Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security81
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token. View diagnostics → Pass
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
- The authorisation server supports Client ID Metadata Documents, the current MCP client-registration mechanism. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability63
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 25123 tokens (~239/item across 105 items; 105 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management16
- Stability check failed: schema churn in the 5 days we've observed: 1 tool removals, 0 breaking changes, 0 auth/transport breaks, 7 additions. See how to fix → Fail
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 99% of tool parameters carry a description.Partial
Tool Safety85
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 2 of 5 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "hometax__tax__payment_due__search_or_pay" implies "pay" and declares readOnlyHint instead, contradicting what its own name says it does. See how to fix → Partial
- An AI judge read all 106 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the XBOSS MCP server?
XBOSS is a hosted endpoint at https://api.xdata.kr/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Composite employment-insurance summary v1: runs COMWEL premium billing notice search then employment detail as internal Jobs, and returns computed employment_insurance_won material. Requires prior comwel session login. No account_link_id is needed here: each step finds its own institution link. If computed is null the result could not be assembled: read computed_error for the reason and do not present the result as complete. Two shapes carry that case: this envelope with partial set to true (we fetched everything - the legs hold it - but could not calculate), or an error whose data carries the same envelope. partial is true whenever the result is incomplete, whether a leg failed or the calculation did.

No account_link_id is needed here: each step finds its own institution link. If computed is null the result could not be assembled: read computed_error for the reason and do not present the result as complete.

What is the XBOSS MCP server?
XBOSS is an MCP server listed in the public MCP registry as kr.xdata/xdata-mcp. Korean national tax and social insurance filings, invoices and payroll data as MCP tools. This page covers its hosted endpoint (https://api.xdata.kr/mcp).
Is the XBOSS MCP server safe to use?
XBOSS scores 73 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 XBOSS MCP server expose?
XBOSS exposes 105 tools: hometax__session__login, hometax__session__user_info, hometax__certificate__list, hometax__certificate__apply__national_tax_payment, hometax__certificate__apply__tax_payment_record, and 100 more. Their descriptions and schemas cost roughly 23,830 tokens of context every time the server is loaded.
Does the XBOSS MCP server require authentication?
Yes. XBOSS asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.
Is the XBOSS MCP server still maintained?
XBOSS is still listed as active in the MCP registry. We last reached this channel on 27 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
