hf_fs tool description updated with new grammar options in v0.3.34

Version bumped from 0.3.33 to 0.3.34 and the hf_fs tool's description was updated to document expanded command grammar. Key additions include: new ls flags (-l/-a/-la/-al/--long), cat now accepts an optional RELATIVE_PATH token, find accepts --glob as alias for --name, search now accepts multiple QUERY... tokens, and (-limit|--limit) and (-offset|--offset) short-form aliases are documented throughout. New prose notes clarify that QUERY is optional for repo/collection searches and that multiple QUERY tokens are space-joined.

    Remove hf_doc_fetch, hf_doc_search, and space_search MCP tools

    Three MCP tools have been removed in version 0.3.32: hf_doc_fetch, hf_doc_search, and space_search. Any MCP client or agent workflow that calls these tools by name will now receive an error. Their functionality appears to have been absorbed into the existing hf_fs tool, which gained a new hf://docs URI root, --tag/--kind search flags, and new response fields (category, semantic_relevance, anchor, section).

  • Breaking

    hf_fs tool: op/uri/params replaced with cmd/args in v0.3.31

    The hf_fs MCP tool's input schema has been completely redesigned in v0.3.31. The previous structured parameters (op, uri, glob, recursive, entry_type, name, path, query, sort, max_bytes, offset, limit) have been removed and replaced with two new required fields: cmd (same enum values) and args (a flat string array encoding all arguments as grammar tokens). Any existing client that calls hf_fs with the old op+uri signature will break immediately. Additionally, a new optional warnings array field is added to the response.

    Hugging Face MCP version bump and documentation updates

    Version updated from 0.3.29 to 0.3.30 with documentation knowledge date refreshed to 12 July 2026. Tool titles and parameter descriptions for hf_fs were clarified and expanded to better explain operation modes, URI formats, and filtering behavior, with no changes to the actual API surface or required fields.

  • Additive

    Add paper support to hf_fs tool and consolidate paper_search

    The hf_fs tool now supports browsing Hugging Face papers via new hf://papers URIs and adds paper-related response fields (published_at, daily_papers_date, daily_papers_uri, url, arxiv_url), while the dedicated paper_search tool is removed. Clients using the removed paper_search tool will need to switch to equivalent functionality in hf_fs; however, hf_fs gains additive capability for papers alongside existing models/datasets/spaces/collections support.

  • Breaking

    hf_nav tool removed; its capabilities merged into hf_fs

    The hf_nav MCP tool (Hugging Face Navigation) has been completely removed. Its functionality — including find, search, collection URIs (hf://collections), and related fields — has been folded into the existing hf_fs tool. Any client code that calls hf_nav directly will break; callers must migrate to hf_fs with the new find/search ops and hf://collections URIs.

  • Additive

    Add hf_nav MCP tool for Hugging Face Hub navigation

    A new MCP tool hf_nav has been added to enable navigation and search of Hugging Face Hub entities using hf:// URIs, currently supporting Collections. The tool provides operations for listing, inspecting, and searching Hub content. This is a purely additive change that does not affect existing functionality.

  • Additive

    Add Hugging Face Files tool and add title fields to tools

    New hf_fs tool added to list, read, and stat files from Hugging Face repos and buckets. Several existing tools now include optional title fields for improved UI display, and documentation knowledge cutoff updated to 2 July 2026. These changes are backward compatible and purely additive.

  • Informational

    Hugging Face MCP v0.3.17 capabilities metadata update

    Version bump from 0.3.16 to 0.3.17 with addition of resources and extensions metadata fields to the server capabilities structure. The resources field indicates support for resources with subscription disabled, and extensions indicates support for the Model Context Protocol skills extension. These are informational metadata changes that do not alter the functional API surface.

  • Breaking

    Hugging Face MCP removes resources capability and skills extension

    The server capabilities block no longer advertises the resources capability (listChanged, subscribe) or the extensions block containing io.modelcontextprotocol/skills. Clients that rely on resource listing/subscription or the skills extension will find these features absent from the server's capability negotiation, which will break any integration that checks for or uses those capabilities.
