## Trust breakdown
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)
Scored 2026-11-05.
- **Supply Chain Security**: 0/100
- No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.
- Known CVEs could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.
- Install-script risk not yet assessed.
- Dependency health could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.
- **Provenance & Transparency**: 48/100
- Source repository is publicly reachable at the declared URL.
- Provenance check failed: no build-provenance attestation is published.
- Clear OSI-approved license (MIT OR Apache-2.0).
- Actively maintained (last published 3 days ago).
- Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 77/100
- AI-judged instruction clarity (excellent).
- Tool/resource definitions use about 466 tokens (~93/item across 5 items; 5 tools + 0 resources), lean.
- Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
- No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 100/100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).
- 100% of tool parameters carry a description.
- Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
- Implements a current MCP spec version (2026-07-28).
**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## MCP tools (5)
### `xml_check` (~38 tokens)
Check whether a document is well-formed, and report the line and column if it is not.
Input parameters:
- `xml` (string, required): The XML document
Output parameters:
- `nodes` (integer): How many nodes the document has.
- `well_formed` (boolean): Always true: a document that is not well-formed is an error, not a result.
### `xml_format` (~134 tokens)
Format an XML document with configurable indentation (spaces) and empty element style, or minify it. Use this to pretty-print or compact XML.
Input parameters:
- `empty_elements` (string|null): Empty element style: 'self-closing' (``), 'spaced' (``), or 'expanded' (``). Default is 'self-closing'.
- `indent` (integer|null): Spaces per indentation level (e.g. 2 or 4). Set to 0 or omit to minify without extra whitespace.
- `xml` (string, required): The XML document
Output parameters:
- `formatted_size` (integer): Formatted size of the XML in bytes.
- `original_size` (integer): Original size of the XML in bytes.
- `xml` (string): The formatted XML.
### `xml_inspect` (~55 tokens)
Summarise a document's structure: element counts, depth, the element names present, and the namespaces it uses. Use this to understand a document's shape before querying it.
Input parameters:
- `xml` (string, required): The XML document
Output parameters:
- `elements` (object): Every element name present, with how many times it occurs.
- `max_depth` (integer): The deepest element, counting the root as 1.
- `namespaces` (object): Every namespace URI in use, with how many elements are in it.
- `root` (string): The local name of the root element, or `none`.
### `xml_query` (~122 tokens)
Evaluate an XPath 1.0 expression against an XML document and return the matching values. Use this instead of reading a large document into context.
Input parameters:
- `namespaces` (object): Namespace prefixes used in the expression, mapping prefix to URI, e.g. {"m": "urn:example"}. A prefix must be bound here; it is not read from the document. Call xml_inspect to see which namespaces a…
- `xml` (string, required): The XML document
- `xpath` (string, required): An XPath 1.0 expression
Output parameters:
- `count` (integer): How many nodes matched. A scalar expression counts as one.
- `values` (array): The matched values in document order, empty text omitted. A scalar expression -- a number, string or boolean -- is one value.
### `xml_validate` (~53 tokens)
Validate an XML document against an XML Schema (XSD). Returns every violation with the path to the element it concerns.
Input parameters:
- `xml` (string, required): The XML document
- `xsd` (string, required): The XML Schema
Output parameters:
- `valid` (boolean): Whether the document conforms to the schema.
- `violations` (array): Every violation found; empty when the document is valid.

## Common questions
### What is the oxml-mcp server?
oxml-mcp is listed in the public MCP registry as io.github.sebastienrousseau/oxml-mcp. XML tools for agents: XPath queries, inspection, and schema validation in Rust. This page covers its container image (ghcr.io/sebastienrousseau/oxml-mcp).
### Is the oxml-mcp server safe to use?
oxml-mcp scores 55 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
### What tools does the oxml-mcp server expose?
oxml-mcp exposes 5 tools: xml_check, xml_format, xml_inspect, xml_query, xml_validate. Their descriptions and schemas cost roughly 402 tokens of context every time the server is loaded.
### Is the oxml-mcp server still maintained?
oxml-mcp is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
### What licence is the oxml-mcp server under?
oxml-mcp declares the MIT OR Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
