Detects the direction from the input unless a mode is given. Arguments: value, mode?. Same result as POST /api/v1/tools/roman-numeral-converter.

  shallow
• rot13

  Apply ROT13, or any Caesar shift from 1 to 25, to a text. Letters rotate and keep their case; digits and punctuation stay as they are. Decoding with shift 13 gives the original back. Arguments: text, shift?, decode?. Same result as POST /api/v1/tools/rot13.

  shallow
• run_tool

  Run any ToolForte tool by name with its arguments, whether or not it is listed in this session. The result, the cost and the metering are exactly what the tool gives when called directly; run_tool itself is free. Find names with search_tools and schemas with describe_tool.

  shallow
• search_tools

  Find ToolForte tools by what you want done, for example "iban", "vat", "pdf merge", "working days", "csv to json", "screenshot". ToolForte has over a hundred exact tools (validation, conversion, Dutch tax and dates, test data, files, AI); a session lists a small core of them and this is how you reach the rest. Returns the best matches with their arguments and cost. Then call the tool by name, or through run_tool. Free.

  shallow
• sort_lines

  Sort the lines of a text A to Z, Z to A, by length, in natural numeric order, or shuffle them with a seed. Can drop duplicates and ignore case. Returns the sorted text and line count. Arguments: text, mode?, caseInsensitive?, removeDuplicates?, reverse?, seed?. Same result as POST /api/v1/tools/sort-lines.

  shallow
• split_csv

  Split one CSV into parts, either every N rows or one part per distinct value of a column. Every part keeps the header. Returns the parts as CSV text with a name each. Arguments: text, by, size?, column?, name?. Same result as POST /api/v1/tools/csv-split.

  shallow
• split_tip

  Tip on a restaurant bill at a percentage, the total, and the even split per person. Can round the total up to the next whole unit, in which case the tip absorbs the difference. Arguments: bill, tipPercent?, people?, roundUp?. Same result as POST /api/v1/tools/tip-calculator.

  shallow
• strip_metadata

  Remove hidden metadata from a file behind a public URL (max 50MB) and return a cleaned copy: EXIF, XMP, IPTC and comments from JPEG, PNG and WebP; the Info dictionary and XMP stream from PDF; author, company, editing time and other document properties from DOCX, XLSX and PPTX. Picture data and document content are untouched. The result lists exactly what was removed. Returns a hosted download URL valid for 24 hours. Free demo: 3 renders/day. With a free ToolForte API key (Authorization: Bearer tf_..., get one at https://toolforte.com/developers), which spends your monthly unit balance: 25 units per render.

  shallow
• test_regex

  Run a JavaScript regular expression against a test string using a real regex engine. Returns all matches with capture groups and indices.

  shallow
• text_diff

  Compute an exact line-based diff between two texts with add/remove/unchanged stats.

  shallow
• translate_code

  Translate a piece of code from one programming language to another (for example Python to TypeScript, JavaScript to Go, VBA to Python, jQuery to plain JavaScript, SQL between dialects). Keeps the behaviour, uses the idioms of the target language, and lists what could not be translated one to one: libraries without an equivalent, integer sizes, error handling, concurrency. Meant for snippets and single files up to about 10,000 characters, not whole projects. Costs one AI generation (10 credits) with an API key; a few free demo calls per day without one. Same result as POST /api/v1/ai/code-translate.

  shallow
• url_encode

  URL-encode or decode a string with exact percent-encoding.

  shallow
• url_screenshot

  Take a PNG screenshot of a public web page with headless Chrome. Returns a hosted download URL valid for 24 hours. Free demo: 3 renders/day.

  shallow
• validate_email

  Validate email address syntax and detect common domain typos (e.g. gmial.com).

  shallow
• validate_iban

  Check whether an IBAN is well formed: the mod-97 checksum, the country code, the length that country's IBAN must have, and whether every position holds the kind of character that country allows there (mod-97 turns letters into numbers, so on its own it cannot see a capital O typed in place of a zero). Returns validity, country, and where known the bank identifier printed inside the IBAN. This is a format check, not a bank check: a passing IBAN can still name a bank code that never existed or has since merged away, and says nothing about whether the account exists or can receive a payment. For twelve countries it also verifies the national check digit that the bank computes over the bank code and account number (BE, FR, MC, ES, IT, SM, PT, SI, PL, TN, EE, HU); nationalCheck 'failed' there means the number is very probably invented, since that digit cannot be back-computed the way the mod-97 pair can. Absent nationalCheck means not checked, never approved. For Dutch IBANs it also names the institution behind the four-letter bank code, including codes that no longer issue accounts; an unrecognised code does not make the IBAN invalid. A territory that borrows another country's IBAN (Reunion, Guernsey, Aland and the like) is reported with the prefix it actually uses, since no IBAN starts with RE or GG. Never guess whether an IBAN is well formed: use this tool. Do not present a pass as confirmation that money can be sent.

  shallow
• week_number

  The ISO 8601 week number and ISO year for a date, with the Monday and Sunday of that week, plus the US (Sunday-based) and UK/EU week numbers. Defaults to today when no date is given. Arguments: date?. Same result as POST /api/v1/tools/week-number.

  shallow
• word_frequency

  Count how often each word occurs in a text and return a ranked table, most frequent first, with counts and percentages. Can ignore case, skip short words and drop common stop words. Arguments: text, ignoreCase?, minLength?, excludeStopWords?, limit?. Same result as POST /api/v1/tools/word-frequency-counter.

  shallow
• workflow_list

  List the workflows saved to the ToolForte account this API key belongs to. A workflow runs several ToolForte tools in order, passing each one the output of an earlier step, so it does a whole job in one call instead of you orchestrating the steps yourself. Returns each workflow's id, the inputs it expects, the steps it runs and what a run costs. Call this first: workflow_run needs an id from here. Requires an API key, because a workflow belongs to an account. Get a free key at https://toolforte.com/developers and send it on the MCP connection as the header Authorization: Bearer tf_...

  shallow
• workflow_propose

  Describe a job in plain words and get back a workflow built only from tools this server really has: a name, the inputs it needs, and the steps in order, each with one sentence on why it is there. The proposal is honest about gaps: partial is true and missing names what could not be done, and when nothing here fits the answer says so instead of inventing a step. Send save: true to keep it on the account, after which workflow_run can run it by the returned id. Costs 10 credits, the price of one AI generation, charged once per proposal. Requires an API key linked to a ToolForte account. Get a free key at https://toolforte.com/developers and send it on the MCP connection as the header Authorization: Bearer tf_...

  shallow
• workflow_run

  Run one saved workflow by id and return what every step produced. Get the id and the input keys from workflow_list. Each step costs the credits its own tool costs, normally 1 per step, and the credit for this call counts as the first step's rather than being charged on top. Steps run in order and stop at the first failure; the result says which step stopped it and what was spent up to that point. Check the "substitutions" field when it is present: it lists values a step supplied that the tool replaced with its own, which means the run succeeded on a value you did not send. Requires an API key, because a workflow belongs to an account. Get a free key at https://toolforte.com/developers and send it on the MCP connection as the header Authorization: Bearer tf_...

  shallow
• working_days_between

  Count working days (Mon-Fri) between two dates inclusive, optionally excluding Dutch public holidays. Exact date math for SLA, payroll, and planning questions.

  shallow
• write_email

  Write an email from a purpose, a recipient and the key points, in a chosen tone (formal, friendly, persuasive, urgent, apologetic or neutral) and length. Returns a subject line and the body, ready to paste, in the requested language or the language of the key points. Good for follow-ups, requests, complaints, cold outreach, thank-you notes and apologies. Costs one AI generation (10 credits) with an API key; a few free demo calls per day without one. Same result as POST /api/v1/ai/email-write.

  shallow
• xml_to_json

  Parse XML into a JSON object keyed by the root element. Attributes become keys with a prefix ("@id"), text beside attributes or children lands under "#text", repeated elements become arrays, and namespace prefixes can be dropped. Malformed XML is reported with the line number; DTD-declared entities are not expanded. Arguments: xml, attributePrefix?, dropNamespaces?, indent?. Same result as POST /api/v1/tools/xml-to-json.

  shallow
• yaml_to_json

  Parse YAML text and return both the value and its JSON text. Reads maps, lists, inline [lists] and {maps}, quoted and block scalars and comments. Anchors, aliases, merge keys, tags and multi-document files are not supported and are reported with the line number. Arguments: yaml, indent?. Same result as POST /api/v1/tools/yaml-to-json.
