TL;DR

• Remote setup is a URL plus your API key — no install.
• Local clients use npx -y @plugsky/mcp.
• OAuth 2.1 + DCR supported for connectors that require it.
• 20 tools cover search, transcripts, audio, vision, image, memory, browsing, code and RAG.
• Free tier available for evaluation; paid plans are fair-use.

Remote setup, step by step

1. Create an API key in Dashboard → API Keys.
2. In your MCP client, add a remote server named plugsky with URL https://plugsky.com/mcp and header Authorization: Bearer YOUR_KEY.
3. Run the client's tool discovery — you should see 20 tools, 12 prompts and 10 resources.
4. Ask the model to call plugsky_models to confirm the connection.

OAuth 2.1 and dynamic client registration

Connectors that require OAuth discover the authorization server at /.well-known/oauth-authorization-server, register dynamically at POST /oauth/register, then complete a PKCE authorization-code flow. Tokens are regular Plugsky API keys, scoped to mcp.read, mcp.write or full mcp access — enforced per tool.

What the 20 tools cover

Chat with 36+ model aliases behind a 7-tier provider failover; search the web (single and fused multi-engine); fetch or ground pages; pull YouTube and video captions; transcribe audio with Whisper; describe screens and generate images with FLUX; save and search persistent memory; fuse your knowledge store; browse JS-heavy pages with headless Chromium and persistent sessions; run sandboxed Python; and ingest sites into memory.

Frequently asked questions

Is Plugsky MCP free to try?

Yes — the free plan includes two models and 500 requests/day; a 14-day trial unlocks everything.

Does it work in ChatGPT?

Yes, via Connectors with developer mode: add https://plugsky.com/mcp and your key (OAuth supported for Business/Enterprise).

Can I limit which tools a key can use?

Yes. OAuth-scoped keys (mcp.read / mcp.write) are enforced per tool; local installs can narrow groups with --groups.

Where is usage metered?

Every tool call is metered per user — see Dashboard → Usage & Analytics.
