Your tools, settings and files live in ToolDurus, not in the model. Use them in our built-in chat, or connect the AI app you already pay for. Every client sees the same storage, so a file you upload in the web file manager is instantly available to the model, and whatever the model creates lands back in your folders.
Want sensitive documents to stay at home? Pair your own local model through Ollama and the conversation runs on your machine.
Browse the store.
These are the real tool names your model sees. Switch on only what you need; dependencies such as storage browsing are added for you. Every tool works on files in your ToolDurus storage, and new ones land in the store all the time.
From sign-up to first tool call in a few minutes.
Sign up with just an email
No password at the start. Verify your email and set a password whenever you like. Storage tools are switched on for you.
Switch on the tools you need
Pick from the catalog. Tools that need credentials, like your Seznam.cz mailbox or a ČÚZK API key, store them encrypted.
Get your personal MCP URL
It looks like tools.tooldurus.com/mcp/<token>. Treat it like a password; you can regenerate it any time.
Ask in plain language
“Fill this contract template”, “convert the DGN to DWG”, “email the invoice to Jana”. The model picks the right tools and runs them.
Use ToolDurus Chat
One click from your console, no setup. Switch between Gemini 2.5 Flash, Gemini 2.5 Pro and your paired local model, attach files up to 50 MB, search old conversations and stop a run mid-way.
One storage, shared by you and your models.
Upload in the web file manager, the chat or a link you send to someone. The model reads by file token, writes into sensible output folders, and you can always roll back what it changed.
A standard MCP server. Give your agents hands and feet.
Streamable HTTP, stateless JSON-RPC, nothing proprietary. Point any MCP-capable framework at it, or call it with plain HTTP from your own code.
# list the tools you have switched on curl https://tools.tooldurus.com/mcp \ -H "Authorization: Bearer $TOOLDURUS_TOKEN" \ -H "Content-Type: application/json" \ -H "Accept: application/json, text/event-stream" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Compact mode: your context window stays free.
Every tool schema eats tokens before the model has read a word. Turn on compact mode and your client sees two meta tools, tooldurus_tools to look up a schema on demand and tooldurus_call to run it. Large tool families keep short schemas and explain the details through action="help" only when asked.
One place to decide what your team's AI may do.
For companies, schools, nonprofits and public bodies. Admins set policy once; it applies to every member in the chat and in external AI apps alike.
Policies you can lock
Enforce sign-in codes by email, per-chat storage isolation, whether models may read attachment content directly, and compact tool mode. Locked settings can't be changed by members.
Approved tools and models
Allowlist which tools and which chat models members may use, activate them for everyone in one click, and share tool settings such as a team mailbox centrally.
Shared organization drive
A team drive next to everyone's personal one, plus a read-only folder for reference documents the AI can consult but never change. Make the whole drive admin-write-only if you need to.
One local model for the team
Run a model on your own hardware through Ollama and offer it to all members at once, so sensitive work never leaves the building.
External access on or off
Decide whether members may connect ToolDurus to outside AI apps. Switch it off and tokens are hidden and refused, while ToolDurus Chat keeps working.
Members and devices
Invite by email (links valid 7 days), promote more admins, see each member's signed-in devices and sign them out remotely.

Built for three kinds of users.
Everyday users
Let the AI you already use handle your Seznam.cz email, fill in forms, convert photos from your phone, make a QR payment code or clean up a podcast recording.
Professionals and organizations
Architects and engineers with DWG, DGN and PDF/A for permit portals; surveyors with GIS and the cadastre; lawyers reviewing contracts with tracked changes; offices with Excel and mail merge.
Developers
Production-grade tools behind one MCP endpoint, instead of wiring up LibreOffice, GDAL, FFmpeg and veraPDF yourself.
