Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

            raw = subprocess.run(

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add n3fjp-mcp -- uvx n3fjp-mcp
~/Library/Application Support/Claude/claude_desktop_config.json

This one needs environment variables set before it will start: N3FJP_HOST (N3FJP API host.), N3FJP_PORT (N3FJP API port (Settings → Application Program Interface). Default 1100. Not the multi-PC networking port.), N3FJP_TIMEOUT (Seconds to wait for an N3FJP response.), N3FJP_ALLOW_DB_WIPE (DANGER. When off (default), raw SQL that could delete/overwrite the entire log (DROP/TRUNCATE, unscoped DELETE/UPDATE) is refused. Only enable with a backup and full understanding of the risk.). The author declared them in the registry entry; get the values from the project itself.

N3fjp MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for N3fjp MCP?
N3fjp MCP runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package n3fjp-mcp was installed 53 times last week.
How do I connect N3fjp MCP?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls n3fjp-mcp straight from pypi; nothing to host, nothing to sign up for.
How many people use N3fjp MCP?
The pypi package n3fjp-mcp was installed 53 times in the last week. Week over week that is -18%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is N3fjp MCP open source?
Yes — it is published under the MIT licence, written in Python and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
