Free tools for building with AI agents
Five tools for the jobs that come up when you build with models and agents: counting tokens, wiring an MCP server into your editor, telling AI crawlers what they may read, and checking whether your organisation is ready. Each one runs in your browser with no sign-up, and nothing you type is sent to Olano.
The tools
Free to use, no account, and each with a guide underneath that explains the rules it applies.
Token counter
Count tokens exactly for OpenAI's tokenizers, estimate Claude and Gemini, and see what a prompt costs.
MCP config generator
Build mcp.json, .mcp.json or config.toml for nine MCP clients from one form, and check existing configs for errors and plaintext secrets.
llms.txt generator
Build an llms.txt from a form, URL list or sitemap, and validate any file against the v2 spec.
Robots.txt checker
Test a robots.txt against 22 search and AI crawlers, see the deciding rule, and generate a new file.
AI readiness assessment
Score your organisation across six dimensions and get next steps and a first agent to try, with no sign-up.
How we build them
We use these tools ourselves while building and running Olano, the platform for persistent AI agents. Every fact a tool relies on, from a tokenizer's encoding to an MCP client's config format to a crawler's user-agent token, is checked against the publisher's own documentation, linked from the tool's page and dated, so you can see how current it is. The logic behind each tool has its own unit tests, and the counts, checks and generated files are worked out in your browser rather than on a server.
None of them collects what you type. The site counts that a tool was used, never the text you put into it, and nothing is stored after you close the page. When a vendor changes a format or a price, we update the tool and the date on its page.
Building for a Singapore business?
Olano Studio's site has free tools for Singapore businesses: a UEN and company search over ACRA's open data, a GST calculator, a GST tax invoice generator, a WhatsApp link and QR code generator, and a working days calculator with the 2026 and 2027 public holidays.
To go further than a tool, see how the Olano platform works, the plans, or the resources library for the guides behind the topics these tools touch.
