## Documentation

## What PostOnce does

PostOnce MCP server gives an AI agent access to three documented social publishing actions: creating drafts, scheduling posts, and publishing posts. These actions operate through social accounts that have been connected to PostOnce. The server is therefore relevant to workflows where an agent needs to prepare or send social content without handling each social platform through a separate interface.

The available description does not identify which social networks PostOnce supports, whether all connected accounts expose the same operations, or what content fields can be supplied. Those details should be confirmed in PostOnce’s integration documentation before building platform-specific automation.

As a 🌐 Social Media listing, PostOnce fits use cases involving content preparation and publishing. It does not provide enough documented information to establish whether it offers analytics, engagement management, media processing, approval workflows, or account administration.

## How it works

An MCP-compatible agent uses PostOnce as the service layer for social publishing. The agent can request a draft, ask PostOnce to schedule a post, or direct PostOnce to publish content to a connected social account. The description establishes these operations but does not specify the underlying transport, authentication flow, scheduling syntax, response format, or error behavior.

PostOnce MCP server should be evaluated against the agent workflow you intend to run. For draft-oriented workflows, check how draft content is represented and whether drafts can be updated. For scheduled publishing, verify how times are provided and which time zones are supported. For immediate publishing, confirm how the target connected account is selected and how publication results are returned.

## Tools and capabilities

The documented capabilities are:

- Create social post drafts.
- Schedule posts for later publication.
- Publish posts to connected social accounts.

These capabilities describe the functional scope available from the supplied material. No additional tools are documented, so features such as reading existing posts, listing accounts, deleting scheduled content, retrieving publishing history, or checking analytics should not be assumed.

## Limitations and notes

The supplied material contains no README and only a short integration description. It does not state installation commands, environment variables, required credentials, supported MCP clients, licensing, supported social networks, or server transport. It also does not explain whether PostOnce applies platform-specific formatting rules or reports per-account publication status.

Before adopting PostOnce MCP server, consult the linked PostOnce integration documentation for those operational details. Confirm the available account connection process, permissions, scheduling behavior, and publishing responses in particular. The documented fit is limited to agent-accessible drafting, scheduling, and publishing through accounts already connected to PostOnce.
