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 Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability57
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1569 tokens (~313/item across 5 items; 5 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 Management37
- Stability observed for 11 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage92
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 77% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

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 →
audit_ai_readiness Audit AI search readiness ~262
Audit one public web page for what AI answer engines and their crawlers rely on. Reads the page plus its site's robots.txt, llms.txt and sitemap, then reports: for each AI crawler and control token (OAI-SearchBot, ChatGPT-User, GPTBot, Claude-SearchBot, Claude-User, ClaudeBot, PerplexityBot, Perplexity-User, Googlebot, Google-Extended, Applebot, Applebot-Extended) whether robots.txt allows it on this page under RFC 9309 matching; noindex and nosnippet directives; JSON-LD validity against the schema.org vocabulary and Google's LocalBusiness rules; whether the name, phone and address in the markup also appear on the visible page; llms.txt format; canonical tag; and sitemap. Every finding cites the public spec or vendor document behind it, with the date it was read. Results are cached for 10 minutes.
| Name | Type | Req | Description |
|---|---|---|---|
| detail | string | – | "summary" (default) lists only findings that warn, fail or inform; "full" includes passing findings with their sources. |
| url | string | yes | The page to audit, such as example.com or https://example.com/locations/denver. Public http and https only. |
No output schema declared.
No examples provided.
check_entity_consistency Check entity consistency ~191
Compare a business's name, phone, street, city, region and postal code across up to 8 sources, such as its website, Google Business Profile, Facebook page and directory listings. For each source give a url to read (JSON-LD first, then tap-to-call links and page text) and/or the facts shown on it; supplied facts win, and are needed for sites that block automated readers. Formats are normalized ("123 North Main Street, Suite 4" matches "123 N Main St Ste 4", "(406) 555-0100" matches "+1 406-555-0100"), then each field is reported as consistent, variant or mismatch, with the exact fixes. Give business to compare against a canonical record instead of the majority.
| Name | Type | Req | Description |
|---|---|---|---|
| business | object | – | The canonical name, phone and address every source should match. |
| profiles | array | yes | – |
No output schema declared.

Write an llms.txt file in the llmstxt.org format: an H1 with the site name, a blockquote summary, optional details, H2 sections of "- [title](url): note" links, and an Optional section for secondary pages. Give url to build it from the live site (home page, sitemap, and up to 30 pages' own titles and meta descriptions, honoring the site's robots.txt and skipping noindex pages), or give site_name and sections to build it from your own facts; supplied fields override what is read from the site. The result is checked against the format before it is returned. Nothing is published.
| Name | Type | Req | Description |
|---|---|---|---|
| details | string | – | Optional markdown notes between the summary and the link sections. Headings are not allowed there. |
| max_pages | integer | – | How many pages to read from the site, 1 to 30. Default 20. |

How do I install the AI Search Kit MCP server?
AI Search Kit is a hosted endpoint at https://mcp.modernmustardseed.com/ai-search-kit, 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.

What is the AI Search Kit MCP server?
AI Search Kit is an MCP server listed in the public MCP registry as com.modernmustardseed/ai-search-kit. Audits AI-crawler access, structured data and llms.txt on a site, and drafts the fixes. This page covers its hosted endpoint (https://mcp.modernmustardseed.com/ai-search-kit).
Is the AI Search Kit MCP server safe to use?
AI Search Kit scores 75 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 AI Search Kit MCP server expose?
AI Search Kit exposes 5 tools: audit_ai_readiness, generate_local_business_schema, generate_llms_txt, check_entity_consistency, validate_structured_data. Their descriptions and schemas cost roughly 1,470 tokens of context every time the server is loaded.
Does the AI Search Kit MCP server require authentication?
No. We connected to AI Search Kit without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the AI Search Kit MCP server still maintained?
AI Search Kit is still listed as active in the MCP registry. We last reached this channel on 23 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
