korean-law-mcp runs. An Argusic agent installed it in 1.5 minutes and hit no errors on a clean machine with no GPU, and the whole session was recorded.
Korean Law MCP server v4.14.2 builds, all 989 tests pass, STDIO and HTTP modes run correctly with MCP protocol, CLI reports version, 10 tools registered via tools/list
What the agent ended up with on a clean machine, in its own words. How this is measured
Measured by Argusic on a fresh machine every time. Every number links to its evidence. Argusic Score 100 of 100 (the mean of this project's run scores).
At a glance
Subject data from GitHub, linked at the top of this page, refreshed . Test data by Argusic (CC BY 4.0); every number links to a run page with the full log, the recording, and their sha256 hashes.
What was measured
From the run that decided this verdict. Every line is a recorded value, not an estimate.
- Install time
- 2 minutes
- Cold machine to finish
- 3 minutes
- Errors hit and fixed
- 0 hit, 0 fixed with no human help
- How the result was proved
- npm test exited 0, 989 passed across 108 files; MCP STDIO initialize returned capabilities; HTTP /health returned 200; tools/list returned 10 tools; CLI --version returned 4.14.2
- Model tokens used
- 27,793
- Exact commit tested
- efbf82ca1bc3
- Container image
- sha256:cdd920bce783
What was not measured
The other half, so you can see exactly how far this evidence goes. A gap is printed as a gap and never filled in.
- Peak GPU memory
- this ran on a CPU machine, so there was no GPU to sample
- Behaviour over a long run
- each attempt uses the smallest documented settings and a fixed time budget, so this measures whether it runs, not how it holds up under load

The entire project works out of the box — no errors to fix. Here's the summary:
- **Node.js v22.12.0** was installed via nvm (container had v18.19.1, project requires >= 20.19.0)
- **`npm ci --ignore-scripts`** installed 240 packages (no errors)
- **`npm run build`** (tsc) compiled cleanly (no errors)
- **`npm test`**: 108 test files, 989 tests, all passed
- **STDIO mode**: MCP initialize returned `{"serverInfo":{"name":"korean-law","version":"4.14.2"},"…
- **HTTP mode**: server started, `/health` returned HTTP 200, `/mcp` with `tools/list` returned 10 …
- **CLI**: `node build/cli.js --version` returned `4.14.2`Replay the whole session, every command from a clean machine to this point.
How it was tested
One agent, one container, no human help. It installs the project the way its own documentation says to, runs it, and fixes what breaks. Everything below is recorded as it happened: the terminal session, the log and the exact commit. The full method.
Strengths and limits
Measured facts, not opinions. How this is written.
What went well
- Reached a running state on a clean machine, with the session recorded.
- Installed in 1.5 minutes.
- Nothing broke on the way: zero errors between clone and running.
- Ran without a GPU, so it does not need one to start.
- Licensed MIT, as reported by its host.
What did not, or is not known
- Measured once so far. A single attempt shows it can run, not that it runs reliably.
What it is a reasonable choice for
- Trying it on a laptop or a small server: it reached a running state without a GPU.
- A quick evaluation: it was running 1.5 minutes after the clone.
- Following its own README: the documented path worked with nothing to fix.
Also tested, in the same area
Every one of these was installed and run by Argusic on a clean machine. Nothing appears here that was not tested.

[](https://argusic.com/subject/korean-law-mcp)Questions
- Does korean-law-mcp run?
- Yes. korean-law-mcp runs. Argusic installed and launched it on a clean machine in 2 minutes, hitting 0 errors on the way, and recorded the session.
- How did Argusic test korean-law-mcp?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit efbf82ca1bc3. One attempt is recorded, and the full method is on the methodology page.
- What did it cost to test korean-law-mcp?
- The run that produced this verdict cost $0.01: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does korean-law-mcp take to install?
- 1.5 minutes in the run that decided this verdict, from a clean machine to a running state. That is one measured attempt, not an average.
- Does korean-law-mcp need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing korean-law-mcp?
- Nothing did, in the recorded run: zero errors between clone and running.
- Where is the evidence for korean-law-mcp?
- The recorded run is on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
