Use PostEverywhere from Claude Code and other coding agents

Run npx @posteverywhere/cli connect in your terminal. It finds the coding agents on your computer and connects them to PostEverywhere's hosted MCP server at https://mcp.posteverywhere.ai. You then sign in once inside each agent.

Steps#

1. Open a terminal and run:

   npx @posteverywhere/cli connect
   

2. Tick the agents you want in the checklist. Agents found on your computer are ticked already.
3. Finish the sign-in inside each agent:
   • Claude Code: run /mcp, pick posteverywhere, choose Authenticate.
   • Codex CLI: the login opens your browser. Sign in and approve.
   • Gemini CLI: run /mcp auth posteverywhere.
   • Cursor and Windsurf: restart the app and sign in when asked.
   • Cline: click Authenticate under MCP Servers.
   • Zed: sign in when Zed asks.
4. Ask the agent something, for example "schedule a post to all my accounts for tomorrow at 9am".

No API key is written to disk. Config files are merged, never overwritten, and a backup copy is made before the first change.

Add it by hand#

If you prefer, add the server yourself:

• Claude Code: claude mcp add --scope user --transport http posteverywhere https://mcp.posteverywhere.ai
• Claude Desktop: Settings, Connectors, Add custom connector, paste https://mcp.posteverywhere.ai.
• Cursor: the Agents page in the app has an Add to Cursor button and a JSON snippet for ~/.cursor/mcp.json.
• Codex CLI: codex mcp add posteverywhere --url https://mcp.posteverywhere.ai, then codex mcp login posteverywhere.

The Agents page (app.posteverywhere.ai/agents) has the steps for every agent, with copy buttons.

Teach the agent the CLI#

Agents that can run shell commands can also use the CLI directly. Install the skill:

npx skills add posteverywhere/cli

Claude Code users can add it as a plugin instead, which brings auto-updates:

claude plugin marketplace add posteverywhere/cli

The agent then knows every command: connecting accounts, checking per-platform limits, scheduling, and reading back per-destination results.

Example requests#

• "Show me my connected social accounts"
• "Draft three posts about our launch but don't schedule them. I want to review first"
• "Show my drafts, then schedule the second one for Tuesday at 9am"
• "Show my recent posts and their status"
• "Retry the failed post"

Ask for drafts when you want to check posts before they go out. A draft is not published until you or the agent schedules it.

Headless use (CI or a server)#

Set a key instead of signing in:

export POSTEVERYWHERE_API_KEY=pe_live_...

Create the key on the Developers page, API Keys tab. See Getting an API key.
