## 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**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs setuptools.build_meta at install time, a recognised build step with no custom scripting around it.
  - 0 of 12 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to Maytrella007/protonlite).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 13 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 62/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 892 tokens (~49/item across 18 items; 18 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 75/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 0 of 3 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "send_message" implies "send" and declares no destructiveHint at all, which the MCP spec reads as destructive by default.
  - An AI judge read all 18 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.

**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.

First indexed and scored.

## MCP tools (18)

### `list_messages` (~52 tokens)

List messages in a Proton Mail folder (inbox, sent, archive, spam, trash, starred...).

Input parameters:

- `folder` (string)
- `limit` (integer)
- `unread_only` (boolean)

Output parameters:

- `result` (string)

### `read_message` (~32 tokens)

Read one Proton Mail message by id, decrypted, with HTML flattened to prose.

Input parameters:

- `message_id` (string, required)

Output parameters:

- `result` (string)

### `search_messages` (~32 tokens)

Find messages whose sender or subject contains the query.

Input parameters:

- `limit` (integer)
- `query` (string, required)

Output parameters:

- `result` (string)

### `send_message` (~148 tokens)

Send an email. Plain text by default; set html=true to send the body as HTML.
attachments is a list of local file paths to attach, e.g. a file you just fetched
with drive_download. A send is refused if a recipient is not on the allowlist
(see email_policy_status / email_allow). When the confirm-before-sending rule is
on, the first call sends nothing and returns a confirmation request; call again
with confirm=true once the person has approved.

Input parameters:

- `attachments`
- `body` (string, required)
- `confirm` (boolean)
- `html` (boolean)
- `subject` (string, required)
- `to` (array, required)

Output parameters:

- `result` (string)

### `email_policy_status` (~51 tokens)

Show the send policy: which recipients the allowlist permits (or that it is open),
any hard ceiling set by the PROTON_ALLOWED_RECIPIENTS env var, and whether a send
needs confirmation.

Output parameters:

- `result` (string)

### `email_allow` (~82 tokens)

Set the recipient allowlist for send_message. Pass specific addresses or globs
(e.g. *@company.com) to restrict sending to them, ["*"] to allow anyone, or [] to
block all sending. A hard ceiling from PROTON_ALLOWED_RECIPIENTS still applies on
top and cannot be loosened here.

Input parameters:

- `recipients` (array, required)

Output parameters:

- `result` (string)

### `set_send_confirmation` (~75 tokens)

Turn the 'confirm before sending' rule on or off. When on, send_message sends
nothing until it is called again with confirm=true, so a person can approve first.
If PROTON_REQUIRE_SEND_CONFIRMATION is set, the rule is forced on and cannot be
turned off here.

Input parameters:

- `required` (boolean, required)

Output parameters:

- `result` (string)

### `calendar` (~25 tokens)

Show the Proton Calendar agenda for the next N days.

Input parameters:

- `days` (integer)

Output parameters:

- `result` (string)

### `contacts` (~28 tokens)

List Proton contacts (name and email), optionally filtered by a query.

Input parameters:

- `query` (string)

Output parameters:

- `result` (string)

### `drive_list` (~32 tokens)

List a Proton Drive folder by path (folders first); empty path is the root.

Input parameters:

- `path` (string)

Output parameters:

- `result` (string)

### `drive_download` (~35 tokens)

Download and decrypt a Proton Drive file to a local directory.

Input parameters:

- `dest_dir` (string)
- `path` (string, required)

Output parameters:

- `result` (string)

### `drive_upload` (~58 tokens)

Encrypt and upload a local file into a Proton Drive folder (empty dest_folder is the root).

Input parameters:

- `dest_folder` (string)
- `local_path` (string, required)
- `mime_type` (string)
- `name` (string)

Output parameters:

- `result` (string)

### `drive_mkdir` (~38 tokens)

Create a new Proton Drive folder (empty parent_folder is the root).

Input parameters:

- `name` (string, required)
- `parent_folder` (string)

Output parameters:

- `result` (string)

### `drive_move` (~41 tokens)

Move a Proton Drive file or folder into another folder (empty dest_folder is the root).

Input parameters:

- `dest_folder` (string, required)
- `path` (string, required)

Output parameters:

- `result` (string)

### `drive_rename` (~34 tokens)

Rename a Proton Drive file or folder in place.

Input parameters:

- `new_name` (string, required)
- `path` (string, required)

Output parameters:

- `result` (string)

### `drive_trash` (~33 tokens)

Move a Proton Drive file or folder to the trash (recoverable in Proton Drive).

Input parameters:

- `path` (string, required)

Output parameters:

- `result` (string)

### `drive_share_link` (~66 tokens)

Create a public share link for a Proton Drive file or folder. The returned URL is
the whole secret (its fragment holds the password) and lets anyone open the file, so
only share it when the person asked to make this file public.

Input parameters:

- `path` (string, required)

Output parameters:

- `result` (string)

### `drive_unshare_link` (~30 tokens)

Revoke a Proton Drive file or folder's public share link.
