Changes things 1Claude Code: ask
check_if_listedCheck whether a company is listed in the ISMS Directory.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it Check whether a company is listed in the ISMS Directory. Returns the listing when found, close matches otherwise, and the free submission URL when it is not listed.
Annotations the server declares
- title: Check if a company is listed
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
Only reads 3Claude Code: allow
get_service_detailsFull public profile of one listed service (description, frameworks, regions, industries, client sizes, languages, website, directory page).Reads private dataReads text others writeNo findings
Why it is in this group
- The name "get_service_details" says "get": a word for reading.
What it can reach
- private-dataThe description's first sentence says "directory": it reads files.
- untrusted-inputThe description's first sentence says "website": it reads web pages, which anyone can write.
Description, as the server wrote it Full public profile of one listed service (description, frameworks, regions, industries, client sizes, languages, website, directory page). Matches the name case-insensitively, then by partial name.
Annotations the server declares
- title: Get service details
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
list_categoriesList every tag used in one catalog dimension with the number of listed services carrying it.No findings
Why it is in this group
- The name "list_categories" says "list": a word for reading.
Description, as the server wrote it List every tag used in one catalog dimension with the number of listed services carrying it. Use the returned tags as exact filter values for search_services.
Annotations the server declares
- title: List catalog tags
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
search_servicesSearch the ISMS Directory catalog of ISO 27001, SOC 2, GDPR, DORA, NIS 2 and other compliance service providers (consultants, auditors, platforms, training).Reads private dataNo findings
Why it is in this group
- The name "search_services" says "search": a word for reading.
What it can reach
- private-dataThe description's first sentence says "search" and "directory": it reads files.
Description, as the server wrote it Search the ISMS Directory catalog of ISO 27001, SOC 2, GDPR, DORA, NIS 2 and other compliance service providers (consultants, auditors, platforms, training). Filters are exact tags; several frameworks are combined with AND. Use list_categories first if you are unsure of a tag. Results are sorted by name, not ranked. Same data as GET https://ismsdirectory.com/api/search.
Annotations the server declares
- title: Search compliance services
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
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 outbound.
- Reads private data2
- 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 out0
- 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.
Remote posture
What anyone on the internet sees at the remote endpoint: an anonymous initialize and tools/list, and the public OAuth metadata.

The endpoint served tools/list without credentials, and the list has 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

Install
Pinned to version 1.4.0. Values in angle brackets are yours to fill in.
claude mcp add --transport http isms-directory https://ismsdirectory.com/api/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__isms-directory__search_services",
"mcp__isms-directory__get_service_details",
"mcp__isms-directory__list_categories"
],
"ask": [
"mcp__isms-directory__check_if_listed"
],
"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 isms-directory. Review it before you use it.
