## MCP tools (10)

### `register` (~68 tokens)

Create an account and send a verification email. The 30-day free trial includes 100 image uploads total, shared across API, SDKs, MCP and dashboard. This allowance does not renew monthly. Cannot replace an already configured runtime.

Input parameters:

- `email` (string, required)
- `password` (string, required)

### `verify_email` (~33 tokens)

Verify an email token and save credentials locally. Refuses to replace an already configured runtime.

Input parameters:

- `token` (string, required)

### `upload_asset` (~167 tokens)

Upload a supported image, video, PDF, font or text asset. Acceptance is not readiness: wait for processed before sharing. Project-user scoped upload keys restrict uploads to their identity. The 30-day free trial includes 100 image uploads total, shared across API, SDKs, MCP and dashboard. This allowance does not renew monthly.

Input parameters:

- `data` (object): At most five scalar fields; UTF-8/encoded size limits apply
- `file_path` (string): Local file path; provide exactly one file source
- `file_url` (string): HTTP(S) file downloaded on the MCP machine, then uploaded
- `private_url_expires_in` (integer)
- `quality` (string): Video quality only; availability depends on the plan
- `visibility` (string)

### `get_asset_status` (~42 tokens)

Inspect processing status and delivery information. Scoped keys only read uploads owned by their identity. A URL is ready only for active processed assets.

Input parameters:

- `asset_id` (required)

### `list_assets` (~93 tokens)

List uploaded files in the configured project, with pagination and processing/deletion filters. A scoped key lists only its identity uploads. KOMPRESSR_PROJECT_ID is required.

Input parameters:

- `data` (object)
- `deletion_status` (string)
- `external_id` (string)
- `limit` (integer)
- `page` (integer)
- `status` (string)
- `visibility` (string)

### `generate_private_url` (~63 tokens)

Generate a fresh expiring URL after private upload processing and application access checks. Scoped keys only sign their own identity private uploads. Expiry does not delete the asset.

Input parameters:

- `asset_id` (required)
- `expires_in` (integer)
- `variant` (string)

### `wait_for_asset` (~70 tokens)

Wait within a bounded time budget for an active upload to process. A timeout preserves the asset ID; resume rather than reupload. Private uploads need generate_private_url after readiness.

Input parameters:

- `asset_id` (required): Positive numeric asset ID; not a URL or external customer ID
- `timeout_ms` (integer)

### `get_asset_deletion_status` (~54 tokens)

Inspect processing/deletion state and storage credits for an asset ID. File removal completion does not certify that all caches have cleared.

Input parameters:

- `asset_id` (required): Positive numeric asset ID; not a URL or external customer ID

### `delete_asset` (~62 tokens)

Permanently delete one explicit asset ID. Irreversible; no restore or cancellation. Scoped keys need explicit delete permission. Acceptance starts background cleanup; cached/offline copies may remain.

Input parameters:

- `asset_id` (required): Positive numeric asset ID; not a URL or external customer ID

### `bulk_delete_assets` (~54 tokens)

Permanently delete 1–100 explicit asset IDs. Inspect each result: a successful HTTP request can contain failed items. Scoped keys require delete permission. No query-based deletion or undo.

Input parameters:

- `asset_ids` (array, required)

## Common questions

### What is the Kompressr MCP server?

Kompressr is an MCP server listed in the public MCP registry as com.kompressr/kompressr. Upload, optimize and manage files, wait for processing, and generate private delivery links. This page covers its npm package (@kompressr/mcp-server).

### Is the Kompressr MCP server safe to use?

Kompressr scores 85 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Kompressr MCP server expose?

Kompressr exposes 10 tools: register, verify_email, upload_asset, get_asset_status, list_assets, and 5 more. Their descriptions and schemas cost roughly 706 tokens of context every time the server is loaded.

### Is the Kompressr MCP server still maintained?

Kompressr is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Kompressr MCP server under?

Kompressr declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
