## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Supply Chain Security**: 23/100
  - No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.
  - Known CVEs were checked across the 93 of 93 dependencies we could resolve, so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - 30 of 93 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 48/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 11 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 64/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 706 tokens (~70/item across 10 items; 10 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 57/100
  - Stability observed for 17 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 76/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 28% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - All 2 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Install

### How do I install the Kompressr MCP server?

Kompressr ships as an MCPB bundle, a single file you download and open in an MCP host that supports MCPB bundles, such as Claude Desktop. The host reads the launch command from the bundle's own manifest, so there is no command to copy. Before opening it, check the file's SHA-256 matches the one the MCP registry declares for it, 207031d72bbe2b3cc5c8373024bdb86c19841e92387c665bd9d7457100639f97; the commands to do that are on this page. If it does not match, do not open it.

## 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 MCPB bundle (https://github.com/kompressrcdn/clients/releases/download/mcp-server-v2.0.3/kompressr-2.0.3.mcpb).

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

Kompressr scores 52 out of 100 on VerifyMCP. It declares no install or post-install scripts. 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.

### 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.
