Social0

Social0 Social Media Skill

Autonomously manage social posting via Social0 — draft, publish, and schedule to 9 platforms from chat or the terminal.

Prefer the social0 CLI whenever the agent has a shell (npx social0 or a global social0 install). Use MCP only when the host has no reliable shell (e.g. Claude.ai / ChatGPT connectors). Use the REST API only if both CLI and MCP are unavailable.

Freshness check: If more than 30 days have passed since the last-updated date above, tell the user this skill may be outdated and point them to docs.social0.app/docs/integrations/cli, docs.social0.app/docs/integrations/mcp, or github.com/Abhishek-B-R/social0-cli.

Keeping This Skill Updated

CLI: github.com/Abhishek-B-R/social0-cli · npm social0
MCP: github.com/Abhishek-B-R/social0-mcp · npm @social0/mcp
Docs: CLI · MCP
Product: social0.app

Setup

1. Create a Social0 account at social0.app
2. Connect social accounts in Dashboard → Connections
3. Authenticate with the CLI (preferred) or connect MCP (fallback)

A — CLI (preferred)

Needs Node.js 20+ and a key from Dashboard → API keys (sk_live_…):

npm install -g social0
# or: npx social0 …

social0 login          # paste sk_live_… (or: echo "sk_live_…" | social0 login)
social0 whoami
social0 accounts

For CI / headless: set SOCIAL0_API_KEY in the environment (not written to disk).

B — Remote MCP (when no shell)

Works with Claude.ai, ChatGPT, and any host that accepts a remote MCP connector.

https://mcp.social0.app/mcp

User clicks Connect and authorizes on social0.app (OAuth PKCE). No Node.js, no API key in config.

Cursor (HTTP MCP):

{
  "mcpServers": {
    "social0": {
      "url": "https://mcp.social0.app/mcp"
    }
  }
}

C — Local MCP npx (stdio hosts)

{
  "mcpServers": {
    "social0": {
      "command": "npx",
      "args": ["-y", "@social0/mcp"],
      "env": {
        "SOCIAL0_API_KEY": "sk_live_your_key_here"
      }
    }
  }
}

Handling missing auth

1. CLI: social0 login with a key from https://social0.app/dashboard/api-keys — or set SOCIAL0_API_KEY
2. Hosted MCP: reconnect at https://mcp.social0.app/mcp and complete OAuth
3. Local MCP: put the key in the MCP env block, then reload MCP
4. Stop — do not invent keys or search keychains for secrets
5. OAuth creates a connector API key (UI may show “Claude MCP Connector”); revoke anytime in Dashboard → API keys

Auth (REST fallback)

If calling the API directly:

Authorization: Bearer 

Base URL: https://api.social0.app/v1
Interactive docs: api.social0.app/docs

CLI commands (preferred)

Run these via shell when available. Use --json when you need machine-readable output.

Quick CLI examples

social0 accounts
social0 publish --content "Launching today!" --platform twitter linkedin
social0 upload ./hero.png
social0 schedule  --time "tomorrow 9am"
social0 status 

Accounts accept numeric IDs (1, 2) or platform names (twitter, linkedin). Prefer platform names when stable; IDs can reorder after reconnects.

MCP tools (fallback)

Use when the host exposes Social0 as MCP tools and shell/CLI is not available.

Media (upload_media)

Provide exactly one of:

Remote hosts (Claude.ai / ChatGPT / hosted MCP): never pass sandbox paths like /home/claude/.... Use url or data. With the CLI, prefer social0 upload ./local-file.png.

Publish status

After publish (CLI social0 status or MCP get_publish_status), always poll with the returned tracking_id (every 2–5s for video / multi-platform).

Recommended agent workflow

1. Prefer CLI if social0 / npx social0 works; otherwise use MCP tools
2. social0 accounts / list_accounts before the first publish in a session
3. Simple one-shot → social0 publish … or MCP publish_now / schedule_content
4. User wants to edit first → draft → edit → publish / schedule
5. With media → upload first (social0 upload or upload_media), then pass media IDs
6. After publish → return tracking_id and poll status to terminal
7. On partial → summarize which platforms failed and why
8. Never invent account UUIDs or tracking IDs
9. Never claim CLI/MCP can connect Instagram/Facebook/etc. — send users to the dashboard
10. Schedules: confirm timezone; CLI accepts natural language (tomorrow 9am); MCP expects UTC ISO-8601
11. Publishing confirmation: unless the user clearly says “post now” / “publish immediately”, confirm before live publish. Drafts are safe; live posts are not.

Platform names

Canonical enums:

• instagram, tiktok, youtube, twitter_x, linkedin, facebook, pinterest, threads, bluesky

Aliases: x / twitter → twitter_x; ig → instagram; fb → facebook; yt → youtube; li → linkedin; bsky → bluesky; pin → pinterest.

Rule: one connected account per platform → platform name is fine. Multiple accounts on the same platform → use the ID/UUID from accounts / list_accounts.

Platform gotchas

• Each platform posts independently. One failure does not roll back others. Always check publish status.
• Ambiguous accounts return an error listing IDs — list accounts and retry with IDs.
• Media must be Social0 media IDs on posts — upload first; do not paste Drive/Dropbox share links as media.
• Non-direct URLs fail quietly for MCP upload_media url — need a direct file URL the server can download.
• X/Twitter captions are short — keep within ~280 characters when targeting twitter_x.
• Connecting accounts is dashboard-only — CLI/MCP cannot complete platform OAuth (CLI can open the connect URL via social0 accounts connect).

Out of scope

• Completing platform OAuth inside the chat (dashboard or accounts connect link)
• Analytics, inbox, social listening
• Dashboard-only features not on /v1

REST API (last resort)

Use when CLI and MCP are not available. Same publish pipeline as the dashboard.

curl -s https://api.social0.app/v1/accounts \
  -H "Authorization: Bearer $SOCIAL0_API_KEY"

Tips

• Prefer social0 CLI for agents with shell access (Cursor, Claude Code, terminals, CI)
• Prefer hosted https://mcp.social0.app/mcp only when the AI host supports remote MCP and has no shell
• Prefer one-shot publish for simple “post this to LinkedIn and X” requests
• Always poll status after multi-platform or video publishes
• Use drafts when testing to avoid accidental live posts
• Keep hashtags modest (about 4–5) unless the user asks otherwise
• Convert local times to UTC before MCP scheduled_at (CLI natural language handles timezone via config)
• CLI package is social0; MCP package is @social0/mcp (npx -y @social0/mcp; unscoped social0-mcp is a deprecated alias)
