47 MCP servers for Claude, for freelancers and small businesses

Loan and lease schedules from the terms of the agreement

the level payment, the effective annual rate beside the nominal one, and every period's opening balance, interest, principal and closing balance in integer minor units. Compounding and payment frequency are two different clocks, so the periodic rate is always the equivalent rate taken through the compounding clock. It posts nothing and stores no schedule.

A fixed asset register that depreciates on the rates the tax authorities publish

the Polish KST annex rates from the CIT and PIT acts, the UK capital allowance pools with the annual investment allowance, and the US MACRS GDS half-year tables for 3, 5 and 7 year property. The tables are bundled files rather than a feed, and the annex positions that could not be stated with confidence are refused by name rather than guessed.

Backlink checks from Claude or Cursor

does a page link to your domain, dofollow or nofollow, anchor text, HTTP status, robots guards. Nothing stored.

Bank CSV exports categorised by your rules, monthly summaries per currency, reconciled against your expenses, subscriptions detected.

QR codes and barcodes from chat

SEPA payment QR for an invoice, vCard, WiFi, Code128, EAN-13 and UPC-A as SVG or PNG.

Bills of sale for equipment, vehicles and stock, kept the way the signed paper is kept

parties, the item with its VIN, serial number or IMEI where it has one, the price and the date, an as-is clause and any warranty in the seller's own words, and signature lines for both sides. Work as a draft, finalize into the frozen signing copy, and render Markdown or a single self-contained HTML file that prints to PDF from any browser. Drafts render with a DRAFT watermark, a byte-identical repeat sale is refused with the id already stored, and a finalized document needs confirm_finalized to delete, with the BOS number never reissued. Currencies are never added together and no total is stored.

Credit notes and purchase orders on the same engine as your invoices

the VAT unwound at the rate you charged, and never more credited than the invoice billed.

Read .ics calendars and feeds

events in a window, free and busy, conflicts, exports, and meetings turned into billable time entries.

One double-entry ledger over the books you already keep

invoices, credit notes, deposits, expenses, the bank import and the fixed asset register. Every line carries the server, the document id and the date it came from, and the trial balance is proved to the minor unit. It writes into none of those books, and there is no way to type an entry into it.

One price list and one labour rate card, kept where the invoice and the quote servers can both read them.

A SKU carries a code, a unit, an optional VAT rate and price ROWS with valid-from dates, so the price on a date is worked out on the call and raising a price in July does not rewrite what June was quoted at. lines_resolve hands back the same lines already priced, in the invoice_create argument shape and in the quote_create argument shape at once. Nothing is invented: an unknown code is refused by name.

Change orders against a quote or a work order, kept the way a variation is kept on site

added, removed and changed lines with a quantity, a unit price in minor units, a reason and a date; a status that moves draft to sent to approved or rejected with every step dated; the running contract value as the original plus approved deltas, with pending deltas held apart; and the approved delta as invoice_create-ready items in major units and quote_create-ready items in minor units at once. No delta is stored: value and VAT are derived from the lines on every call.

Checklists you build once and run many times, and the dated record of each run that somebody signs.

A run COPIES its checklist's steps when it starts and records the version it copied, so editing the checklist afterwards never rewrites a run already under way and deleting the checklist leaves its runs readable. Each step is marked pass, fail or not applicable, with who marked it, on what day, and a note. Not applicable counts as ANSWERED and never as passed. A required step unanswered or failed blocks the signature; force signs anyway and the exceptions stay on the record and print on the report. No count is stored: every figure is derived on the call.

A personal library of contract and proposal clauses with a 25-clause starter set, variables, search, and assembly into Word or markdown.

Credit notes against an invoice or standalone

recipient, reason, line items with quantity, unit price and tax rate, and currency. Every note starts as a draft with a draft id no client sees; finalizing burns the final CN-YYYY-NNNN number in the issue date's year and freezes it, with the counter written before the record so a crash burns a number rather than reusing one, and the final series never has a gap. The line math is round half-up per line then sum, so the printed document reproduces on a calculator and a total can never drift from the printed lines. Renders are Markdown to paste into an email or a self-contained printable HTML page, and the summary totals what was credited per currency, reason and month.

Currency converter on the European Central Bank reference rates

latest, history, any-date, and fx_rates ready for rebilling.

Dated deliverables against a quote, a work order or a change order.

Each one carries what is being handed over, the day it is due, its value in minor units, and a status that moves planned to in progress to delivered to accepted, every step with the day it actually happened. late_report answers the question anybody actually asks about a schedule: what has slipped, as at a date you name. Lateness is never stored, because a stored late flag is a fact about the afternoon somebody last ran the report; it is derived on the call against the date you pass. Accepted milestones come back as invoice_create-ready items in MAJOR units and quote_create-ready items in MINOR units in one call, with the scale printed against each.

Security and retainer deposits held per client, applied to invoices as a real payment that adds to what was already paid rather than replacing it.

Real Word documents from chat

proposals, contracts, quotes, markdown to .docx, template filling, read existing files.

Chase overdue invoices on an escalation ladder anchored to the due date

reminder 1, reminder 2 and the final notice at configurable gaps, so a letter sent late moves which stage is next and never moves the schedule. Letters go out strictly in order, the late fee is simple interest pro-rata on a 30-day month on what is outstanding the day the letter is written, and part payments lower the ask. letter_render produces Markdown or a self-contained printable HTML page, and nothing is emailed anywhere: the server writes the text and sending it is your act. The overdue list is worst first, the aging buckets the register, and chase_today answers what has to go out today.

Receipts, mileage and expenses ledger that turns billable spend into invoice lines.

The receiving record for purchase orders

what arrived, against which line, in what quantity and condition, with the outstanding balance per line derived on every call.

Image tools without native code

resize, convert, compress, crop, thumbnails, strip metadata, watermark with your business name.

Numbered invoices with tax lines, rendered to a professional PDF, all local.

One card per job, the way the paper one on the dashboard works

client, site, what the job is, currency and scheduled date, then hours per worker at their rate and materials per item, each line rounded half-up to the cent once when it is logged so the running totals are sums of stored line values and can never drift. The status machine moves exactly one step at a time, open to in_progress to done to invoiced to archived, with every step dated in the card's history. Printing renders the card with a signature line for client sign-off, and the daily or weekly summary gives cards touched, hours per worker and value per currency, never mixed across currencies.

A local task board per project

columns, due dates, estimates, overdue view, weekly review, and timers that hand off to the time tracker.

Employee leave and PTO requests

balances, approvals, calendars, and who-is-out summaries.

One register of the equipment you look after and the work done on it

asset_add records a machine with its serial or asset tag, location and currency, and maintenance_log records each service with the day, what was done, the cost in whole cents, the technician, and when the next service falls due as a date or an interval in days. maintenance_due answers what is overdue and by how many days and what falls due within the next N days, computed from the stored dates at the moment you ask, so it can never go stale. asset_history keeps the chronological log with total spend and spend per technician, and maintenance_export hands a date range over as CSV or a Markdown summary per asset.

The mileage log freelancers need at tax time, kept the moment the drive happens

trip_add logs the date, from and to, the distance in miles or km, the purpose and the category, and rate_set records what one mile or km is worth per category and jurisdiction as an effective-dated series, so each trip earns the rate in force on the day it was driven, rounded half-up to the cent. mileage_summary prices a date range per category with totals per currency, trips with no applicable rate listed with the reason and never silently dropped, and mileage_export is the CSV for the accountant, refusing while any non-personal trip is unpriced. Miles and km are never added together, and no rate ships with the server: the figures are yours to verify, and none of it is tax advice.

One install that exposes every tool of all 45 hosted servers, 418 of them.

New-hire onboarding as role-based task templates, with a dated checklist per hire that HR and the manager both read.

Packing slips for a shipment, kept the way a warehouse keeps one

an order reference, a consignee, cartons with a tare weight in whole grams and outside dimensions in whole centimetres, and goods packed into a named carton one line at a time with a per-unit weight. packing_shortfall reports every line as short, complete, over-packed, or packed and not on the order at all, matched on SKU where there is one and on the description where there is not. carton_report gives tare, net, gross, volume, volumetric and chargeable weight per carton and for the shipment at a divisor of 4000, 5000 or 6000 cm3 per kg. Nothing derived is stored, and the slip carries no prices at all: the invoice against the same order is a different document.

PDF tools without native code

merge, split, page ranges, rotate, PAID and DRAFT stamps, best-effort text, business watermark.

Statutory travel allowances on three bundled rate tables

the Polish delegation regulation at home and per country, the HMRC benchmark scale rates inside the UK, and the US GSA CONUS standard. The HMRC overseas per city rates are not bundled and are refused by name rather than guessed.

A petty cash float on the imprest system

a voucher for every receipt out of the tin, a count whenever you like with the difference to the minor unit, and the replenishment that puts the float back to its imprest, with the double entry and an expense_add-ready payload per category. The cheque is imprest minus balance, never the sum of the vouchers, and the difference is its own cash_over_short line. No balance is stored and nothing is posted anywhere.

Check and watch product prices on ordinary shop pages, with history and target alerts.

Purchase requisitions and dated runs of them

a requisition is built once, each run copies its steps, every step is answered pass, fail or not applicable, and a completed run is signed off.

Estimates and quotes on the invoice engine

line items, VAT, validity dates, accept converts to an invoice, PDF, win rate by currency.

Recurring invoices on a schedule

weekly, monthly, quarterly or yearly, generated into the invoice server with PDFs, idempotent per period, with a revenue forecast.

Resumes and cover letters as real Word files from one profile

keyword tailoring, gap analysis, three styles, never invents facts.

Service agreements for freelancers, written before the work starts

the parties, the scope of services, the deliverables, the rate and payment terms, start and end dates, a termination notice period, a liability cap and the governing jurisdiction. agreement_create stores the agreement and returns it rendered as clean Markdown with a signature block, numbered SA-YYYY-NNNN. agreement_checklist lists the missing fields and flags one-sided gaps neutrally before you send it. The status machine moves draft to sent to signed to expired, one dated step at a time, and a built-in clause library covers IP assignment, confidentiality, late payment interest, kill fee and revision rounds. Every render carries the note that it is a template, not legal advice.

Read, query, add columns to and convert xlsx and csv files without corrupting them.

Statements of account and payment chasers built from the invoices, credit notes and deposits you already keep: opening balance, every movement, closing balance, and aging into 0-30, 31-60, 61-90 and over 90 days as at any date you name.

It writes into no book it reports on, and it never invents a late fee.

A supplier directory that does not rot

who you buy from, what they supply, who to contact and how, the payment terms, the lead time in days and notes, with the date each record was last reviewed on it. supplier_list reads the directory A to Z with a category filter and free-text search, supplier_update changes only the fields you pass, and supplier_due_review answers which records have gone stale, most overdue first, with a record never reviewed always due. A second record carrying a name already in the directory is refused, an ambiguous partial name is refused with the candidates, and the SUP number is never reissued. supplier_export hands the directory over as CSV or Markdown.

Track billable time from chat

timers, entries, reports, CSV, invoice-ready totals.

Meeting planner across time zones

convert times, find slots inside everyone's working hours, DST changes, .ics files.

Job orders for trades and field work, kept the way a job card is kept

a client the invoice server already knows, a site address, labour as hours at a rate and parts as a quantity at a unit cost with an optional markup, a status that moves one step at a time with every step dated, a completion report with a sign-off block, and an invoice_create-ready payload. No total is stored: value, hours, materials and VAT are derived from the lines on every call.

Create, inspect and extract zip archives safely from chat

bomb and traversal guards decided from the central directory, CRC checked per entry, bundle a month of invoices and exports.
