Roboflow Cloud Storage

For agents: This skill is authored in roboflow/computer-vision-skills. If your client already has it loaded as a skill (for example from a Roboflow plugin), use that copy. The skill://roboflow/<name>/SKILL.md MCP resources serve the same skills for clients that don't have them loaded.

Cloud Storage (Datasources & Credentials)

Mirror a cloud bucket's contents into a Roboflow workspace so new objects flow in automatically. Two pieces work together:

• Credential — the secret Roboflow uses to reach the bucket (stored, masked server-side, reusable across datasources).
• Datasource — a bucket-mirror configuration: which bucket (via a credential), which objects (glob rules), and how they sync. "Datasource" is the user-facing name; the platform stores it as a bucket-mirror config.

Imports land at the workspace level. The datasource API cannot target a specific project/dataset today.

Only want to run a model/Workflow over the files and collect the outputs, without importing anything into Roboflow? That is batch processing — see the roboflow-batch-processing skill. Mirroring composes with it too: imported files become Asset Library images, and bulk predictions over them run as Asset Library batch processing jobs (same skill).

Fast path — one call

connect_cloud_storage does the whole flow in one shot: (optionally) create a credential, create the datasource, validate access, and start the first mirror run. Prefer it for new setups.

• Reuse a credential: pass credential_id (from credentials_list).
• Create a new credential: pass credential_name + credential_type (the secret is collected securely out-of-band — see Security).
• Describe the datasource so it can be created first: bucket_type (s3/gcs), bucket_name, region, plus optional mirror_configs glob rules (see Datasources). The datasource must exist before anything can be validated or triggered — there is nothing to mirror without it.
• trigger (default true) starts a mirror run only if validation passes; triggering consumes credits.
• Returns {credentialId, credentialCreated, datasourceId, validation, triggered, batchIds?}. If a new credential was created but a later step failed, you get status: "partial" with the ids so you can clean up with credentials_delete / datasource_delete.

Credentials

Security — secrets never enter the chat

The secret (keys, service-account JSON, password) is collected out-of-band via MCP elicitation, never as a tool argument and never in the transcript or model context. credentials_list returns only masked, non-secret fields. If your client can't elicit securely, the tool returns manual_entry_required with a URL to create the credential in the app (app.roboflow.com/<workspace>/settings/datasources), then call credentials_list to get its id.

Credential types

AWS PrivateLink (require_vpce) requires an AssumeRoleWithWebIdentity credential; the server rejects the datasource otherwise.

Datasources

Bucket

• bucket_type: s3 or gcs
• bucket_name (no scheme/path), region (e.g. us-east-1)
• endpoint: custom URL for S3-compatible providers (S3 only)

Mirror rules (mirror_configs)

Optional list; omit to mirror the whole bucket with default settings. Each rule selects a subset and controls sync behavior:

• glob_patterns (list) — the key field. Selects objects, e.g. ["images/**/*.jpg", "batch-*/**"]. Set it to avoid importing unwanted files or to split a bucket into multiple rules. Omit only when you truly want everything.
• glob_file_path — alternative: path to a manifest file in the bucket whose lines list object paths to import.
• id — rule id (auto-generated; pass an existing id on update to edit in place).
• settings (omitted keys use server defaults):
  • removeOrphanedSourcesWhenDisappeared (default true) — delete mirrored images when the source object is removed.
  • namingStrategy (fullPath|fileName|eTag|metadata, default fullPath); namingStrategyMetadataKey required when metadata.
  • updateImageWhenNewer (true) / updateImageStrategy (overwrite).
  • updateMetadataWhenNewer (true) / updateMetadataStrategy (mergeBucketWins default; also overwrite|merge|mergeUserWins| untilFirstChange|append).
  • runScheduledEvery (hours, default 0 = off) — >0 enables a recurring mirror (fixed 24h cadence today; only on/off is honored).

Lifecycle & validation

1. Create (datasource_create, or connect_cloud_storage). Nothing is mirrored yet.
2. Validate (datasource_validate) — checks listFiles, headFile, getFile, and per-rule headGlobFile; returns {checks, errors}. Run it to self-diagnose a bad credential/bucket before triggering.
3. Trigger (datasource_trigger) — starts the mirror job; consumes compute/storage credits. Returns {batchIds}.
4. Poll (datasource_job_get with a batchId) — status (running/completed/failed), per-stage counters, errors, timestamps.

Update (datasource_update): only fields you pass change; to change the bucket pass bucket_type + bucket_name + region together. Delete (datasource_delete): removes the config, not already-mirrored images. Deleting a credential still referenced by a datasource makes its runs fail.
