Maple — Claude Code MCP server: review comments inside your agent
Hands a coding agent the review comments pinned to a live preview: it reads the context, edits the code and closes the note with a commit.
claude mcp add --env GITHUB_TOKEN=<GITHUB_TOKEN> --env MAPLE_GITHUB_OWNER=<MAPLE_GITHUB_OWNER> --env MAPLE_GITHUB_REPO=<MAPLE_GITHUB_REPO> --env MAPLE_STORE=<MAPLE_STORE> --transport stdio mcp -- npx -y @maple-kit/mcpWhat Maple does
Maple gathers reviewer notes left on a running frontend, and this server passes them to the agent. The agent waits for a new comment, gets its anchor file:line, viewport, screenshot and the mock it was written under, makes the edit, then resolves the comment against the fixing commit. Reviewers stay in the overlay; both sides meet in the store.
Install the package with npm install @maple-kit/mcp. You get two binaries: maple-mcp for the server and maple-stop-hook, which blocks an agent from declaring itself done while comments remain open. Clients start the server with no arguments, so configuration lives in environment variables. The github store needs GITHUB_TOKEN with read and write access to pull-request comments plus MAPLE_GITHUB_OWNER and MAPLE_GITHUB_REPO. A missing value fails at startup instead of on the first tool call.
With no forge, comments are read from and written to .maple/ in the working directory, which keeps the loop usable on a laptop without a pull request. That store is meant for a local machine, not a preview pod. Every package is 0.x with no compatibility promise, so pin it if the workflow matters to your team. wait_for_comments caps at 55 seconds because clients cut a call at 60, and a timeout counts as a result — agents that treat it as an error stop looping the moment nobody is watching.
What it helps with
- read a review comment together with its file and line anchor
- wait for the next comment instead of polling the page by hand
- resolve a comment and record the commit that fixed it
- run the review loop on a laptop without a pull request
- keep an agent from finishing while comments are still open
Example prompts for the agent
- List the open review comments on branch
feature/cart - Wait for a new comment, then fix what it points at
- Resolve that comment and record the commit sha

Questions about Maple
How do I install Maple in Claude Code?
Run claude mcp add maple -e GITHUB_TOKEN=<GITHUB_TOKEN> -- npx -y @maple-kit/mcp. For the full setup with owner, repo and store: `claude mcp add --env GITHUB_TOKEN=<GITHUB_TOKEN> --env MAPLE_GITHUB_OWNER=<MAPLE_GITHUB_OWNER> --env MAPLE_GITHUB_REPO=<MAPLE_GITHUB_REPO> --env MAPLE_STORE=<MAPLE_STORE> --transport stdio mcp -- npx -y @maple-kit/mcp`.
What does Maple do?
It feeds your agent the review comments collected on a preview deployment and gives it tools to list them, wait for new ones and close them with a commit reference.
Does Maple work without GitHub?
Yes. Leave GITHUB_TOKEN, MAPLE_GITHUB_OWNER and MAPLE_GITHUB_REPO unset and the server uses the comments under .maple/ in its working directory. MAPLE_STORE=file states that explicitly.
