Anlyon alternative

2 of these tools change something. Run those 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.

nymrel_audit_websiteAudit one public website for SEO, schema, and AI discoverability.Reads text others writeCan send data outNo 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.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
- outboundThe input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
Description, as the server wrote it
Audit one public website for SEO, schema, and AI discoverability. Returns the score, grade, discoverability status, detected schema types and recommendations supplied by the audit. Results may contain only an aggregate summary; additional per-check evidence may be included. Report robots.txt, sitemap.xml, llms.txt or AI-crawler checks only when their evidence is present in the result; absent checks are unreported, not proven by an aggregate score or PASS. Preserve unmeasured checks and empty recommendations without inventing findings. This is not a ranking guarantee or a security, legal-compliance or crawler-access certification.
Annotations the server declares
- title: Audit website discoverability
- readOnlyHint: true
- destructiveHint: false
- openWorldHint: true
nymrel_social_clip_scoreMeasure what the opening of a short-video transcript actually does.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
Measure what the opening of a short-video transcript actually does. Returns each measured signal - opening word count, whether it opens on a hook pattern, whether it addresses the viewer, curiosity signals, whether the total word count sits in the platform's range - plus `hook_score`, a 0-100 rollup of exactly those signals, and suggested edits. `target_platform` accepts `tiktok`, `instagram_reels`, `youtube_shorts`, or `x`. The `reels` and `shorts` aliases normalize to their corresponding canonical IDs, which the result echoes. Every figure describes the text the caller supplied. This does not estimate reach, views, retention or virality; those are outcomes in the world that this tool never observes. Read `signals` to see what moved the score.
Annotations the server declares
- title: Measure a short-video hook
- readOnlyHint: true
- destructiveHint: false
- openWorldHint: false

nymrel_find_domainSuggest domain names and check each one against public registry records.Reads text others writeNo findings
Why it is in this group
- The name "nymrel_find_domain" says "find": a word for reading.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it
Suggest domain names and check each one against public registry records. A name is only reported available when the registry clearly says it is free. When the lookup is inconclusive `availability_checked` is false and `available` is false, so read that as "not confirmed free" rather than "already taken" - some TLDs have no registry service to ask. Confirm at a registrar before buying. `brandability_score` is an opinion about the string, not a claim about how the name will perform; `brandability_factors` reports what it was computed from so you can weigh it yourself.
Annotations the server declares
- title: Find domain names
- readOnlyHint: true
- destructiveHint: false
- openWorldHint: true
nymrel_golf_bag_gapAnalyse carry-distance gaps for a structured list of golf clubs.No findings
Why it is in this group
- The description's first verb is "analyse": a word for reading.
Description, as the server wrote it
Analyse carry-distance gaps for a structured list of golf clubs. Every club needs a ``name`` and its measured ``carry_distance_yards``; ``loft_degrees`` is optional. Pass 1 to 14 clubs with unique names. The upstream rejects any other key, so send only these three.
Annotations the server declares
- title: Analyse golf bag gaps
- readOnlyHint: true
- destructiveHint: false
- openWorldHint: false
nymrel_remote_get_file_infoUse this when the user explicitly wants Nymrel Remote to return metadata for a file or directory.Reads private dataNo findings
Why it is in this group
- The name "nymrel_remote_get_file_info" says "get": a word for reading.
What it can reach
- private-dataThe name "nymrel_remote_get_file_info" says "get" and "file": it reads files.
- private-dataThe description's first sentence says "file": it reads files.
Description, as the server wrote it
Use this when the user explicitly wants Nymrel Remote to return metadata for a file or directory. Select the target with the optional device argument.
Annotations the server declares
- title: get file info
- readOnlyHint: true
- destructiveHint: false
- openWorldHint: false
nymrel_remote_get_read_resultRetrieve the result of your pending Nymrel Remote read using its callId.No findings
Why it is in this group
- The name "nymrel_remote_get_read_result" says "get": a word for reading.
Description, as the server wrote it
Retrieve the result of your pending Nymrel Remote read using its callId. If a file inspection returns pending, use this tool instead of submitting that inspection again. It never starts a new device operation. If still pending, wait briefly before checking again.
Annotations the server declares
- title: Get remote read result

- 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.

10 paths in this server alone from private data, through text someone else wrote, to a way out. Denying 1 outbound tool breaks every one.

Reads private data5: Reads files, mail, messages, databases, secrets, calendars or repositories.; nymrel_remote_get_file_info
nymrel_remote_list_directory
nymrel_remote_read_file
nymrel_remote_search_content
nymrel_remote_search_files
Reads text others write2: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; nymrel_audit_website
nymrel_find_domain
Can send data out1: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.; nymrel_audit_website

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.

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 nymrel. Review it before you use it.
