## 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**: 0/100
  - 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 could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).
  - Install-script risk not yet assessed.
  - Dependency health could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).
- **Provenance & Transparency**: 6/100
  - Repository check failed: no source repository is declared.
  - Provenance check failed: no build-provenance attestation is published.
  - License check failed: the license (Proprietary) isn't a recognized OSI-approved license.
  - Actively maintained (last published 34 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 77/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 232 tokens (~116/item across 2 items; 2 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 93/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 80% 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 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 2 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## Install

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

KeySlip 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, 31c49b2b0c11a2d13e0c1e4003fce773bc8dd69556fde19ac83f80169528672a; the commands to do that are on this page. If it does not match, do not open it.

## MCP tools (2)

### `send_secret` (~103 tokens)

Criptează în procesul local și păstrează mesajul în KeySlip pentru o singură citire. Trimite linkul întreg doar destinatarului; cheia rămâne în fragmentul linkului.

Input parameters:

- `expire` (string)
- `password` (string): Parolă suplimentară opțională, comunicată separat.
- `text` (string, required): Mesaj UTF-8, cel mult 32.000 de octeți.

### `read_secret` (~129 tokens)

Consumă mesajul din KeySlip o singură dată, îl șterge de pe server și îl decriptează local. Cere acordul destinatarului înainte de citire. Nu deschide automat linkuri și nu reîncerca: o parolă greșită sau o conexiune întreruptă poate pierde mesajul. Linkul trebuie trimis doar destinatarului.

Input parameters:

- `link` (string, required): Linkul complet, inclusiv cheia după #.
- `password` (string): Parola suplimentară, dacă expeditorul a setat-o.

## Common questions

### What is the KeySlip MCP server?

KeySlip is an MCP server listed in the public MCP registry as app.keyslip/keyslip. Send and read one-time encrypted secrets with local encryption. This page covers its MCPB bundle (https://github.com/dobrician/keyslip-distribution/releases/download/v1.3.0/keyslip-linux-x64.mcpb).

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

KeySlip scores 47 out of 100 on VerifyMCP. 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 KeySlip MCP server expose?

KeySlip exposes 2 tools: send_secret, read_secret. Their descriptions and schemas cost roughly 232 tokens of context every time the server is loaded.

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

KeySlip declares the Proprietary licence, which is not on the OSI-approved list. Read the terms before using it at work, and note this covers the source only, not the cost of any service it calls.

### What did VerifyMCP test on the KeySlip MCP server?

VerifyMCP ran 12 checks on KeySlip, covering Source repository, Provenance, License, Maintenance and 8 more. 4 items could not be completed, a gap on our side rather than a finding about KeySlip: Malware scan, Known CVEs, Install scripts and Dependency health. One category scores 0 for that reason, because we only credit what we can confirm. Endpoint Security and Transport & Reachability do not apply to an MCPB bundle, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
