What it does

Simpler.Asia is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.

From the publisher's description, Electra Index matched it to one capability: invoicing. That makes it a candidate for tasks such as send and chase invoices.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence) and are not a test of the tool.

318 tools offered to AI assistants

  • simpler.directory · DISCOVERY TIER 1 of 3 — the service directory: one token-dense line per service (s:name st:status cost:class ops:N — purpose). START HERE instead of reading every tool. No auth required. NEXT: simpler.describe_service with a service name fr
  • simpler.describe_service · DISCOVERY TIER 2 of 3 — one service's operations and entity shapes from the live catalog, token-dense (op lines name the underlying tool). No auth required. NEXT: simpler.invoke {service, operation, args} — or call the named tool directly.
  • simpler.invoke · DISCOVERY TIER 3 of 3 — execute one operation: dispatches to the underlying generated tool (same gates, same envelope, same idempotency as calling it directly). Requires auth. args = the underlying tool's arguments object.
  • simpler.outcomes · DISCOVERY TIER 0 — the OUTCOME MENU: one line per common business outcome, each mapped to ONE tool with one-call notes (composites: ONE call creates the whole document). START HERE for a business task. No auth required. NEXT: call the named

  • agent_note_send_cross_tenant · Send a cross-tenant AI-to-AI message into another tenant's agent_note inbox — the door that turns a cross_tenant_comm consent grant into an actual reach. Both tenants must be KYB-approved and the recipient must hold an active grant (claims

  • expense_create · Logs a new expense — amount_cents must be integer CENTS (a decimal string via `amount` also works, and `category` resolves to a category_id by name). A same-amount, same-UTC-day duplicate for the same user is refused as CONFLICT unless you
  • expense_submit · Sends your own draft expense into the approval queue — draft only; an already-submitted or resolved expense refuses CONFLICT, and only the expense's own creator may submit it. Nobody is notified automatically — approvers see it appear in th
  • expense_approve · Approves a submitted expense claim — requires the admin or owner role, and only a 'pending' expense qualifies (CONFLICT otherwise). Stamps approved_by and approved_at with the caller and the current time; once approved, the row's content fr
  • interaction_create · Log an interaction — call, meeting, email, message, visit, payment, or other — against a contact. The ONE activity-logging door every lane funnels through, so the contact's last_contact_at freshness bumps no matter which surface logged the

  • invoice_adjustment_record · [REQUIRES APPROVAL] Records a credit note, write-off or post-issue discount on an issued invoice. A credit_note is numbered from the credit note series, holds its tax at the invoice's rate and takes reason_code and credit_outcome: reduce_ba
  • invoice_payment_record · Records a money-in fact row against an invoice (by invoice_id or its invoice_number) in ONE call: money is integer CENTS via amount_cents, or a decimal STRING via amount — never multiply or divide yourself. A draft invoice auto-advances to

  • myinvois_invoice_record_submission · Record the UUID the LHDN MyInvois portal assigned after the owner keyed this e-invoice into the portal (its form or LHDN's Excel batch template). Simpler never submits to LHDN and never calls the MyInvois API; this only stores the UUID the

  • quote_convert · Converts a quote into its invoice in ONE call: claims the quote's 'converted' status first (so a lost race never creates an orphan invoice), copies every live line item across, and records converted_invoice_id — nothing else to do afterward
  • settlement_proposal_propose_cross_tenant · Record a payment obligation against a KYB-verified partner tenant's settlement_proposals — the record-don't-move on-ramp: this writes the row only, no money moves until a later settlement-rails door executes it. amount_cents is a nonzero in
  • sticky_note_create · Create a sticky_note.
  • stock_item_adjust · Move stock in or out by id or item name, in one atomic write with its movements-ledger row: stock-out clamps at zero (never negative) and applied_quantity reports what actually moved. An unmatched name CREATES the item at quantity 0 first s
  • team_assignment_create · [REQUIRES APPROVAL] Delegates a task to a teammate (or yourself) as a new team_assignment; status is workflow-owned and always starts 'pending' — passing status yourself fails validation instead of being silently overridden. Accepts natural
  • workflow_create · Create a workflow — an AI operator's job: validates definition_json (a { nodes, edges, schedule? } graph) against the platform's node vocabulary, refusing unknown node types and any comms/message-shaped step that isn't a prepare_output node
  • workflow_prepared_outputs · List this tenant's APPROVED prepared outputs: drafts a workflow's prepare_output nodes parked for review, which a human then approved in the platform inbox. Pending and rejected drafts never appear here — approval happens only in the inbox,
  • ai.budget · Your prepaid wallet, period spend, caps, and runway as a compact line DSL (~8 lines). Requires auth (your balance is closed data). Read this BEFORE committing paid actions; pair with ai.estimate_cost to price a specific call first.

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
