Simpler MCP server

• Registry nameasia.simpler/simpler-asiaverified in the MCP registry

The registry name sits under simpler.asia. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-29 the server answered initialize and tools/list without a sign-in. First answer in 3740 ms.

• Its tools do prepare invoices, receipts and payment chase-ups for approval, but not check rent and footfall before signing a lease.
• Checked on 5 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• 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…

• 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…

• simpler.approval_status

  Check a parked approval by approval_id (returned in an APPROVAL_REQUIRED refusal). States: pending (the account owner has not decided — tell the user, do NOT retry the original call), executed (done — the result rides this response; never…

• 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…

• contact_upsert

  Create-or-merge a contact keyed on email-then-phone identity — the sync door the future desktop harness and ingest lanes write through. Matching probes email first, then phone; a hit MERGES only the fields you send (omitted fields keep…

• 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…

• 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…

• 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…

• 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…

• invoice_create

  ONE call creates the whole document: claims the next invoice number, then writes the header plus every line in `items` ([{description, quantity, unit_price_cents}], integer CENTS). client_name finds a client by name or creates one. Birth…

• 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…

• 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…

• myinvois_invoice_generate

  Mint a sealed LHDN e-invoice in ONE call: invoice_type, line_items (unit_price_cents in integer CENTS, tax_rate_bps in basis points), and a buyer as customer_id or an inline buyer object. Refuses until myinvois_settings_save is done…

• 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…

• myinvois_invoice_read

  Read one sealed e-invoice by id, with its portal_field_sheet: the document's values laid out to key into the LHDN MyInvois portal form (e-invoice details, supplier, buyer, each line, totals), coded values with their meaning. Simpler never…

• quote_create

  ONE call creates the whole document: claims the next atomic quote number, then writes the header plus every line in `items` ([{description, quantity, unit_price_cents}], integer CENTS) together. client_name resolves an existing client by…

• 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…

• 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…

• 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…

• 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…

• 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…

• 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…

• 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.

• ai.estimate_cost

  Price an AI task BEFORE running it: provider passthrough at wholesale cost, no markup — the per-token platform fee is retired, so text/reasoning passes through at cost. Anonymous — open catalog includes open pricing. Returns integer…

• sales_receivables

  Who owes you, by client: each client's unpaid balance aged by days past its due date — current (not yet due), 1-30, 31-60, 61-90 and over 90 days — counted in the business's own days (the sales_settings time zone), so an invoice due today…

• sales_document_show

  Show one invoice, quote or receipt as the document itself. When the result has a second content block, it is the document as copy-ready plain text (title, business, billed to, dates, one line per item, the totals as printed, notes…

• invoice_message_prepare

  Prepare what a business sends a client about one issued invoice: purpose 'invoice', 'reminder' (overdue), 'receipt' (paid in full) or 'promise_follow_up' (promised date passed); left out, the one that fits. language 'en', 'ms' or 'zh'…

• invoice_reminders_due

  Today's collection list, in the business's days (its sales_settings time zone). reminders: each issued invoice still owed that is 3 days before its due date, on it, or 7 or 14 days after, as its client's reminder_cadence allows (standard…

• statement_prepare

  A client's statement of account over a period of the business's own days (the sales_settings time zone): the balance they owed before it (opening), each invoice issued, payment received, credit and write-off in it with a running balance…

• invoice_handoff

  Get one issued invoice ready to give the client, in one call: the document, the client link (made if it has none), the PDF (printed or the stored one) and the prepared message (invoice_message_prepare's words, with the link). ready lists…

• forecast.run

  WHAT-IF / scenario lane: runs monthly data YOU supply through a seeded 5,000-path simulation of monthly revenue and costs; bands are simulation outputs, not calibrated probabilities. The paths are clustered into 3-7 outcome bands for the…

• forecast.run_stored

  Run the tenant's REAL forecast from the books — cash receipts (recorded invoice payments by payment date, plus paid invoices with no recorded payment at their paid date, flagged) and expenses by expense date, monthly in the tenant's base…

• forecast.read

  Read the tenant's STORED forecast — the verify-read for this rail. view picks the answer, one of summary, monthly, variance, scenarios, weekly (default summary). summary: the outcome bands (label, growth_direction, probability_pct…

• image.generate

• document.extract

  Fetch a document from a URL, classify its type (personal/medical/business/unknown) with keyword + PII-pattern heuristics (documents containing actual PII data are NEVER business), and return extracted text capped at 100K chars. Free…

• spreadsheet.create_with_content

  Create a spreadsheet in the user's library from CSV content in ONE call: the platform stores the bytes (honest text/csv) and registers the file row. Free — storage costs nothing; only AI lanes bill. Returns the file row including its id…

• agent_note_mark_read

  Confirm receipt of a note in your cross-tenant agent_note inbox — the ONLY edit a recipient holds, moving status unread to read under the registry's transition guard. Idempotent: re-confirming an already-read note is a no-op, and the…

• contact_create

  Create a contact and, in the same call, log its first note and/or first interaction — the composite first-touch door. Children validate before the contact write; if the contact commits but a child then fails, the error names the contact's…

  Search your contact rows by text.

• contact_note_create

  Add a note to a contact — the same door as the granular tool, extended only to accept contact_name, contact_email or contact_phone in place of contact_id. A name match must be unique: more than one hit refuses, listing the candidate ids…

  List your contact_note rows (newest first).

• contact_note_read

  Read one contact_note by id.

• contact_note_delete

  Delete a contact_note you own.

• desk_surface_create

  Pins one widget or a saved artifact onto the operator's home canvas. kind='widget' requires widget_key from the shipped enum; kind='artifact' requires content_ref (an assistant artifact id) — the door enforces whichever pair the kind…

• desk_surface_update

  Moves, resizes, or restacks a surface already on the desk canvas — x/y/w/h/z_index are real column writes, not a layout cache. The surface's identity is frozen here: kind, widget_key, and content_ref never change through this door, only…
