Anlyon alternative
Run the operations that matter as governed actions.
Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.
Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

explain_errorExplain an XML parsing or schema validation error message: what it means, why it happens and how to fix it, with an example.No findings
Why it is in this group
- The name "explain_error" says "explain": a word for reading.
Description, as the server wrote it Explain an XML parsing or schema validation error message: what it means, why it happens and how to fix it, with an example. Understands libxml2 (xmllint, PHP, Python lxml, xmlvalid), Java (Xerces cvc-* codes, SAXParseException) and .NET (System.Xml) wording; paste the message as reported, stack trace prefix included. No API key needed.

explain_ruleExplain an e-invoicing business rule by its id, such as BR-CO-15, BR-DE-1, PEPPOL-EN16931-R001 or a national CIUS rule: its message, level, the rule sets it belongs to, why invoice…No findings
Why it is in this group
- The name "explain_rule" says "explain": a word for reading.
Description, as the server wrote it Explain an e-invoicing business rule by its id, such as BR-CO-15, BR-DE-1, PEPPOL-EN16931-R001 or a national CIUS rule: its message, level, the rule sets it belongs to, why invoices fail it and how to fix them. No API key needed.

- readOnlyHint: true
get_validationThe status and result of a validation started with validate_xml that was still running when it returned (status "queued" or "running").No findings
Why it is in this group
- The name "get_validation" says "get": a word for reading.
Description, as the server wrote it The status and result of a validation started with validate_xml that was still running when it returned (status "queued" or "running"). Results are kept for 24 hours.

- title: Get Validation
- readOnlyHint: true
search_schemasSearch xmlvalid's catalog of official XML schemas (UBL, CII, Peppol, XRechnung, Factur-X, ISO 20022, HL7, sitemaps…) by name, namespace, root element or area.No findings
Why it is in this group
- The name "search_schemas" says "search": a word for reading.
Description, as the server wrote it Search xmlvalid's catalog of official XML schemas (UBL, CII, Peppol, XRechnung, Factur-X, ISO 20022, HL7, sitemaps…) by name, namespace, root element or area. Returns each schema's slug to pass to validate_xml, its version and the business rules it checks. No API key needed.
Annotations the server declares
- title: Search Schemas
- readOnlyHint: true
validate_xmlValidate an XML document with xmlvalid: well-formedness, an XSD, DTD or RelaxNG schema, and for e-invoices the Schematron business rules of EN 16931, Peppol BIS, XRechnung, Factur-…Reads text others writeCan send data outNo findings
Why it is in this group
- The name "validate_xml" says "validate": a word for reading.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
- outboundThe input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
Claude Code: ask, because it is tagged outbound.
Description, as the server wrote it Validate an XML document with xmlvalid: well-formedness, an XSD, DTD or RelaxNG schema, and for e-invoices the Schematron business rules of EN 16931, Peppol BIS, XRechnung, Factur-X and national formats. Pass the document as `xml` (its text) or `url` (a public http(s) address), and a `schema`: a catalog slug from search_schemas, a saved schema ("@orders-v3"), or "auto" to use the e-invoice profile the document names. Without a schema only well-formedness is checked. Returns valid, errors and warnings with line, column, message, rule and a help_url explaining each. Counts as one API validation of the key's monthly quota.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
Exfil surface
Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.
No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data.
- Reads private data0
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write1
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out1
- Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.
Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.
Findings
Matches of fixed checks, with the text they matched.
No check matched anything in these tool definitions. That is not a safety guarantee.
History
Changes to its tool definitions and to its remote endpoint, newest first.
No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.
Install
Pinned to version 1.0.0. Values in angle brackets are yours to fill in.
claude mcp add --transport http xmlvalid https://xmlvalid.com/mcpclaude mcp add --transport http xmlvalid https://xmlvalid.com/mcpRun in a terminal.
Claude Code permissions
Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.
{
"permissions": {
"allow": [
"mcp__xmlvalid__get_validation",
"mcp__xmlvalid__search_schemas",
"mcp__xmlvalid__explain_error",
"mcp__xmlvalid__explain_rule"
],
"ask": [
"mcp__xmlvalid__validate_xml"
],
"deny": []
}
}Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as xmlvalid. Review it before you use it.

Pin
Keep the decision: fail CI when the tools change, follow every change, or show a badge.
Pin in CI
