* feat(mcp): speak spec revision 2026-07-28 (stateless core) Adopt the 2026-07-28 MCP spec revision on the connector endpoint while keeping every handshake-era client (2025-06-18 and earlier) byte-identical: - Accept per-request _meta protocol negotiation (io.modelcontextprotocol/protocolVersion); unsupported versions return UnsupportedProtocolVersionError (-32022) with the supported list. - Implement server/discover (spec MUST): supported revisions, capabilities including the extensions field, identity, instructions, freshness hints. - Decorate results for stateless clients: required resultType, serverInfo in _meta, and CacheableResult ttlMs/cacheScope on tools/list, prompts/list, resources/list, resources/read. - Validate the standard Mcp-Method/Mcp-Name request headers when present (HeaderMismatchError -32020); absence stays accepted. - Declare the ratified MCP Apps extension (io.modelcontextprotocol/ui) in capabilities; the widgets already use the ratified mime type and _meta.ui.resourceUri shape, so no widget changes are needed. - OAuth: include the RFC 9207 iss parameter on every authorization response (success and error) and advertise authorization_response_iss_parameter_supported in RFC 8414 metadata. Resource-not-found already used -32602 and tools/list ordering was already deterministic; both are covered by the new test file. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(mcp): Tasks extension (io.modelcontextprotocol/tasks) Durable handles for long-running MCP tool calls, per the official Tasks extension. A client that declares the extension in its per-request capabilities gets a CreateTaskResult (resultType: "task") immediately; the work completes after the response via after() and lands in the new mcp_tasks table for tasks/get polling. Clients that did not declare the extension are never handed a task (spec MUST). - New mcp_tasks table (migration 20260729094000): company-scoped SELECT RLS, service-role-only writes (mirrors pending_operations), 1-hour expiry, status lifecycle CHECK. pg-real coverage included; triaged as excluded in the full-archive backup contract (transient state). - tasks/get (creator-scoped), tasks/cancel (cooperative, working-only flip), tasks/update (ack no-op: no input_required flows yet). - Tool opt-in via shouldRunAsTask predicate; first producer is gnubok_audit_package, the one genuinely long-running blocking call (multi-minute ZIP generation). estimate_only stays synchronous. - Tool failures complete the task with the standard isError envelope, exactly what the synchronous call would have returned; the failed status stays reserved for infrastructure errors. - server/discover and initialize now advertise the tasks extension. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(mcp): creator-only task RLS, enforced expiry sweep, RoPA entry Compliance-swarm follow-ups on the mcp_tasks migration (editing the migration is safe: it has not shipped beyond the ephemeral PR preview): - SELECT RLS tightened from company-wide to auth.uid() = user_id so the DB grant matches the creator-scoped tasks/get contract; task results carry raw tool output (Art. 5(1)(c)). pg test now proves a same-company colleague cannot read the row. - The 1-hour retention is now enforced, not aspirational: createMcpTask opportunistically deletes expired rows on every creation (idx_mcp_tasks_expires), best-effort (Art. 5(1)(e)). - RoPA entry mcp.async_task_handles added to .compliance/ropa.yaml (Art. 30). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(mcp): literal terminal-update payload for the phantom-column guard The conditional spreads in resolveMcpTask made the payload unresolvable for the no-phantom-columns guard (362 > 360 ceiling). A literal payload writing null for absent terminal fields is equivalent here: the terminal transition sets the complete terminal state.

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.
