Tools now carry an agent-readiness grade
The directory could only ever tell you whether a tool was reachable by a machine at all: it published an llms.txt or an MCP server, or it did not. That is a useful answer, but it treats every tool on the list as the same. Tools now carry a letter grade instead, so you can see at a glance how far a product has actually gone.
What's new?
- Tool pages show an agent-readiness grade beside the repository, docs, and MCP links.
- The full scoring is published on the agent-ready page: every signal, what it is worth, and where each band starts.
- Grades are worked out from checks we already run against each product, and recalculated every time a page loads, so a grade can never describe a product as it used to be.
- Nothing is self-reported. The only way to change a grade is to change the product.
- Tools that publish an MCP server you run locally now get credit for it, rather than being ranked below tools that happen to host theirs.
We only publish a grade of C and above. Not publishing an llms.txt or an MCP server is a perfectly ordinary thing for a good tool to be, and this directory is not here to put a failing mark on someone else's work.
