What the code does

We read the source, 1 d ago · rules 995398eba69f

A tool parameter reaches a dangerous call

A value the model can set ends up inside a file or shell call. That is not a flaw by itself — for a terminal server it is the job — but it is where things go wrong when it is not.

A tool parameter reaches a file or shell call export_databricks_bundle.outputPath → adapters/mcp/server-stdio.js:724, export_databricks_bundle.outputPath → adapters/mcp/server-stdio.js:716
    fs.writeFileSync(outputPath, result.jsonl);
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.

A tool parameter here reaches a dangerous call

That is not a flaw by itself — but it is where things go wrong when it is not the job. We re-read this code on every release. Watch it and you hear from us the day another one appears.

MCP Memory Gateway — questions

Answers built from our own checks of this server.

Why is there no uptime for MCP Memory Gateway?
MCP Memory Gateway 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 npm package mcp-memory-gateway was installed 164 times last week.
How do I connect MCP Memory Gateway?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls mcp-memory-gateway straight from npm; nothing to host, nothing to sign up for.
How many people use MCP Memory Gateway?
The npm package mcp-memory-gateway was installed 164 times in the last week. Week over week that is -37%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is MCP Memory Gateway open source?
Yes — it is published under the MIT licence, written in JavaScript and 30 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.
