Connect Gemini to your books.
Solid Accounting’s local gateway lets Gemini enter, categorize, and answer questions — every change attributed, reversible, and waiting for your approval.
Gemini CLI via MCP · Professional and up · You approve writes
Hand off the busywork. Keep the control.
Gemini works in a real double-entry ledger through the gateway. It proposes; you approve. Nothing posts behind your back.
- Automate data entry“Enter these 30 receipts” — it drafts balanced journal entries from your description or a file, ready for you to approve.
- Categorize in bulkHand it a pile of imported transactions; it proposes accounts with confidence and flags the uncertain ones.
- Answer questions about the books“What did I spend on contractors last quarter?” — it queries the ledger and answers, with the entries behind it.
- Help close the monthDraft reconciliations, surface anomalies, and prep adjusting entries — you review and post.
Connect through MCP — a few clicks, or a few lines
Solid Accounting exposes your books as a local MCP server, so the Gemini tools you already use connect to it directly. Connecting your own AI assistant and the local API need the Professional or Accountant tier.
Turn on the gateway
Enable the local AI gateway in Solid Accounting and issue a scoped key. It listens on your computer only — nothing is exposed to the internet.
Add Solid Accounting in Gemini CLI
Add Solid Accounting to ~/.gemini/settings.json under mcpServers (a local stdio command), and the Gemini CLI can work in your books.
Gemini works through the guarded gateway
Every request runs under the same capability tiers, attribution, and audit trail, so you can give it real reach and still undo anything.
Prefer to script it? The same thing is a plain local REST API:
# Point any agent at your books — the manifest tells it how GET http://127.0.0.1:21384/api/v1/agents.md # Every write carries who/what/why — and groups for one-click undo POST /api/v1/journal-entries/batch-categorize X-API-Key: sk_live_••••• X-Actor-Reason: Recategorized June expenses per user X-Actor-Session: claude-2026-06-13 → 200 { data: { updated: 12 } } # logged · reversible · tier 1 # Tried to touch a closed period? The gateway refuses — by construction. → 409 { error: { code: PERIOD_CLOSED } }

Give Gemini real reach — without handing over the keys
Every change your own AI assistant makes goes through one guarded path. The accounting rules can’t be talked around.
- It can’t unbalance your books. Every posted entry must balance — the gateway rejects anything that doesn’t.
- It can’t touch a closed period. Writes dated inside a locked period are refused, not negotiated.
- Every change is attributed and can be undone. AI writes are grouped per session for one-click undo, and the hash-chained audit trail records who, what, and when.
- Reach is capped by tier. A credential can read, or make reversible edits; high-stakes actions wait for your approval.
- Unattended runs can wait for review. Route an agent’s work to a review queue so a person signs off before it posts.
- Nothing is sent on your behalf. It can propose reconciliations and draft reminders; completing a reconciliation or sending anything stays a human act.
Higher tiers don’t run autonomously — they ask you first.
