short_description: Raw fast-agent MCP server for HF Hub queries.

# hf-hub-query

This Space runs a raw-passthrough fast-agent MCP server backed by the custom Monty build used for Hugging Face Hub querying.

The deployed card uses `tool_result_mode: passthrough`, so tool results are returned directly rather than rewritten by a second LLM pass.

## Auth

This Space is configured for Hugging Face OAuth/token passthrough:

- `FAST_AGENT_SERVE_OAUTH=hf`
- `FAST_AGENT_OAUTH_SCOPES=inference-api`
- `--instance-scope request`

These are configured as Space settings:

- Variables:
  - `FAST_AGENT_SERVE_OAUTH`
  - `FAST_AGENT_OAUTH_SCOPES`
  - `FAST_AGENT_OAUTH_RESOURCE_URL`
- Secret:
  - `HF_TOKEN` (dummy startup token)

Clients can either:
- send `Authorization: Bearer <HF_TOKEN>` directly, or
- use MCP OAuth discovery/auth flow

## Model

The deployed card uses:

- `hf.openai/gpt-oss-120b:cerebras`

## Main files

- `hf-hub-query.md` — raw MCP card
- `monty_api_tool_v2.py` — Hub query tool implementation
- `_monty_codegen_shared.md` — shared codegen instructions
- `wheels/pydantic_monty-0.0.7-cp313-cp313-manylinux_2_34_x86_64.whl` — custom Monty wheel

## Note on the Monty wheel

The bundled wheel is a CPython 3.13 `manylinux_2_34_x86_64` build for better HF runtime compatibility.
