## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, 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 2026-10-18.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (ncrypted_read).
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 75/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 730 tokens (~182/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 7/100
  - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% 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.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 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.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-10-18 (score 68, +1)

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-10-17 (score 67, 0)

## MCP tools (4)

### `ncrypted_create` (~248 tokens)

Create one-time secret

Store a password, API key or sensitive note as a one-time link that self-destructs after a single read. The first 3 per day are free (TTL up to 24h); after that each costs 0.005 USDC, paid via x402 on Base (your MCP client must support x402). Share the link with a person or another agent; never echo the secret in chat. Returns { link, id, receiptToken, expiresAt }; keep id and receiptToken to check delivery (ncrypted_status) or revoke the link (ncrypted_burn). Hosted mode: this server encrypts the secret for you, so it sees the plaintext briefly over TLS (never stored or logged). For end-to-end, zero-knowledge encryption run the local MCP server `npx -y @seidl-family/ncrypted-mcp` instead.

Input parameters:

- `passphrase` (string): Optional second factor the recipient also needs. Share it through a different channel.
- `secret` (string, required): The sensitive value to share. Max 64 KB.
- `ttl_seconds` (integer): Expiry if never read. Default 86400 (24h), max 7 days.

### `ncrypted_read` (~166 tokens)

Read one-time secret

Open an ncrypted link (https://.../s/{id}#{key}) and return the secret. This destroys it permanently. Free. Only use the value for the task at hand and do not repeat it in chat. To check whether someone opened a link you created, use ncrypted_status instead (it doesn't consume anything). Hosted mode: this server decrypts the secret for you, so it sees the plaintext briefly over TLS (never stored or logged). For end-to-end, zero-knowledge encryption run the local MCP server `npx -y @seidl-family/ncrypted-mcp` instead.

Input parameters:

- `link` (string, required): The full ncrypted link including the #key fragment.
- `passphrase` (string): Required only if the sender set a passphrase.

### `ncrypted_status` (~147 tokens)

Check one-time secret status

Check whether a secret you created has been opened yet, without consuming it. Returns { status, expiresAt, readAt? } where status is pending (not opened), read, burned or expired. Use it to confirm delivery, or before deciding to ncrypted_burn a link. Only works for secrets you created (needs their receiptToken); to open a link, use ncrypted_read. Free.

Input parameters:

- `id` (string, required): The secret's id, returned as `id` by ncrypted_create.
- `receiptToken` (string, required): The creator's receipt token, returned as `receiptToken` by ncrypted_create. Only the creator has it; the link alone isn't enough.

### `ncrypted_burn` (~169 tokens)

Burn one-time secret

Permanently destroy an unread secret you created, so its link stops working (e.g. it was sent to the wrong place or is no longer needed). Irreversible. Returns { burned: true } if it was destroyed, or { burned: false, status } if there was nothing left to destroy because it was already read, burned or expired; if it was already read, the recipient has the value, so rotate the credential. Only works for secrets you created (needs their receiptToken). Free.

Input parameters:

- `id` (string, required): The secret's id, returned as `id` by ncrypted_create.
- `receiptToken` (string, required): The creator's receipt token, returned as `receiptToken` by ncrypted_create. Only the creator has it; the link alone isn't enough.

## Common questions

### What is the ncrypted MCP server?

ncrypted is an MCP server listed in the public MCP registry as io.github.Seidl-Family/ncrypted. One-time, end-to-end encrypted secrets for agents. 0.005 USDC per secret via x402. This page covers its hosted endpoint (https://ncrypted.ai/mcp).

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

ncrypted scores 68 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 ncrypted MCP server expose?

ncrypted exposes 4 tools: ncrypted_create, ncrypted_read, ncrypted_status, ncrypted_burn. Their descriptions and schemas cost roughly 730 tokens of context every time the server is loaded.

### Does the ncrypted MCP server require authentication?

No. We connected to ncrypted without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the ncrypted MCP server still maintained?

ncrypted is still listed as active in the MCP registry. We last reached this channel on 18 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
