* feat(mcp): lazy authentication so a client can connect before an account exists Second PR of agent-first onboarding (#1814). A client with no token may now initialize, list the default catalog and call the three documentation tools (search_tools, list_skills, load_skill). Every other request keeps the transport-level 401 + WWW-Authenticate, which is what Claude, Claude Code and Codex turn into their Connect prompt; with #1855 the account is created inside that prompt, so the first protected tool call is the whole signup trigger. - The JSON-RPC body is parsed before auth so the method and tool name can decide whether a token is required. A tokenless unparseable body keeps the old 401 answer. - Anonymous callers get an 'anonymous' actor, an empty scope set, a not-connected variant of the initialize instructions, and the full default catalog from tools/list (the agent has to be able to name a protected tool to trigger the challenge). - Anonymous traffic is rate-limited per truncated IP via checkRateLimit; truncateIp moves to lib/api/ip.ts so the MCP server can use it without importing the v1 wrapper (which pulls lib/init and would cycle). - gnubok_list_skills is now company-independent and skips its two context lookups when there is no company (anonymous or not yet onboarded).

Optional- company tools now advertise company_id and resolve (membership-checked) it when an authenticated caller names one; anonymous callers cannot.

Accounted
Open-source Swedish accounting software for sole traders (enskild firma) and limited companies (aktiebolag). Double-entry bookkeeping that complies with Swedish accounting law, built to be operated by you or by your AI agent.
Website · Hosted app · Documentation
Why Accounted?
Compliant by construction. Accounted implements double-entry bookkeeping under Swedish accounting law (Bokföringslagen). Voucher immutability, sequential voucher numbering, period locks, and 7-year document retention are enforced by database triggers, not by convention. Corrections are made the legal way, with reversal entries (storno), never by editing history. See ARCHITECTURE.md for how.
Agent-native. The full bookkeeping engine is exposed as 100+ MCP (Model Context Protocol) tools with scoped API keys, so an AI agent can do the books in Accounted: categorize transactions, draft vouchers, reconcile periods, and prepare declarations. Posting is staged for human approval, so the agent proposes and you decide.
Yours to run. AGPL-3.0 licensed and fully self-hostable with Docker and Supabase. Use the hosted version at app.gnubok.se or run your own.

Self-Hosting
git clone https://github.com/erp-mafia/accounted.git
cd accounted
./setup.sh # Prompts for Supabase credentials, generates .env
docker compose up -d
You need a Supabase project and must apply the database migrations before first use. See docs/SELF-HOSTING.md for the full step-by-step guide, including Supabase setup, auth configuration, optional features (AI, email, push notifications), and troubleshooting.
Development Setup
