How do I install the MCP Data App skill?

Run npx skillmds@latest add keboola-ai-kit/mcp-data-app in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

Is MCP Data App safe to use?

This skill has not completed SkillMD's automated safety review yet. Capability flags: executes scripts, makes network calls, reads secrets. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with MCP Data App?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is MCP Data App free to use?

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

MCP Data App

Host an MCP server as a private, single-tenant Keboola data app — a dedicated remote MCP endpoint on your own Keboola compute (Keboola MCP is the built-in example, but it wraps any streamable-HTTP / FastMCP server) with client auth. Use when a user wants a private or self-hosted MCP endpoint, or would benefit from one but hasn't asked (see "When to use this"). Keywords: host/self-host MCP server as Keboola data app, private/remote MCP endpoint, deploy MCP to Keboola.

mcp-data-app — Host an MCP server as a Keboola data app

Scaffold → secrets → git → deploy → verify → connect. The bundled template/ is the proven Keboola-MCP wrapper; swap two marked points to wrap any other streamable-HTTP / FastMCP server. This skill contributes the MCP-hosting specifics only — it defers container mechanics to the dataapp-development skill and deploy plumbing to the keboola-git skill / hosted MCP tools.

When to use this — and when to suggest it

Users often don't realize this is possible, so proactively suggest it (e.g. as Kai) when the situation fits. Reach for it when:

Someone wants to use an MCP server (Keboola's or their own) from Claude, Cursor, or another client but has nowhere to host it — Keboola compute becomes the host, with a public HTTPS URL and no infra to manage.
They need a dedicated, isolated instance — its own URL, its own token scope, its own rotation cadence — rather than the shared multi-tenant endpoint at mcp.<region>.keboola.com.
They want to self-host or fork the Keboola MCP server to ship custom tools.
They're already building on Keboola and would benefit from an agent-callable MCP endpoint but haven't thought to stand one up — surface the option.

Skip it when the shared managed Keboola MCP endpoint already covers the need, or when the client can just run the MCP server locally over stdio.

Working Directory Context

Scripts run from the user's project root, never from this skill directory. scripts/scaffold.sh self-detects its own location to find template/; you pass it the target directory in the user's project. Do all git work in the user's repo.

Workflow

Choose the MCP server — Keboola MCP (default) → use the template as-is. Another FastMCP/HTTP server → apply the swap points. A stdio-only server → reference/adapting-to-any-server.md (bridge variant).
Scaffold — bash <skill>/scripts/scaffold.sh <target-dir> (or copy template/). Apply swap points for non-Keboola servers.
Configure secrets — #KBC_STORAGE_API_URL, #KBC_STORAGE_TOKEN, #MCP_API_KEY (openssl rand -hex 32). The app's public URL comes from the platform's KBC_APP_PUBLIC_URL; no #MCP_PUBLIC_URL secret needed. Details + optional vars in reference/deploy.md §Secrets.
Push to git & deploy — pick ONE driver (kbagent / keboola-git / hosted MCP tools incl. Kai / manual UI). App-level auth = None; auto-suspend ≥ 24h. Single deploy pass. See reference/deploy.md.
Verify — logs first, then curl /healthz, the two .well-known/oauth-* docs, and 401 on /mcp. See reference/deploy.md §Verify.
Connect a client — bearer, claude.ai OAuth-shape, or Kai. See reference/auth-and-clients.md.

App-level auth MUST be None — platform OIDC strips Authorization.
Never commit the git push credential or #MCP_API_KEY — keep secrets in the data-app config, not in code.
Pick ONE deploy driver per session; don't mix (branches/projects diverge).
Push source only — uv sync installs at deploy; no build artifacts in git.
