What the publisher says

From the Slideless repository's README, as published. We do not edit it. Read it on GitHub

slideless-mcp

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.

Architecture

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.

Authentication

The 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:

  • OAuth (recommended) — hosts that speak OAuth (Claude Desktop, claude.ai) discover the flow automatically: a no-auth request to /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.
  • Static API key — hosts that support custom headers (Cursor, Claude Code) can send Authorization: Bearer cko_… directly.

Use as a connector

  1. In Claude Desktop / claude.ai / ChatGPT: add a custom connector with URL https://mcp.slideless.ai/mcp.
  2. The host discovers OAuth and opens the Slideless sign-in. Authorize, and you're connected.
  3. (Static-key hosts only) Get a cko_… key at https://app.slideless.ai → Settings → API Keys, and set it as the Authorization header.
