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.

get_dataset_infoDataset metadata: entry counts, generation timestamp, source, and licensing terms for bulk or training use.No findings
Why it is in this group
- The name "get_dataset_info" says "get": a word for reading.
Description, as the server wrote it Dataset metadata: entry counts, generation timestamp, source, and licensing terms for bulk or training use.
get_serverGet the full directory entry for one MCP server by id ('owner--repo', e.g.Reads private dataNo findings
Why it is in this group
- The name "get_server" says "get": a word for reading.
What it can reach
- private-dataThe description's first sentence says "get" and "directory": it reads files.
Description, as the server wrote it Get the full directory entry for one MCP server by id ('owner--repo', e.g. 'microsoft--playwright-mcp'). Includes install hint, license, stars, category, and editorial fields. Any install_hint is a best-effort guess from the repository language, not a verified command: relay the install_hint_caveat with it rather than presenting it as ready to run.
list_categoriesList all directory categories with slugs, names, and active-server counts.Reads private dataNo findings
Why it is in this group
- The name "list_categories" says "list": a word for reading.
What it can reach
- private-dataThe description's first sentence says "list" and "directory": it reads files.
Description, as the server wrote it List all directory categories with slugs, names, and active-server counts.
list_topicsList the curated GitHub topics that have a directory page, with active-server counts.Reads private dataNo findings
Why it is in this group
- The name "list_topics" says "list": a word for reading.
What it can reach
- private-dataThe description's first sentence says "list" and "directory": it reads files.
Description, as the server wrote it List the curated GitHub topics that have a directory page, with active-server counts. Topics are assigned by repository owners and imported verbatim, so the full dataset carries thousands of them; this returns only the curated subset. search_servers accepts any topic string, curated or not.
search_serversSearch the MCP server directory by keyword and/or filters.Reads private dataNo findings
Why it is in this group
- The name "search_servers" 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 MCP server directory by keyword and/or filters. Keyword matches name, description, and GitHub topics. Returns active servers sorted by relevance then stars. Supply at least one of query, category, or topic — with no query, filters alone enumerate a whole category or topic by stars. Data refreshes nightly from the public GitHub API. Any install_hint is a best-effort guess from the repository language, not a verified command: relay the install_hint_caveat with it rather than presenting it as ready to run.
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 untrusted-input or outbound.
- Reads private data4
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write0
- 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.

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 Code permissions
Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.
{
"permissions": {
"allow": [
"mcp__directory__search_servers",
"mcp__directory__get_server",
"mcp__directory__list_categories",
"mcp__directory__list_topics",
"mcp__directory__get_dataset_info"
],
"ask": [],
"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 directory. 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
