Capped at 200 requests a day per client session. Need more volume or REST access? An account gives you 1,000 credits a month, and ToolForte Pro 7,500: 7,500 API or MCP tool calls, or 750 AI generations, or 300 renders, or any mix.
Small by default. Everything within reach.
A session that loads all 177 tools spends tens of thousands of tokens before the first message, and models pick worse from a long list. So the plain URL lists 14 tools: a core of the exact answers people ask for most, the workflow tools, and three meta tools. Every other tool stays callable by name, and search_tools, describe_tool and run_tool find, explain and run any of them. Want a different list? Say so in the URL.
https://toolforte.com/api/mcp
The core: 14 tools listed, all 177 reachable.
https://toolforte.com/api/mcp?tools=all
Every tool listed up front, the way a registry scans it.
https://toolforte.com/api/mcp?tools=pdf,dutch,validate_iban
Jobs from /everything and tool names, comma separated.
Job names are the sections of /everything: smaller-or-different-file, pdf, text, data-formats, check-a-list, money, dutch, dates, test-data, encode-decode, web-pages, design, ai, documents, units-health-school, for-an-assistant. With the npm bridge, set TOOLFORTE_TOOLS=all or a list.
150 of the 177 tools are deterministic: zero guessing.
Every tool returns exact, deterministic output computed by real code, so the AI answer you get is correct instead of plausible.

profit_margin
Gross margin, markup and profit on one sale. In margin mode give the cost and the selling price; in price mode give the cost and the margin you want and it returns the price to charge. Margin is profit over the price, markup is profit over the cost, and both come back either way.

Margin Markup
margin_markup
Give any two of cost, revenue and gross margin and this solves for the rest, including the markup. Use costRevenue when you know both amounts, costMargin to price up from a cost, and revenueMargin to work out what a product may cost to hit a margin at a fixed price.

Commission
commission
Commission on a sale and what is left after it. Flat mode pays one rate on the whole amount; tiered mode works like tax brackets, each rate paid only on the slice of the sale inside its band, which is why the effective rate lands between the lowest and highest tier.

Inflation Adjust
inflation_adjust
What an amount is worth after inflation, or what it was worth before. Fixed mode applies a rate you choose over a number of years. CPI mode uses the published US CPI-U annual averages from 1913 to 2025, so two years can be compared with the figures the BLS actually reported.

Retirement Savings
retirement_savings
Project a pension pot from what is saved now, what goes in every month, the return and the years left until retirement. Returns the pot at the retirement age, the same pot restated in today's money at an inflation rate, what the 4% rule would pay per month, and a year-by-year table.

Debt Payoff
debt_payoff
Take a list of debts with balance, APR and minimum payment, add whatever extra you can pay each month, and simulate both payoff strategies: snowball, which clears the smallest balance first, and avalanche, which clears the dearest first.

Macros
macros
Daily protein, carbohydrate and fat grams for a calorie target and a goal. Calories come from the Mifflin-St Jeor basal rate times an activity factor, shifted by 500 kcal down to lose or 300 kcal up to gain and never below 1200, and are then split three ways: balanced 30/40/30, low carb 40/20/40 and high protein 40/30/30.

Sleep Times
sleep_times
Bedtimes or wake-up times that complete whole sleep cycles. From one clock time it counts six, five, four and three blocks of 90 minutes, plus the 15 minutes an average adult needs to fall asleep, so the alarm lands between cycles instead of in deep sleep. This is an indication, not medical advice.

Water Intake
water_intake
Daily water intake from weight, activity and climate.

Body Fat
body_fat
Body fat percentage from tape measurements using the US Navy method.

Bmr
bmr
Basal metabolic rate from sex, age, height and weight, by both Mifflin-St Jeor (1990) and the revised Harris-Benedict (Roza and Shizgal, 1984), so the spread between them shows the uncertainty.

Pregnancy Due Date
pregnancy_due_date
Estimated due date and current week from the last period or conception date.

Ovulation Window
ovulation_window
Fertile window and ovulation day from the last period and cycle length.

Date Add Subtract
date_add_subtract
Add or subtract days, weeks, months or years from a date and get the date you land on, written out with its weekday. The arithmetic is calendar aware and runs in UTC, so leap years and month lengths are handled and the answer never shifts with a time zone.

Fractions
fractions
Add, subtract, multiply or divide two fractions, mixed numbers included, and get the answer reduced to lowest terms. The arithmetic is exact whole-number arithmetic, so nothing is rounded through a decimal on the way, and the result comes back as a fraction, a mixed number and a decimal.

Ratio
ratio
Reduce a ratio to lowest whole-number terms, solve a proportion A:B = C:D for the one value left out, or scale a ratio by a factor for a recipe or a mix. Reducing is exact whole-number arithmetic, so a ratio written with decimals is scaled to integers first rather than rounded.

validate_card_number
Check a payment card number the way a checkout form does: the Luhn checksum that every major network uses to catch a mistyped digit, and the scheme behind the prefix (Visa, Mastercard, Amex, Discover, JCB, Diners).

remove_line_breaks
Join lines that were broken in the wrong places back into flowing text.

tsv_to_csv
Convert tab separated text to CSV, or CSV back to TSV, quoting every field that needs it.

csv_extract_columns
Keep, drop or reorder the columns of a CSV. Columns are named by header text or by 1-based position, and the order they are asked for is the order they come back in, so the same call also reorders.

AI tools: judgement your agent can call.
These 6 tools are a model call each, wrapped in a prompt ToolForte maintains and a typed answer your agent can rely on: a scam verdict with the evidence quoted, a spreadsheet formula with its pitfalls, a SQL query with its assumptions. The same tools answer at POST /api/v1/ai/<tool>. Try 5 calls a day for free; with an API key a call costs 10 credits from the same balance as everything else, so Free covers 100 of them a month. The answer is an assessment, not a fact: the scam checker says so in every reply.

Memory: what your agent knows tomorrow.
Agents forget. Every new conversation starts empty, so work that spans days gets repeated instead of continued. These 4 tools give your agent a private store it can write to now and read back in a week: what it already processed, a running list, a decision and why. Being able to read it back next week is the same thing as it being kept, so be clear about what that means: these entries are stored on ToolForte servers. They are scoped to your API key, so nobody else can read them, and at 0 credits they never touch your monthly balance. They are kept for 30 days on Free and 365 days on ToolForte Pro. Get a free API key and pass it as an Authorization: Bearer header, or as X-API-Key.

Workflows: many tools, one call.
Your agent can run a saved workflow over MCP, by id, in one call. A workflow is a sequence of these tools where each step reads what an earlier step returned, so a job that would take five coordinated calls takes one. Build them in the builder. A workflow belongs to an account rather than to a key, so these 3 tools need an API key and refuse without one: an anonymous caller has no account and therefore nothing to run. Each step costs what its own tool costs, normally 1 credit, and the credit for the workflow_run call itself pays for the first step instead of being charged on top. The result names every step that ran, what it cost, and any value a tool replaced with its own, so an agent is never acting on a substitution it was not told about.
Workflow List
workflow_list
See the workflows on your account: their ids, the inputs each one wants, and what a run costs
Workflow Run
workflow_run
Run one by id and get back every step, what it produced, and what it cost
Workflow Propose
workflow_propose
Describe a job in a sentence and get a workflow built from real ToolForte tools, saved to your account if you ask
What this lets your agent do.
A language model can write an invoice but not hand you the PDF, and it cannot see a page that renders client-side. These are the jobs that stop being impossible once the server does the work.
Reports people can open
Your agent drafts the summary, html_to_pdf turns it into a PDF, and the reply contains a real download link instead of a wall of Markdown.
Reading the modern web
Most sites render in the browser, so a plain fetch returns an empty shell. read_page runs the page and gives back what a visitor would actually see.
Work that spans days
Store progress with memory_set and pick it up in tomorrow's session, instead of starting the same research over because the chat ended.
Checks that must be exact
IBAN, VAT and BSN validation are arithmetic, not judgement. Let the server compute them so the model cannot round the truth.
Jobs with more than one step
Save the sequence once as a workflow, then call workflow_run with an id instead of orchestrating five tool calls and hoping the shapes line up.
What it costs.
There is no separate MCP subscription. MCP is included on both plans, and it spends the same monthly balance as the REST API and the AI tools, so you never have to guess in advance how much of each you will need. Heavy work costs more than light work, because that is what it costs us.
Without an API key
Free. All 150 deterministic tools, plus 3 renders a day, so an agent can prove it works before anyone signs up.
Agent memory
Free on both plans, always. At 0 credits it costs us a database row, and we would rather you keep the server connected.
Workflows
1 credit per step, charged step by step as the run goes, and the credit for the workflow_run call itself pays for the first step rather than being added to it. A three step workflow costs three credits, the same as calling the three tools yourself. Needs an API key, because a workflow belongs to an account.
With an account
MCP draws on the same monthly credit balance as the REST API and the AI tools. One MCP call costs 1 credit, a render 25. Free gives 1,000 credits a month, ToolForte Pro 7,500 for €19 a month or €190 a year.
Running out
Buy credits in whatever amount you need, from 100 for €1.00. A free account is enough, no subscription required. Bought credits never expire, are spent only after the monthly allowance, and each tool result tells you what is left.
