Install in your client

Paste into the AI you're chatting with — it will figure out the rest

Please install the `gst-validator-mcp` MCP server into my current AI client (that's you).

Required prerequisites (do these first if not already done):
- **Install Node.js and npm** — Required to run the published MCP launcher via npx. (https://nodejs.org/)

Optional prerequisites:
- Optional API key for paid tiers — You can use the server anonymously on the free tier up to 100 calls/month/IP. For paid tiers or authenticated access, obtain an API key from the hosted upgrade page. (https://gst-validator-mcp.atlasword.workers.dev/upgrade?tier=solo)

Canonical MCP server config (stdio transport):
- command: `npx`
- args: ["-y","@insnapsprakhar/gst-validator-mcp"]

Note: Preferred install path is the published npm launcher, which wraps mcp-remote and connects to the hosted endpoint automatically. The README also shows a direct mcp-remote invocation against https://gst-validator-mcp.atlasword.workers.dev/mcp with an Authorization header, but the npm launcher is the simplest portable option. Anonymous free-tier access is supported; if you need paid-tier features or authenticated usage, use an API key in the launcher flow if supported by the package or connect directly with mcp-remote and an Authorization: Bearer <your-api-key> header.

Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.
