## 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 2026-10-17.

- **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**: 32/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - License check failed: the license (Proprietary (see LICENSE)) isn't a recognized OSI-approved license.
  - Actively maintained (last published 1 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 44/100
  - 11% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 4803 tokens (~137/item across 35 items; 33 tools + 2 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 73/100
  - Stability observed for 22 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 94/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 78% of tool parameters carry a description.
  - Structured output schemas are declared (45% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - All 3 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 35 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.
  - Supports UI / widget rendering.

**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 mailmcp MCP server?

mailmcp 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, 3779e8e34b137b1aa50f3284ec78710e9ad56bb8c0faa8dcf2eb0d8b277d84bf; the commands to do that are on this page. If it does not match, do not open it.

## MCP tools (33)

### `list_accounts` (~96 tokens)

List mail accounts

Lists the mailboxes: ids, addresses and permitted operations. `backend` "graph" is Outlook (string ids; labels are categories); `reauth_by`: when the owner must sign in to Microsoft again (setup page); `plan`: the mailmcp plan and, near expiry, how to renew. `protection`: verification emails hidden from you.

Input parameters:

- `check_connection` (boolean): Also test every login (slower)

Output parameters:

- `accounts` (array)

### `list_folders` (~61 tokens)

Output parameters:

- `account` (string)
- `folders` (array)

### `search_messages` (~230 tokens)

Search messages

Searches one account, or all with account="all". Gmail: `query` takes Gmail syntax (from:, newer_than:7d, has:attachment, label:); elsewhere full text plus the filters. Newest first, with uid + folder and header hints. Outlook: `total` counts returned results only; `from` is exact.

Input parameters:

- `account` (string, required): "all", or a list_accounts id

Get conversation thread

Lists the conversation of a message across folders (Gmail: All Mail; other IMAP: the folder, INBOX, Sent, Archive; Outlook: whole mailbox), oldest first. `coverage` says what was searched and if it was complete. A thread groups by conversation; it does not prove who replied to whom.

Input parameters:

- `account` (string, required): list_accounts id
- `folder` (string): Default: Gmail All Mail, else INBOX
- `include_bodies` (boolean): Text of the newest 20 (no quotes, 60,000 chars)
