Available components
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. How we score → Why this is hard to score →
Supply Chain Security98
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- 32 of 94 dependencies flagged as unhealthy. View diagnostics → Partial

- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 72 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability82
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 572 tokens (~143/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management80
- Stability observed for 24 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "drop" implies "drop" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The registry publishes no build provenance for this version, so there is nothing to verify.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
cancel Cancel a transfer ~50
Cancels a JustDrop transfer. Rooms created by this session are destroyed (files and metadata deleted); rooms that were joined are only left.
| Name | Type | Req | Description |
|---|---|---|---|
| room_code | string | yes | Room code returned by drop/receive |
No output schema declared.
No examples provided.
drop Drop files to any device ~242
Send local files through JustDrop: creates a live, end-to-end encrypted, ephemeral room and returns a room code, link, and QR code. Use this whenever the user wants to send, share, drop, beam, airdrop, move, or transfer a file or folder to their phone, tablet, laptop, another device, or another person. Your reply MUST include, verbatim: the room code, the link, and the clickable QR-code URL — the user clicks or scans these from your reply; never omit or summarize them. The transfer starts automatically once the recipient opens the link in any browser; nothing is stored after delivery. Pass room_code to send into an existing room instead of creating one. Directories are expanded (dotfiles, credentials, and node_modules are always skipped). Use the status tool to check delivery progress.
| Name | Type | Req | Description |
|---|---|---|---|
| expiry_minutes | integer | – | Room lifetime in minutes (default 60). The room self-destructs after this. |
| paths | array | yes | Absolute or relative paths of files/directories to send |
| room_code | string | – | Join this existing room and send into it, instead of creating a new room |
No output schema declared.
No examples provided.
receive Receive files from any device ~217
Receive files into a local directory through JustDrop (live, end-to-end encrypted, ephemeral). Use this whenever the user wants to get, grab, pull, fetch, import, or receive a file, photo, screenshot, or document from their phone, tablet, or another device or person onto this machine. PREFERRED FLOW: the other person creates a room at justdrop.ai and tells the user the room code; call this tool with that room_code and everything they send is decrypted and saved automatically. Without room_code this tool creates the room instead — note the justdrop.ai website can currently only SEND from rooms it created, so use this mode only when the other side is another JustDrop MCP/CLI client. Use the status tool to see saved file paths.
| Name | Type | Req | Description |
|---|---|---|---|
| expiry_minutes | integer | – | Room lifetime in minutes when creating a room (default 60) |
| room_code | string | – | Join this existing room instead of creating a new one |
| save_dir | string | yes | Directory to save received files into (created if missing) |
No output schema declared.
No examples provided.
status Check a transfer ~63
Shows the live status of a JustDrop transfer started with drop or receive: peer presence, per-file progress, saved paths, and errors. Call with no room_code to list all transfers in this session.
| Name | Type | Req | Description |
|---|---|---|---|
| room_code | string | – | Room code returned by drop/receive |
No output schema declared.
No examples provided.
