planvortex-mcp

planvortex-mcp

The official Model Context Protocol server for PlanVortex. It lets an AI assistant — Claude Desktop, Claude Code, Cursor, VS Code — schedule posts, read the comment inbox and answer private messages across twelve social networks: Facebook, Instagram, Threads, LinkedIn, TikTok, X, WhatsApp, YouTube, Google Business, Bluesky, Discord and Telegram.

You need a PlanVortex app, and apps are part of the Custom plan. The server authenticates with a client_id and a client_secret that you create in the PlanVortex panel under Settings → Apps. On any other plan those credentials cannot be created, and this server has nothing to connect with.

Install

Nothing to install: your MCP client starts it with npx.

Claude Code

claude mcp add planvortex \
  --env PLANVORTEX_CLIENT_ID=... \
  --env PLANVORTEX_CLIENT_SECRET=... \
  -- npx -y planvortex-mcp

Then ask for something: "what do I have scheduled this week, and which comments are still unread?"

What it can do

Twenty-five tools, grouped by what they act on.

Group	Tools
Context	list_organizations, list_accounts, get_plan_use, get_unread_counts
Publishing	list_publications, get_publication, create_publication, update_publication, retry_publication
Media	upload_media
Comments	list_comments, get_comment_thread, reply_to_comment, hide_comment, mark_comment_read
Messages	list_conversations, list_messages, send_message
Numbers	get_dashboard_summary, get_publication_stats, get_top_publications, get_account_metrics
Catalog	get_social_limits, get_social_capabilities, create_connect_link

Plus three prompts — weekly_plan, inbox_triage, publish_from_brief — and four resources with the per-network limits, capabilities, comment matrix and your organizations.

Two things it deliberately cannot do

It never deletes anything. No tool removes a post, an account, a contact or a comment. This is not a switch you can turn on; the code is not there. The reason is in the security section below.

It cannot connect a social account. Connecting Instagram is an OAuth flow with a person clicking "authorize" on Meta's own screen, and an app with client credentials cannot do that — nobody's app can. create_connect_link returns a single-use link that expires in fifteen minutes; hand it to the user and let them open it.

Security

This server runs on your machine with your app's client_secret inside the process, and it feeds a language model text that members of the public wrote — comments, reviews, DMs — while that same model holds tools that publish under your brand.

That is a prompt-injection surface by construction, and it is worth knowing how it is handled:

• Every comment, review and incoming message arrives wrapped in an untrusted_content block with an explicit notice that it is data, not instructions. It is not a guarantee — no wrapper is — but it raises the bar.
• No destructive tools. If an injection succeeds, the worst case is a post you can see and delete, not four thousand deleted contacts.
• Third-party text never enters a tool description or a cached resource, where your client would not mark it as untrusted.
• Whether a publish is confirmed by a human is decided by your MCP client, not by this server. The tools declare the annotations that make clients show the warning; keep them on.

Set PLANVORTEX_MCP_READ_ONLY=1 to remove the nine write tools from the listing entirely — useful if you want to give an unsupervised agent read access and nothing else.

The --http mode

planvortex-mcp --http serves MCP over HTTP for a self-hosted deployment. The process holds your client_secret, so anything that can reach the port can publish to your accounts with a plain curl. Therefore:

• it binds to 127.0.0.1 by default;
• binding anywhere else requires PLANVORTEX_MCP_AUTH_TOKEN and the server refuses to start without it;
• the Origin header is validated on every request (DNS rebinding);
• TLS is your reverse proxy's job — put one in front;
• and a token from the request is never forwarded to PlanVortex. It authenticates against this process and stops here.

docker run --rm -p 127.0.0.1:3000:3000 \
  -e PLANVORTEX_CLIENT_ID=... -e PLANVORTEX_CLIENT_SECRET=... \
  -e PLANVORTEX_MCP_AUTH_TOKEN=$(openssl rand -hex 32) \
  planvortex-mcp --http --host 0.0.0.0

The flags are not optional there: the image speaks stdio by default, because that is what an MCP client starts (docker run -i planvortex-mcp) and what a server directory introspects. --http is the deployment mode, and you ask for it.

Environment variables

Variable	Required	What it does
PLANVORTEX_CLIENT_ID	yes	The app from your Custom plan.
PLANVORTEX_CLIENT_SECRET	yes	Its secret. Never passed as a tool argument.
PLANVORTEX_ORGANIZATION_ID	no	Default organization. Saves a discovery call per conversation.
PLANVORTEX_BASE_URL	no	Point at another PlanVortex deployment.
PLANVORTEX_MCP_UPLOAD_DIRS	no	Directories upload_media may read from. Empty means none.
PLANVORTEX_MCP_AUTH_TOKEN	with --http off-loopback	Bearer token the HTTP endpoint requires.
PLANVORTEX_MCP_READ_ONLY	no	1 removes the nine write tools.
PLANVORTEX_MCP_LOG_LEVEL	no	debug, info, warn, error, silent. Always to stderr.

Uploading media

With stdio the server runs on your machine, so upload_media accepts an absolute local path — but only inside PLANVORTEX_MCP_UPLOAD_DIRS, which is empty by default. Set it to the folders you actually want reachable:

PLANVORTEX_MCP_UPLOAD_DIRS=/Users/you/Pictures,/Users/you/Downloads

Reading an arbitrary path is exactly what an injected prompt would ask for, so there is no way to disable the allowlist. In --http mode a local path is refused outright: it would be a path on the server, not on your machine. Pass a public https URL there.

Which organization?

Almost everything in PlanVortex hangs off an organization. The server resolves it in three steps: the id_organization argument if the model passed one, then PLANVORTEX_ORGANIZATION_ID, and finally — only if your app reaches exactly one — that one. If it reaches several and nothing says which, the tool answers with the list of names and ids so the model can retry correctly, rather than failing with a bare error.

Development

npm install
npm test          # layers 1 and 2: no network, no credentials
npm run build
npm run inspector # MCP Inspector against the built server

Built on planvortex, the official Node client. This server speaks no HTTP of its own: every call goes through the library, which is where the error catalogue, the token cache, the multipart upload and the pagination already live.
