Overview

AI-generated overview

Postia lets an assistant draft, schedule and publish social posts to 18 networks, manage media and channel settings, and read channel analytics.

What you can do
  • Create, update, preview, duplicate and delete posts, and keep them as drafts until scheduled or published
  • Schedule, publish, unschedule, retry publication, take down posts and create or revoke share links
  • Upload media by base64 or URL, set alt text, reorder or remove media and covers, and browse cloud drives
  • Manage channels, channel sets, folders, hashtag sets, signatures, watermarks and relay rules
  • Read notifications, plan details, audience data and publishing statistics, and refresh analytics
When to use it
Useful when you want an assistant to prepare and push social content across many networks from one place, or to check how published posts and channels are performing without switching between platform dashboards.
Requirements
Remote MCP endpoint at mcp.postia.app over streamable HTTP. A Postia account with OAuth sign-in: the first connection opens the browser to sign in and press Allow. Analytics tools only work on plans that include analytics.
Before you install
The assistant can publish, schedule, take down and delete posts and revoke share links, which changes live content on connected networks. It can also change channel, signature, watermark and relay settings. Connected assistants are listed and can be disconnected in Postia account settings.

Installation

In SourceWeft

  1. Open Postia in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/app.postia%2Fpostia/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

Postia for Claude Code and Codex

Postia's MCP server is at https://mcp.postia.app. Sign-in is OAuth: the first time, the browser opens Postia, you sign in and press Allow. Connected assistants are listed, and can be disconnected, in Postia > Settings > Account > AI assistants.

Claude Code

bash
claude plugin marketplace add kvlkstudio/postia-ai-pluginsclaude plugin install postia@postia

Or the server alone, without the plugin's skill:

bash
claude mcp add --transport http postia https://mcp.postia.app

Then /mcp > postia > Authenticate.

Codex

bash
codex plugin marketplace add kvlkstudio/postia-ai-pluginscodex plugin add postia@postiacodex mcp login postia

Or the server alone:

bash
codex mcp add postia --url https://mcp.postia.appcodex mcp login postia

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
