
