Anlyon alternative

9 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.

18 tools

Deletes or cancels 2Removes, cancels or revokes something.Claude Code: deny

assistants_archiveArchive (soft-delete) an assistant.No findings
Why it is in this group
- The name "assistants_archive" says "archive": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
Archive (soft-delete) an assistant.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: true
tools_deleteSoft-delete a custom tool.No findings
Why it is in this group
- The name "tools_delete" says "delete": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
Soft-delete a custom tool.
Annotations the server declares
- readOnlyHint: false

Changes things 7Creates or changes something that can be changed back.Claude Code: ask

assistable_connectOnly when you have no Assistable API key: start signing in.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.
Description, as the server wrote it
Only when you have no Assistable API key: start signing in. Returns verification_uri_complete and user_code; send the person that link (or the code) so they can sign in to Assistable, pick the account and approve. Then call assistable_connect_finish with device_code every interval seconds until it returns api_key. If they have no account, the link lets them sign up first.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: false
assistable_connect_finishCheck an assistable_connect sign-in.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.
Description, as the server wrote it
Check an assistable_connect sign-in. error.code authorization_pending means the person has not approved yet: wait interval seconds and call again. On approval it returns api_key once: use it as the Authorization: Bearer header for this MCP server (mcp_url) and keep it safe; it cannot be shown again.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: false
assistants_createCreate an assistant.No findings
Why it is in this group
- The name "assistants_create" says "create": a word for a change.
Description, as the server wrote it
Create an assistant. Required: subAccountId, name. Optional config blocks (llmConfig, voiceConfig, chatConfig) mirror the dashboard create dialog. voice_settings configures call greeting mode, opening messages, and voicemail behavior; platform_tools attaches platform-catalog tools (declarative full-replace — see the field description).
Annotations the server declares
- readOnlyHint: false
- destructiveHint: false
assistants_updatePatch an assistant.No findings
Why it is in this group
- The name "assistants_update" says "update": a word for a change.
Description, as the server wrote it
Patch an assistant. Only supplied fields change; nested config blocks are upserted. voice_settings updates call greeting mode, opening messages, and voicemail behavior; platform_tools declaratively replaces the attached platform-catalog tools (an empty array detaches all — see the field description).
Annotations the server declares
- readOnlyHint: false
- destructiveHint: false
calls_getFetch a call (status, recording, transcript) by ID.Reads text others write1 finding
Why it is in this group

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.

60 paths in this server alone from private data, through text someone else wrote, to a way out. Denying 2 outbound tools breaks every one.

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 assistable. Review it before you use it.
