### Install and Run Superargs

Source: https://github.com/supercorp-ai/superargs/blob/main/README.md

Installs and runs Superargs using npx, specifying an MCP server command with arguments to be replaced at runtime. The `--stdio` flag indicates the command for a stdio MCP server.

```bash
npx -y superargs --stdio "npx -y @modelcontextprotocol/server-postgres {{databaseUrl}}"
```

### Superargs with SQLite MCP Server

Source: https://github.com/supercorp-ai/superargs/blob/main/README.md

An example of using Superargs with the SQLite MCP server, where the database path is provided as a runtime argument using the {{dbPath}} placeholder.

```bash
npx -y superargs --stdio "uv mcp-server-sqlite --db-path={{dbPath}}"
```

--------------------------------

### Superargs: Dynamic Argument Replacement

Source: https://github.com/supercorp-ai/superargs/blob/main/README.md

Demonstrates how Superargs replaces argument placeholders (e.g., {{githubToken}}) in the MCP server command with values provided at runtime. This is useful for sensitive information like API keys.

```bash
npx -y superargs --stdio "GITHUB_PERSONAL_ACCESS_TOKEN={{githubToken}} npx -y @modelcontextprotocol/server-github"
```

--------------------------------

### Run MCP Inspector with Superargs

Source: https://github.com/supercorp-ai/superargs/blob/main/README.md

Connects Superargs to MCP Inspector by running Superargs within the MCP Inspector command. This allows managing MCP servers, like PostgreSQL, through the Inspector's interface.

```bash
npx @modelcontextprotocol/inspector npx -y superargs --stdio "npx -y @modelcontextprotocol/server-postgres {{databaseUrl}}"
```
