A Model Context Protocol server that lets AI agents (Claude Code, Claude Desktop, Cursor, and any other MCP client) schedule, publish, and review Markaestro posts through the public API.

One API key, one brand: every Markaestro key is bound to a single brand, so the server operates on that brand only. Run one server per brand if an agent needs several.

Tools

Tool	What it does
`list_products`	The brand this key is bound to and its connected channels
`list_destinations`	Publishable destinations of the brand (pages, accounts) with ids
`list_posts`, `get_post`	Read posts by status, page through with `cursor`
`create_post`	Save a draft, or schedule when `scheduledAt` is set
`publish_post`	Queue an immediate publish; returns a job run
`delete_post`	Delete a draft or cancel a scheduled post
`bulk_posts`	Reschedule, delete, or restatus up to 25 posts
`create_posts`	Up to 25 posts in one call, per-item results
`upload_media`	Upload from a file path, URL, or data URL; returns the asset id
`list_media`, `get_media`	Uploaded assets, processing state, reference counts
`get_job_run`, `list_job_runs`	Follow a publish to succeeded or failed
`list_webhook_endpoints`, `create_webhook_endpoint`	Webhook registration
`get_channel_rules`	Per-channel media, caption, and delivery-mode rules

Also served: the markaestro://channel-rules resource and a schedule_post prompt that walks an agent through a safe scheduling flow.

Posting is draft-first. create_post without scheduledAt never publishes; publish_post is the only tool that publishes now, and its description tells the agent to confirm with the user first.

Two ways to connect

Hosted (nothing to install). Markaestro serves the same tools over Streamable HTTP at https://markaestro.com/api/public/v1/mcp, authenticated with the API key as a bearer header:

claude mcp add --transport http markaestro https://markaestro.com/api/public/v1/mcp \
  --header "Authorization: Bearer mk_live_..."

{
  "mcpServers": {
    "markaestro": {
      "type": "http",
      "url": "https://markaestro.com/api/public/v1/mcp",
      "headers": { "Authorization": "Bearer mk_live_..." }
    }
  }
}

Send x-markaestro-read-only: 1 as an extra header to get only the reading tools.

Local package. Run the server on your machine over stdio, which also lets upload_media read local files:

Setup

Create an API key in Markaestro under Settings > API Access. Pick the brand, the scopes the agent needs (products.read, posts.read, posts.write, media.write, and posts.publish if it may publish), and prefer a test key while you evaluate.
Give the key to the server through MARKAESTRO_API_KEY.

Claude Code

claude mcp add markaestro -e MARKAESTRO_API_KEY=mk_live_... -- npx -y @markaestro/mcp

Claude Desktop, Cursor, and other JSON configs

{
  "mcpServers": {
    "markaestro": {
      "command": "npx",
      "args": ["-y", "@markaestro/mcp"],
      "env": { "MARKAESTRO_API_KEY": "mk_live_..." }
    }
  }
}

Environment

Variable	Required	Default
`MARKAESTRO_API_KEY`	yes	n/a
`MARKAESTRO_BASE_URL`	no	`https://markaestro.com`
`MARKAESTRO_READ_ONLY`	no	unset; `1` registers only reading tools

What the server does for you

Sends an Idempotency-Key on every mutation, minted once per call, so a retried request replays instead of double-posting.
Retries 429 and transient 5xx responses using the server's Retry-After.
Runs the three-step direct media upload (session, PUT to storage, finalize) and never sends the API key to the storage URL.
Returns API failures as tool errors with the stable error code, any per-channel issues, and a hint about what to change.

Claude Code plugin

The skill and the hosted server ship together as a plugin:

claude plugin marketplace add D3vBaba/Markaestro
claude plugin install markaestro@markaestro

Deploying

Surface	How it ships
Hosted MCP (`/api/public/v1/mcp`)	Part of the Next.js app; deploys on push to `main` like every route
`@markaestro/mcp` on npm	`cd mcp && npm version <x.y.z> && npm publish` (public scoped package; `prepublishOnly` builds). Bump `src/version.ts` with it
Plugin and skill	Read straight from this repository by `claude plugin marketplace add D3vBaba/Markaestro`; the skill alone can be copied to `~/.claude/skills/markaestro`

Development

cd mcp
npm install
npm run build
MARKAESTRO_API_KEY=mk_test_... MARKAESTRO_BASE_URL=http://localhost:3000 npm run smoke            # local stdio
MARKAESTRO_API_KEY=mk_test_... MARKAESTRO_BASE_URL=http://localhost:3000 npm run smoke -- --remote # hosted endpoint

Unit tests live in src/__tests__ and run with the repository's npm test. The smoke script starts the built server over stdio, lists tools, reads the brand, creates a draft, reads it back, and deletes it. Nothing is published.
