## 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.

### 2026-10-16 (score 83, +1)

No change was recorded against any check on this day. Stability & Change Management went from 40 to 43. That category is still filling its 30-day observation window: 12 days of observed history at the previous scan, 13 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (5)

### `list_comments` (~65 tokens)

List review comments

Return the review comments on a branch, newest first.

Input parameters:

- `branch` (string, required): Head branch of the pull request the comments are on, such as `feat/login`. Not a pull request number.
- `statuses` (array): Only these states. Omit for all of them.

### `wait_for_comments` (~114 tokens)

Wait for review comments

Block until a new comment arrives or the wait elapses. Returns status "timeout" rather than failing when nothing arrives.

Input parameters:

- `branch` (string, required): Head branch of the pull request the comments are on, such as `feat/login`. Not a pull request number.
- `cursor` (string): Timestamp from a previous call. Only comments newer than this are returned; omit it to drain everything already there.
- `timeoutMs` (number): How long to wait. Clamped to 55 seconds, under every client's ceiling.

### `resolve_comment` (~57 tokens)

Resolve a review comment

Mark a comment resolved, recording the commit that addressed it.

Input parameters:

- `id` (string, required): The comment's id.
- `note` (string): What you changed, for the reviewer.
- `sha` (string, required): Commit you believe addresses it.

### `get_comment_context` (~96 tokens)

Get a comment's context

Return everything needed to act on one comment: anchor, viewport, surrounding markup and any replay link. A comment written under a Maple Mock carries `mock.recipe` and `mock.replay`, a link to the page in that state.

Input parameters:

- `branch` (string, required): Head branch of the pull request the comments are on, such as `feat/login`. Not a pull request number.
- `id` (string, required): The comment's id.

### `start_solo` (~96 tokens)

Keep a preview's comments on this machine

Start a bridge on localhost and return the link that pairs a deployed preview with it. The reviewer opens the link in their browser and the comments they write there land in .maple/ for list_comments and wait_for_comments to read. They never count toward the merge gate.

Input parameters:

- `previewUrl` (string, required): The deployed preview's URL, such as `https://feat-login.preview.example`. Only that origin is paired with the bridge.

## Common questions

### What is the Maple MCP server?

Maple is an MCP server listed in the public MCP registry as io.github.maple-kit/maple. Review comments pinned to a running frontend, read and resolved by your coding agent. This page covers its npm package (@maple-kit/mcp).

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

Maple scores 83 out of 100 on VerifyMCP. We recorded 1 known advisory against it as of 16 October 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. 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 Maple MCP server expose?

Maple exposes 5 tools: list_comments, wait_for_comments, resolve_comment, get_comment_context, start_solo. Their descriptions and schemas cost roughly 428 tokens of context every time the server is loaded.

### Is the Maple MCP server still maintained?

Maple is still listed as active in the MCP registry. We last reached this channel on 16 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

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

Maple declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
