Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

email_validate

Checks value is a single, bare RFC 5322 email address — syntax only, not a deliverability check. user@localhost is valid (no TLD required). "Name <email>" display syntax is rejected.

jsonschema

jsonschema_validate

Validates document against schema (JSON Schema draft-07 or 2020-12). Reports one specific violation per call, not an aggregated list.

regex

regex_match

Tests input against pattern (Go's regexp package: RE2 syntax, not PCRE — no backreferences or lookaround; use inline flags like (?i) for case-insensitive matching). Returns the full match and captured groups.

url

url_validate

Checks value is a well-formed absolute URL (has both a scheme and a host) — syntax only, not a reachability check.

It exposes 4 tools, read directly from the server on our last check. Among them: email_validate, jsonschema_validate, regex_match, url_validate. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 193 ms. The bar chart above shows every period we have measured.

How do I connect Regex/Email/URL Validator?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Regex/Email/URL Validator need an API key?

No. Regex/Email/URL Validator completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
