Fezola requests the permissions Zernio's server announces for posts, accounts, analytics, ads, messaging, automations, commerce, calendar, files and campaigns. It never requests the Zernio permission that moves money. Tools can change on Zernio's side, so Fezola does not freeze them in a list. Keep your assistant's approval prompts on before it publishes.

When to choose Fezola

One social account, one assistant: Zernio's own MCP server, which you can connect directly, can be enough. Check Zernio's documentation for the current steps.
Several brands or clients: each Zernio account is its own source, and one assistant works across them.
The same connection in Claude and ChatGPT: one URL serves both. ChatGPT custom connectors are available on Business, Enterprise and Edu plans.
Nothing to install: Fezola is hosted, and you sign in with Zernio's authorization screen.
Social media next to the rest: mail, calendar, ad accounts and a shared Memory behind one connector.

Several accounts

Each Zernio account is a separate source, named, so an answer says which account it comes from. Example: "Show how last week's posts performed for each brand."

Questions to ask (example prompts)

“Schedule this post on LinkedIn and X for tomorrow at 9.”
“How did last week's posts perform?”
“List the social accounts connected to my Zernio account.”
“Show me the comments on my latest post.”
“Summarize the direct messages I received this week.”

A typical use

A small agency manages social accounts for two brands in Zernio. It asks: "Schedule this post for tomorrow at 9 on both brands' accounts, on the networks Zernio supports, then show last week's analytics for each." The assistant should confirm before scheduling, since a public post cannot be unsent. Example scenario, not a customer story.

Safety

A public post cannot be unsent, so your assistant should ask before it publishes. Fezola never requests the permission that moves money. What Zernio returns, such as a comment or a message, is treated as data, never as instructions. You can disconnect a Zernio account in Fezola and hide Zernio from an assistant with the tool ticks. Zernio sets its own pricing, so check its pricing page before connecting many accounts.
