Overview

AI-generated overview

Remote MCP server that lets an assistant test regex patterns and validate email addresses, URLs and JSON Schema documents.

What you can do
  • Test a regex pattern against input using Go RE2 syntax and get the full match plus captured groups
  • Check that a string is a single bare RFC 5322 email address (syntax only)
  • Check that a string is a well-formed absolute URL with a scheme and host (syntax only)
  • Validate a JSON document against a draft-07 or 2020-12 JSON Schema, reporting one violation per call
When to use it
Useful when an assistant needs quick, deterministic format checks while writing or reviewing code, data or configuration: confirming an email or URL string is well-formed, trying out a regex, or checking a JSON payload against a schema.
Requirements
A remote streamable HTTP endpoint at apished.com; no package, account, API key or environment variable is declared. Network access to the endpoint is required.
Before you install
Validation is syntax only: email and URL checks do not test deliverability or reachability, and schema validation reports a single violation per call rather than a full list. Regex uses RE2 syntax, so PCRE features such as backreferences and lookaround are unavailable. Inputs are sent to a third-party service.

Installation

In SourceWeft

  1. Open Regex/Email/URL Validator in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.apished%2Fregex-email-url-validator/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

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.

Parametersvaluerequired

jsonschema_validate

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

Parametersschemarequireddocumentrequired

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.

Parametersinputrequiredpatternrequired

url_validate

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

83% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
