run_tool
Run any ToolForte tool by name
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.

search_tools
Find a ToolForte tool
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.

validate_iban
IBAN Validator
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.

workflow_list
List saved workflows
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_...

workflow_propose
Propose a workflow for a goal
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_...

workflow_run
Run a saved workflow
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_...
