afs-server 1.0.1

agentic-fs server: stores, services, REST + MCP. Implements the afs-core contracts.

afs-server

The agentic-fs service: the concrete backends (stores, search, extraction), the services, and the REST + MCP surface. Implements the afs-core contracts.

Status

Store layer (in progress):

• afs_server.settings — AFS_* env config; every swappable layer is selected by a backend name and every AWS-shaped backend takes an endpoint_url override.
• afs_server.stores — the store registry: get_object_store(settings) selects a builtin or an installed plugin (afs.object_stores entry-point group).
• afs_server.stores.objects_s3.S3ObjectStore — the S3 ObjectStore. Because it speaks plain S3, it is your store for any S3-compatible endpoint (MinIO, Cloudflare R2, Wasabi, Backblaze B2) via AFS_S3_ENDPOINT_URL — no code change.
• afs_server.stores.catalog_dynamodb.DynamoDBCatalogStore — the DynamoDB CatalogStore over the single-table schema (AFS_DYNAMODB_ENDPOINT_URL points at DynamoDB Local for dev).

Both stores are certified by the afs-core conformance kits via moto.

• afs_server.services.FsService — the read path (list / stat / ranged read) over the stores, with scope + namespace enforcement and 404-not-403 misses.
• afs_server.app — the FastAPI app: /v1/healthz, /readyz, /me, and fs/{ns}/{entries,stat,doc}; dev auth (static principal, never prod); every AfsError rendered as RFC 9457 problem+json.
• afs_server.mcp — the MCP surface mounted at /mcp (FastMCP): whoami, fs_list, fs_stat, fs_read over the same FsService (in-process, no HTTP self-calls). The full middleware chain + remaining tools land with their slices.

The image (../../Dockerfile) runs this app on Lambda / Fargate / locally; make dev from the repo root runs it against MinIO + DynamoDB Local. Coming next: the MCP mount (shares FsService in-process).

Swapping a backend (plug-and-play)

See docs/swap-guides/. In short: S3-compatible storage needs only an env var; anything else implements the ObjectStore Protocol, registers an entry point, and certifies against afs_core.testing.ObjectStoreConformance.
