1111The Filesystems Working Group exists to make MCP Resources bidirectional, so that an agent can write a result back to
1212the server it reads its inputs from. Agent platforms are converging on presenting services to models as filesystems, and
1313Resources already addresses content by URI under a [`file://` scheme the specification defines as identifying "resources
14that behave like a filesystem"](/specification/draft/server/resources#common-uri-schemes). Currently, Resources carries
14that behave like a filesystem"](https://modelcontextprotocol.io/specification/draft/server/resources#common-uri-schemes). Currently, Resources carries
1515that surface in the read direction. The WG will produce a single Extensions Track SEP covering write operations,
1616optimistic concurrency control, and the interaction with change notification and caching.

4848* **File Uploads WG.** Both groups transfer content to a server. Coordination needed on where an upload-oriented flow
4949 ends and a resource write operation begins.
50* **[Skills Over MCP WG](/community/working-groups/skills-over-mcp.md).** The published
51 [Skills extension](/extensions/skills/overview.md) uses Resources for file reads and defines optional directory reading.

5252 It does not depend on filesystem write operations; coordinate on future resource operations that affect skills.
5353* **Agents IG.** Multi-agent and job orchestration systems are the motivating consumers of a shared write path.
