Local-first knowledge graph for token-efficient code review through MCP and CLI
Nothing to run from here
Greenlight is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

What it does
Pre-flight checks for open-source contributions: is this GitHub issue actually landable?
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user greenlight-mcp '--' npx -y @reneturcios/greenlight mcp
# 2 — ask your agent for something these tools do
# check_issue, scan_repo, repo_friction and 30 more
Greenlight costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.
Publisher
Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. This one runs on your machine: your client starts Greenlight as a process under your own user, with your files and your network, so the tool surface below is what it can do to your computer rather than to a server somewhere else. Its scan result is on the Security tab — read the surface before you approve it.
Claude Codedeclared by this listing
This is a public server: you run it yourself and this marketplace is not in the path. You need Node.js — the current LTS (24) is the safe choice; npx comes with it. Claude Code registers it in one command; --scope user makes it available in every project. The '--' is in quotes so that PowerShell passes it on.
claude mcp add --scope user greenlight-mcp '--' npx -y @reneturcios/greenlight mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it runs from its publisher’s own package: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry your client uses to start the process locally. A local server runs with your file system and your network, which is why it is priced without metering.
What you approve
33 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Read from its source code. A server that builds its tool list when it starts can list more tools than this.
Verdict on whether a GitHub issue is actually landable for an outside contributor. Returns GO, RISKY, TAKEN, GATED, or STALE with reasons, claim signals, and detected repo gates. Call this before writing code for an issue.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| issue_url | string | yes | Full GitHub issue URL, e.g. https://github.com/owner/repo/issues/123 |
Rank a repo's open issues by verdict, GO first. Starts with label-tagged good-first-issue / help-wanted issues; when the repo does not use those labels, falls back to the most recent open unassigned issues (flagged as fallback). Use this to pick a winnable issue instead of a taken one.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| repo | string | yes | owner/repo, e.g. PrefectHQ/fastmcp |
Friction score 0-100 for a repo (100 = easiest to land an outside PR). Based on detected contribution gates and computed outcome signals.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| repo | string | yes | owner/repo, e.g. PrefectHQ/fastmcp |
Post a claim comment on a GitHub issue, shaped by the repo's contribution gates. Runs the verdict pipeline first and refuses on TAKEN/STALE verdicts or vouch-gated repos. DRY RUN BY DEFAULT: returns the comment plan without posting unless execute is true, and posting requires GITHUB_TOKEN.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| issue_url | string | yes | Full GitHub issue URL, e.g. https://github.com/owner/repo/issues/123 |
| execute | boolean | no | Post the comment for real. Defaults to false: dry run returns the plan only. |
| force | boolean | no | Claim even on a TAKEN or STALE verdict. |
Prepare to work an issue: check/create your fork and a branch named from the issue title (learning the repo's branch convention from recent PRs when detectable), and write a local PREP.md checklist (verdict, gates, DCO reminders, next commands). Never clones. DRY RUN BY DEFAULT: no fork or branch…
| Parameter | Type | Required | Notes |
|---|---|---|---|
| issue_url | string | yes | Full GitHub issue URL, e.g. https://github.com/owner/repo/issues/123 |
| execute | boolean | no | Actually create the fork/branch. Defaults to false: dry run returns the plan only. |
| dir | string | no | Directory for PREP.md. Defaults to ./greenlight-prep/<repo>-<number>/ |
Open a pull request for an issue from your fork branch. Verifies the branch exists, is ahead of upstream, and (on DCO repos) that every commit carries a Signed-off-by line. Composes the PR title and body (Closes #N plus verdict and gates at open time). DRY RUN BY DEFAULT: returns the composed PR…
| Parameter | Type | Required | Notes |
|---|---|---|---|
| issue_url | string | yes | Full GitHub issue URL, e.g. https://github.com/owner/repo/issues/123 |
| branch | string | yes | Fork branch to open the PR from, e.g. feat/resume-61 |
| execute | boolean | no | Open the PR for real. Defaults to false: dry run returns the plan only. |
| title | string | no | PR title override. Defaults to the branch's latest commit subject or the issue title. |

ATrust score 93 / 100
Release 0.21.0 · scanned 21 Oct 2026
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

| Term | Level | What it prices | Points |
|---|---|---|---|
| capability-exposure | high | capability blast radius (high) — client exposure if the model is manipulated | −6 |

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.

Live transportnot available
Tools were statically extracted from the published source (33 recovered), not enumerated from a running server. Tool-poisoning, Unicode-smuggling, capability and toxic-flow analysis ran on this inferred surface, but a mis-parsed registration could be missed or mis-attributed, so tool-derived findings are capped below “confirmed”. To grade the real runtime surface, scan the running server: --command "npx -y <package>".
Capability — what it could do if the model were manipulated

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.

This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
Release history
Always latest — the install command names no version, so it installs the newest release when it runs; the current release on file is 0.21.0. Pin a release below and the command asks for exactly that one.

no reviews yet
Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish Greenlight can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
