Publish or schedule social posts, inspect delivery, and manage automatic crossposting through a connected PostOnce MCP server. Use when the user wants to send content to their PostOnce accounts or configure a PostOnce workflow.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# PostOnce

Use the connected PostOnce tools for the user's requested publishing or crossposting task. This skill supplies workflow guidance; installing it does not connect an account or grant access.

Requires a configured PostOnce MCP connection and account access. Local media upload also requires a client capable of reading the file and making an HTTP upload.

## Connect and discover

If PostOnce tools are missing, use the client's setup at [PostOnce integrations](https://postonce.to/integrations). The hosted endpoint is `https://postonce.to/mcp` (Streamable HTTP). Follow the currently supported authentication route for that client. Keep credentials in the client's private connection settings or secret environment; never ask for a key in chat.

1. Inspect the available tools and their current input schemas. Clients may prefix names with the server name; the names below identify the PostOnce operation.

How to install

The exact contents, by fingerprint

mdr add postoncehq/tiktok-mcp/postonce@sha256:24b039bc9583f2c1

The line at the top of this page pins the label v0.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
