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.

      const forkJson = execSync(`"${GH_CLI}" repo view ${repo.fork} --json name,stargazerCount,updatedAt,url,description `, { encoding: 'utf-8', timeout: 15000, stdio: ['pipe', 'pipe', 'pipe'] });
        self._process = subprocess.Popen(

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 sdk -- npx -y @mnemopay/sdk
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "sdk": {
      "args": [
        "-y",
        "@mnemopay/sdk"
      ],
      "command": "npx"
    }

This one needs environment variables set before it will start: MNEMOPAY_API_KEY (MnemoPay API key from https://mnemopay.com/dashboard), MNEMOPAY_PERSIST_DIR (Directory where the local ledger + memory store persist (default: ~/.mnemopay)). The author declared them in the registry entry; get the values from the project itself.

SDK — questions

Answers built from our own checks of this server.

Why is there no uptime for SDK?
SDK 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 @mnemopay/sdk was installed 119 times last week.
How do I connect SDK?
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 @mnemopay/sdk straight from npm; nothing to host, nothing to sign up for.
How many people use SDK?
The npm package @mnemopay/sdk was installed 119 times in the last week. Week over week that is -51%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is SDK open source?
Yes — it is published under the Apache-2.0 licence, written in TypeScript, 8 stars on GitHub and 2 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
