Question 1

Which n8n node connects to PosteAhora?

Accepted Answer

The MCP Client Tool, a built-in sub-node you attach to an AI Agent's Tool connector; on the canvas it shows up as MCP Client. Set the Endpoint to https://mcp.posteahora.com/mcp with Server Transport on HTTP Streamable, then choose under Tools to Include whether the agent gets All tools, only the Selected ones, or All Except a few. It ships with n8n, so it works on n8n Cloud and self-hosted alike, with nothing to install.

Question 2

Which credential should I use: Bearer, OAuth2 or a connector URL?

Accepted Answer

For a workflow that runs unattended, Bearer Auth with a pah_live_ API key from the API page: it does not expire, it is bound to one workspace, and you revoke it there if it leaks. The MCP OAuth2 option works too — n8n registers itself with our server and you sign in once in the credential — but a sign-in lasts at most 90 days before you reconnect it, and the redirect URL of your n8n must be https or localhost. A personal connector URL with Authentication set to None also works; the secret is in the URL, so treat it like a password.

Question 3

Can I call PosteAhora without an AI Agent in the loop?

Accepted Answer

Yes, three ways. An HTTP Request node (Generic Credential Type → Bearer Auth) reaches the whole REST API at https://api.posteahora.com/functions/v1/api, including per-network captions and options. The standalone MCP Client node calls one PosteAhora tool per node with no model. Our community node n8n-nodes-posteahora covers the basics — accounts, posts, ideas, analytics — but it is unverified, so it installs only on self-hosted n8n, by an Owner or Admin, and it cannot post to Pinterest or YouTube.

Question 4

Does self-hosting n8n change anything?

Accepted Answer

The workflow and the credential stay on your instance, and it needs no inbound port open for PosteAhora, so it works behind a firewall. What leaves it is the outbound HTTPS call to our connector or API, plus whatever the AI Agent sends to its model provider, unless you run a local model.

Question 5

Will an unattended workflow publish something nobody checked?

Accepted Answer

It can, if it has a tool that publishes: publish_post_now does, and so does create_post with status published. Set Tools to Include to Selected and give the agent schedule_post plus the read tools, leaving out create_post, publish_post_now and delete_post; scheduled posts wait in your PosteAhora queue, where you can edit or delete them before they go out. With HTTP Request, send status scheduled, not published. Posting is asynchronous; get_post_status tells the workflow how each network went.

Question 6

Can the workflow attach media it generated?

Accepted Answer

Yes, by URL. Pass a publicly reachable link to media_import_url (or POST /media/import-url from an HTTP Request node) and PosteAhora fetches it on its side. A file that exists only on the n8n host is not reachable from our servers — put it somewhere addressable first, or upload it in PosteAhora.

Question 7

What does it cost?

Accepted Answer

n8n's self-hosted Community Edition is free, n8n Cloud is billed by n8n, and the model behind the AI Agent is billed by its provider. On our side there is a 7-day trial for $0 with a card on file, then a flat monthly or yearly price by plan, with the connector and API included on every plan. Every plan has unlimited posts; what varies is how many social accounts you can connect.
