Two tools for making a site legible to the agents reading it. Both exist because this site needed them first.

  • llms.txt validator

    Point it at a domain and it checks that site's llms.txt against the llmstxt.org v2 spec: structure, link health, and whether a file at a subpath resolves. Every finding says whether its rule is spec, convention or hygiene, so you can tell a violation from a habit.

    For anyone who publishes an llms.txt and wants to know whether it holds up.

  • MCP server

    A public, read-only MCP endpoint at https://serhiichuk.dev/mcp. Six tools an agent can call directly — search this site, read the CV and the posts, get the services brief, and validate any domain's llms.txt. The page carries copy-pasteable config for five clients.

    For an agent reading this site, and for anyone who would rather have the validator as a tool than as a form.
