MCP server for Slideless. Wraps the Slideless HTTP API as Model Context Protocol tools so users can list, share, upload, and manage HTML presentations from any MCP host (Claude Desktop, claude.ai, ChatGPT desktop, Cursor, etc.) without installing the slideless CLI.
Hosted on Vercel (Next.js App Router + mcp-handler) at `https://mcp.slideless.ai/mcp`. Listed on the official MCP registry as `ai.slideless/mcp`.
Stateless Next.js route handler — streamable-HTTP transport, no session store. A per-request McpServer is built on each /mcp call and the user's Authorization header is forwarded verbatim to the Slideless Cloud Functions in europe-west1. No database, no secrets to rotate — the user's token never leaves the request.

europe-west1-slideless-ai.cloudfunctions.netThe server is an OAuth 2.1 resource server. It does not host the auth flow itself — it advertises app.slideless.ai as the authorization server and forwards tokens to the Cloud Functions, which validate them. Two header styles are accepted, both forwarded verbatim:
/mcp returns 401 with a WWW-Authenticate header pointing at /.well-known/oauth-protected-resource (RFC 9728), which points at app.slideless.ai. The user signs in / signs up and consents in-browser; no key is ever pasted. New API keys are minted invisibly by the authorization server.Authorization: Bearer cko_… directly.https://mcp.slideless.ai/mcp.cko_… key at https://app.slideless.ai → Settings → API Keys, and set it as the Authorization header.| Tool | What it does |

Pushed to main → Vercel auto-deploys production (project codika/slideless-mcp). Manual deploy:
vercel deploy --prod --scope codikaRate limiting is enforced at the edge by Vercel WAF rules (managed via the vercel firewall CLI), matching path starts-with /mcp:
mcp-per-ip → 60 req / 10s, keyed by IPmcp-per-key → 600 req / 60s, keyed by the Authorization header (so each API key / OAuth token gets its own bucket)Both return 429 when exceeded, before the function runs. Recreate with:

--action rate_limit --rate-limit-window 10 --rate-limit-requests 60 --rate-limit-keys ip --yes
