ToolForte for AI assistants.
A remote MCP server with 111 tools, free to start. AI models guess; ToolForte calculates. Exact IBAN checksums, VAT amounts, working days, cron schedules, and regex results inside Claude, ChatGPT, Cursor, or any MCP client.
Add it in 30 seconds.
Once connected, the catalog shows every tool with the words to say to your assistant and the call it makes, with example values filled in.
claude mcp add --transport http toolforte https://toolforte.com/api/mcpnpx -y toolforte-mcpCapped 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.
84 of the 111 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.

Server-side rendering with headless Chrome. Each call returns a hosted download link that stays valid for 24 hours, so agents without their own infrastructure can deliver real files. Try 3 renders per day for free. A free API key puts renders on your monthly credit allowance instead. A render costs 25 credits because it boots a headless browser, so Free covers 40 of them a month and ToolForte Pro 300. Run out and you can buy credits in any amount, from 100 for €1.00, on the pricing page. Pass the key as an Authorization: Bearer header on the MCP endpoint; an X-API-Key header works too.

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.

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.
memory_setmemory_getmemory_listmemory_deleteWorkflows: 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_listworkflow_runworkflow_proposeWhat 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.
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.
