# Tools

Free · no signup · nothing to install

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

## llms.txt validator

[The llms.txt validator page](https://serhiichuk.dev/tools/llms-txt/index.md)

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

[The MCP server page](https://serhiichuk.dev/tools/mcp/index.md)

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.
