Same PR as huggingface/huggingface_hub#3166 in Python.

This PR introduces breaking changes but I think it's best to do it now. Goal is to have the same format as VSCode MCP config e.g.

{
  "model": "Qwen/Qwen2.5-72B-Instruct",
  "provider": "nebius",
  "inputs": [
    {
      "type": "promptString",
      "id": "hf-token",
      "description": "Token for Hugging Face API access",
      "password": true
    }
  ],
  "servers": [
    {
      "type": "http",
      "url": "https://huggingface.co/mcp",
      "headers": {
        "Authorization": "Bearer ${input:hf-token}"
      }
    }
  ]
}

breaking changes:

  • no more config nested mapping => everything at root level
  • headers at root level instead of inside options.requestInit
  • updated the way values are pulled from ENV (based on input id)

Once this PR and huggingface/huggingface_hub#3166 are approved, we can merge + release them at the same time + update the config in https://huggingface.co/datasets/tiny-agents/tiny-agents to follow the new convention. For now, only wauplin/library-pr-reviewer has been updated for testing.

pnpm run cli run wauplin/library-pr-reviewer

EDIT: PR merged and released. Made a release on Python SDK as well and updated all configs in https://huggingface.co/datasets/tiny-agents/tiny-agents.

clean!

import { stdin, stdout } from "node:process";
import { z } from "zod";
import { PROVIDERS_OR_POLICIES } from "@huggingface/inference";
import type { ServerConfig } from "@huggingface/mcp-client";

a bit confusing to have the same name for something different in mcp-client vs. tiny-agent, but I guess this one's on me 😀

i guess we could potentially rename the one in mcp-client to McpServerConfig but 🤷

looks good, thank you!

EDIT: We should remove the "config" nested mapping in https://github.com/huggingface/huggingface.js/blob/main/packages/tiny-agents/test/ServerConfigSchema.spec.ts

Fix docs example after
huggingface/huggingface_hub#3166 /
#1556. Since release
[0.33.2](https://github.com/huggingface/huggingface_hub/releases/tag/v0.33.2)
`tiny-agents` config follow VSCode format. We made the change without a
proper deprecation warning as it's still experimental and we wanted to
harmonize with VSCode as quickly as possible (to avoid future
conflicts).
