qualienai/qualien-mcp

One MCP server that gives your AI assistant a QA toolkit: Playwright, your test files, GitHub, Jira, Postgres and more, behind a single connection.
qualien-mcp is a composite MCP gateway for SDET / QE work. It aggregates Model Context Protocol servers behind one connection, with a curated catalog of 21 testing-relevant servers, per-tool allow/deny, and read-only-by-default guardrails. Add one server to Claude Code, Claude Desktop, Cursor or VS Code instead of five.
bash
npx qualien-mcp
Out of the box it serves the QE starter pair: Playwright MCP (browser automation, DOM, screenshots) and Filesystem MCP (read/edit project files, page objects, test utils), with zero config. Tools are exposed to your assistant namespaced as playwright… and filesystem….
## Why a gateway?
Your assistant can already connect to many MCP servers directly — so a gateway earns its place by doing what a pile of servers can't:
One endpoint to add to any client (Claude Code, Claude Desktop, Cursor, …).
Curation — enable/disable per server and per tool. Fewer, better-named tools = better tool-selection by the model (dumping 200 tools at it makes it worse).
One routing/logging surface — every call is logged to stderr with the downstream, tool, and latency.
Clean lifecycle — spawns each downstream as a child process and tears them all down on exit (no orphaned browser processes).
Curated for QE — an opinionated SDET toolkit, not a generic proxy.
## Use it with your assistant
Claude Code:
bash
claude mcp add qualien -- npx -y qualien-mcp
or in .mcp.json / user settings:
json
"mcpServers": {
"qualien": { "command": "npx", "args": ["-y", "qualien-mcp"] }
Claude Desktop (claudedesktopconfig.json) and Cursor (~/.cursor/mcp.json or .cursor/mcp.json): the same shape under mcpServers.
Claude Desktop extension: download qualien-mcp- .mcpb from the latest release and open it. Claude Desktop asks for a project folder: the Filesystem tools are limited to it, and a qualien-mcp.config.json inside it turns on more servers. Also listed on Smithery.
VS Code (.vscode/mcp.json):
json
"servers": {
"qualien": { "command": "npx", "args": ["-y", "qualien-mcp"] }
That single entry gives your assistant every tool from every aggregated server.
## Add more servers
Drop a qualien-mcp.config.json in your working directory (or pass --config ). Entries merge over the built-in defaults — redefine a key to change it, or set enabled: false to turn a default off. No new release needed.
json
"servers": {
"filesystem": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-filesystem", "/abs/path/to/allow"]
},
"sequential-thinking": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-sequential-thinking"]
},
"chrome-devtools": {
"command": "npx",
"args": ["-y", "chrome-devtools-mcp@latest"]
},
"playwright": {
"command": "npx",
"args": ["-y", "@playwright/mcp@latest"],
"tools": { "deny": ["browserclose"] }
See qualien-mcp.config.example.json for the full shape (command, args, env, enabled, tools.allow / tools.deny).
### Built-in catalog
qualien-mcp ships a curated catalog of 21 known servers (each verified against npm), so you enable one by key with just your secrets — no need to remember packages or commands:
