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.

Runs an external command [пакет] tools/github.js:164, packages/catalyst-core/mcp_v2/tools/github.js:200, packages/catalyst-core/src/native/setupServer.js:10 и ещё 7
        return execSync(command, {
Touches key and credential files [пакет] tools/github.js:646, packages/catalyst-core/mcp_v2/tools/github.js:686

In the project's build, not in the package

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

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 mcp -- npx -y catalyst-mcp

{
  "mcpServers": {
    "mcp": {
      "command": "npx",

    }
  }

Optional settings from the registry entry, left out of the block above: GITHUB_TOKEN (GitHub token used only by the create_github_issue tool. Optional — falls back to `gh auth token` if unset. Not required for any other tool).

Mayankmahavar1mg — questions

Answers built from our own checks of this server.

Why is there no uptime for Mayankmahavar1mg?
Mayankmahavar1mg 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 catalyst-mcp was installed 89 times last week.
How do I connect Mayankmahavar1mg?
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 catalyst-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Mayankmahavar1mg?
The npm package catalyst-mcp was installed 89 times in the last week. Week over week that is +97%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Mayankmahavar1mg open source?
Yes — it is published under the MIT licence, written in JavaScript, 93 stars on GitHub and 76 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
