caveauDbnAgent — n8n starter workflow

A clonable n8n agent that drives the Do Better Norge legal tools over MCP. One MCP Client Tool node connects to the DBN bridge and enumerates the whole catalog automatically (currently 23 dbn.* tools) — the catalog is dynamic (includes/DbnMcpRuntime.php::tools()), so new tools appear without editing this workflow.

What's in caveauDbnAgent.json

When chat message received ─▶ DBN Agent (AI Agent)
                                 ├─ ai_languageModel ◀─ Chat Model (placeholder)
                                 └─ ai_tool          ◀─ DBN MCP Tools

• DBN Agent — system prompt steers the default chain dbn.search_legal → dbn.legal_analysis → dbn.korrespond and enforces the process-and-forget privacy rule (never auto-saves; suggests dbn.redact).
• DBN MCP Tools — MCP Client Tool node, httpStreamable transport, https://mcp.dobetternorge.no/mcp, Bearer auth, include: all.
• Chat Model — a placeholder lmChatOpenAi node. No cloud spend is wired by the template — you attach your own credential.

Import + wire it up (Dave's step — no n8n API access from here)

1. n8n → Workflows → Import from File → pick caveauDbnAgent.json.
2. Mint a DBN MCP token: log in at https://tools.dobetternorge.no/mcp.php, create a user token (looks like dbn_user_mcp_...). Copy it once.
3. DBN MCP Tools node → Credential → Bearer Auth: paste the token as the bearer value. (The node sends Authorization: Bearer dbn_user_mcp_....)
4. Chat Model node → Credential: attach your existing OpenAI-compatible credential — e.g. the colin LiteLLM proxy (http://10.0.1.10:4000, base-URL override on an OpenAI cred) or Azure OpenAI. Set the model to one your key can serve (e.g. gpt-4o).
5. Open the chat (the trigger node's built-in chat) and ask, e.g.: "Min sønn ble akuttplassert av barnevernet. Hva er fristene og hvilke rettigheter har jeg?" The agent should call dbn.search_legal / dbn.legal_analysis and answer with cited sources.

Notes

• The DBN tools require an active DBN member session behind the token; the token carries the user/tenant + scopes. Keep the token secret (vault it; don't commit).
• If the MCP node lists zero tools, re-check the bearer token and that the bridge (mcp.dobetternorge.no, caveau-mcp container dobetternorge-mcp:3002 on colin) is up.
• This starter matches the live catalog as of 2026-06-21. Re-export from n8n if you customize it so the repo copy stays current.
