# Claude Code MCP: Publish Social Posts From the Terminal **Source:** https://posteverywhere.ai/connectors/claude-code --- # Publish social posts straight from Claude Code Yes, and it is the fastest of the lot. One terminal command, then authenticate. There is no config file to hand-edit. Claude Code takes one command. No JSON to hand-edit, no restart, no path to get wrong. Run the add command, authenticate once, and the 38 tools are available in every session. The only flag that matters is --scope user. Leave it out and the server binds to whichever folder you happened to be in, which is why people run the command successfully and then find /mcp completely empty in the next project. Because the server is registered at user scope it is available in every session and every repository, not just the one you happened to be in. That is the difference between a tool you use once and one that becomes part of how you ship.

Before you start - The Claude Code CLI installed and authenticated. - A PostEverywhere plan for the account the browser sign-in will attach to. - A browser available for the one-time authentication step, which is why this suits interactive sessions rather than CI. Run this once`claude mcp add --scope user --transport http posteverywhere https://mcp.posteverywhere.ai` - 1Run the command above in your terminal. - 2Type /mcp in Claude Code and choose Authenticate. Your browser opens, sign in, done. **Worth knowing:** The --scope user flag matters. Without it the server is tied to the folder you ran the command in, and /mcp shows nothing anywhere else.

See [the Claude Code config reference](https://posteverywhere.ai/docs/integrations/mcp#connect-the-mcp-server-to-claude-code). ## What you can ask Claude Code once it is connected Claude Code is the one to reach for when publishing should be a step in a script rather than a separate errand. Each one maps onto a real tool, covering scheduling, [AI captions](https://posteverywhere.ai/ai-content-generator) and [analytics](https://posteverywhere.ai/social-media-analytics). The [AI agents page](https://posteverywhere.ai/agents) has the full surface. Publish a release announcement as the last step of a deploy script Pipe a changelog straight into scheduled posts across every account Write a week of build-in-public updates in one session Query what is scheduled and reschedule it without leaving the terminal Retry every failed post in a loop, no browser involved Generate captions and images, then schedule the result, in a single run Thirty-three tools become available in every session. Because it is a terminal client, they compose with everything else you run there, so a release script can end by scheduling the post that announces it. ### What the tools cover All 38 tools are available, which matters more in a terminal than a browser because they compose. Scheduling, media upload, campaigns, analytics and account health can each be a step in a longer script, so a release process can check account health, draft from the changelog, schedule the post and report back without a single manual action in between. ### Prompts that work, and what comes back “Read CHANGELOG.md, write a release post from the top entry, and schedule it for 9am tomorrow.” Claude Code reads the file from disk, drafts from the newest entry and queues the post, all without leaving the terminal. “Schedule a build-in-public update for every weekday next week from these five bullet points.” It writes five distinct posts and spaces them across the week rather than dumping them into one slot. “Anything fail to publish overnight? Retry it and tell me why it failed.” It reads delivery status, retries what it can, and reports the actual platform error rather than a generic failure. ## Claude Code MCP troubleshooting The three things that actually go wrong, and what fixes each one. /mcp shows nothing after the command succeeded The --scope user flag was missing. Without it the server binds to the working directory, so it is invisible everywhere else. Re-run the command with the flag. The browser opens but authentication never completes Finish the sign-in in the same browser profile you are already logged into PostEverywhere with. A different profile starts a fresh session and the callback has nothing to attach to. claude: command not found The Claude Code CLI is not installed or is not on your PATH. Install it first; the MCP command is part of that CLI rather than a separate tool. ## What it will not do Worth knowing now rather than after you have started a trial. - It is not suitable for headless automation. The sign-in needs a browser once, so for CI the REST API with a Bearer key is the right tool. - The registration is per user, not per repository. That is usually what you want, but it means a teammate has to run the command themselves. - It does not monitor anything. Scheduling and reporting happen when you ask, not on a loop. ## When to use Claude Code rather than a browser client Claude Code is the one to reach for when publishing should be scriptable. If the announcement belongs at the end of a deploy rather than in a browser tab, this is the shortest path to it. Reference material: [Claude Code MCP documentation](https://docs.claude.com/en/docs/claude-code/mcp), [The Model Context Protocol spec](https://modelcontextprotocol.io). The full agent surface, including the REST API, is on the [AI agents page](https://posteverywhere.ai/agents). ## Included on every paid plan from $9/mo One key covers Claude Code, the REST API and the SDK.

Then: Type /mcp in Claude Code and choose Authenticate. Your browser opens, sign in, done. There is no plan restriction on this client. ### Can Claude Code post to social media? Yes, and it is the fastest of the lot. One terminal command, then authenticate. There is no config file to hand-edit. Claude Code is the one to reach for when publishing should be a step in a script rather than a separate errand. ### Why does /mcp show nothing after I ran the command? Almost always the missing --scope user flag. Without it the server binds to the directory you were in when you ran the command, so it is invisible in every other project. Re-run with the flag and it is available everywhere. ### Do I need to edit a config file? No. The claude mcp add command writes the configuration for you. There is no JSON to hand-edit, no path to get wrong and no restart needed. ### Can I use this in a non-interactive script? For scripted or CI use the REST API is the better fit, since it authenticates with a Bearer key and needs no browser step. The MCP server is built for an interactive session where you approve the sign-in once. ### What does it cost to use Claude Code this way? One key covers Claude Code, the REST API and the SDK. No developer tier, no enterprise call. Every plan has a 7-day trial and a card is required to start it. ## Other assistants [Claude](https://posteverywhere.ai/connectors/claude)[ChatGPT](https://posteverywhere.ai/connectors/chatgpt)[Cursor](https://posteverywhere.ai/connectors/cursor)[Grok](https://posteverywhere.ai/connectors/grok)[Windsurf](https://posteverywhere.ai/connectors/windsurf)[Cline](https://posteverywhere.ai/connectors/cline)[Zed](https://posteverywhere.ai/connectors/zed)[Codex CLI](https://posteverywhere.ai/connectors/codex-cli)
