# hub-query-staging

This staging 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=huggingface`
- `FAST_AGENT_OAUTH_SCOPES=inference-api`
- `--instance-scope request`

The README enables Space OAuth (`hf_oauth: true`) and the container sets the fast-agent OAuth environment. `SPACE_HOST` is used by fast-agent to derive the public OAuth resource URL. No shared `HF_TOKEN` is required for user-scoped OAuth/token pass-through.

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:sambanova`

## Main files

- `hf-hub-query.md` — raw MCP card
- `tool_entrypoints.py` / `monty_api/` — Hub query tool implementation
- `_monty_codegen_shared.md` — shared codegen instructions
- `wheels/fast_agent_mcp-0.8.0-py3-none-any.whl` — staging fast-agent wheel from `../fast-agent-pr/`

## Dependencies

The Space installs the staged `fast-agent-mcp` wheel from this repo and `pydantic-monty==0.0.17` from PyPI.
