Quelvio

What is Quelvio?

Quelvio is an MCP server that lets you search your company’s connected knowledge (from Drive, SharePoint, Confluence, Slack, Notion) directly from any AI tool supporting the Model Context Protocol. It is built for enterprise teams who want to query internal documents and conversations through assistants like Claude Desktop, Cursor, or VS Code Copilot.

How to use Quelvio?

Add the server’s URL (https://mcp.quelvio.com/http) to your MCP client’s configuration (JSON file or CLI). On first tool call, your browser opens your organization’s OAuth sign-in page; after signing in, the client resumes automatically. No API key is needed.

Key features of Quelvio

• Search across Drive, SharePoint, Confluence, Slack, and Notion.

Use cases of Quelvio

• Ask an AI assistant “What’s our deployment process for the payments service?” and get a synthesized answer with citations.

FAQ from Quelvio

How do I authenticate to Quelvio?

There is no API key. The first time you invoke a tool, your client redirects you to your organization’s Clerk‑hosted sign‑in page. After signing in, the client reuses the OAuth token (valid ~30 days).

What permissions apply when I query?

Every query is scoped to your individual identity. The server enforces tenant isolation, role‑based feature access (Owner/Admin/Member), and source‑system ACLs (e.g., Google Drive shares, SharePoint groups). You only see what your account would see in those source systems.

What does it cost to use the server?

Tool calls consume Knowledge Tokens (kT): list_domains and get_source_detail are free; query_knowledge costs 1,500 kT (fast), 12,500 kT (standard), or 25,000 kT (deep). These rates are locked at the v0.9 release.

Can I self-host the server?

Yes. The server runs on Cloudflare Workers. Use wrangler to deploy with a TOKEN_ENCRYPTION_KEY and CLERK_SIGN_IN_URL secret. All OAuth artifacts live in Workers KV.

What transport does the server use?

It uses Streamable HTTP (MCP spec 2025‑03‑26). For older clients that don’t support this transport, a stdio bridge is available via the npm package @quelvio/mcp-server.
