--- title: "Muse + Posty: schedule posts via MCP | Posty" description: "Schedule posts to 12+ social platforms from Meta Muse Code through MCP. Write the announcement where you write the code." canonical: https://posty.hu/en/ai/muse source: https://posty.hu/en/ai/muse.md --- ![Muse](https://posty.hu/icons/ai/muse.svg) Muse and Posty # Muse schedules where the code is written Muse writes the release announcement in the coding session, and Posty schedules it. You do not have to switch to another tool. [Get started](https://posty.hu/regisztracio)[How to connect](#igy-mukodik) Paste this to Muse: Install the Posty CLI: npm install -g posty-cli, then log in: posty auth:login. The package SKILL.md file describes every command, details: https://posty.hu/ai/muse First steps ## The CLI in four commands You install the CLI, sign in, fetch your integrations, then create a post. After that your release script can take over. terminal ``` # Install the Posty CLI package $ npm install -g posty-cli # Sign in to your Posty account $ posty auth:login # Fetch your integrations $ posty integrations:list [{ "id": "cmf3k7…", "name": "Cafe · Instagram" }] # Create and schedule the post $ posty posts:create \ $ -c "New brunch menu this Saturday." \ $ -i "cmf3k7…" \ $ -s "2026-08-16 09:00" --timezone Europe/Budapest ✅ Post created successfully! { "id": "cmf7p2…", "state": "QUEUE" } ``` The CLI writes JSON to stdout, and status and errors to stderr. On failure it exits with a non-zero code. ### A thread, in a single command terminal ``` $ posty posts:create \ $ -c "We shipped 2.0. Three things changed. 1/3" \ $ -c "The calendar is faster. 2/3" \ $ -c "And there is a dark theme at last. 3/3" \ $ -d 5 \ $ -i "cmf3k7…" \ $ -s "2026-08-16T09:00:00+02:00" ``` Muse session ## From code to a scheduled post The announcement and the release are made in one place. You reach Posty over MCP, the CLI, or the REST API. ### Post from the session Muse writes the announcement in the coding session, then schedules it through Posty. The release and the post are made in one place. ### Uploading media You upload the media file first with the posty upload command. The URL you get back goes as the -m value after the post's -c flag. ### A calendar you can read and rearrange Muse reads the posts on the calendar, finds free slots, and rearranges the plan. That way it does not schedule the release post blindly. ### CLI as another way If you need a command instead of MCP, the published posty-cli reaches the same account. posty posts:create also runs from a release script and from CI. ### Public REST API The third way is the public REST API at api.posty.hu. You can reach the same Posty account from your own integration or automation too. ### Approval in the calendar Muse writes and schedules the post, and you review it in the Posty calendar. You can approve the copy and the time before it goes out. How it connects ## Four steps to Muse You set up the accounts and the key. After that, Muse hands the scheduling to Posty from the same session. 1 ### Connect your accounts On the Posty web app, you connect the social accounts you want to use through OAuth. You only have to do this once. After that, Muse can reach the Posty integrations for those accounts. OAuth on the Posty web app terminal ``` $ posty integrations:list [ { "id": "cmf3k7…", "name": "Cafe · Instagram" }, { "id": "cmf3k9…", "name": "Cafe · Facebook" } ] ``` 2 ### Create a key Open Settings → Developers and create a key that starts with psty\_mcp\_…. You also get the full ready-made config block for Muse here. Key and ready-made Muse block .env ``` # Settings → Developers → New key # We show the key once, when you create it. # For the command line and the REST API: POSTY_API_KEY=AZ_API_KULCSOD # MCP clients get a separate key: # psty_mcp_… ``` 3 ### Hand it to Muse Paste the Posty block under the mcp\_servers key in ~/.config/muse/settings.json, with streamable\_http transport. Keep schema\_version in the file: without it, Muse silently skips the file. Required fields in settings.json ~/.config/muse/settings.json ``` { "schema_version": 1, "mcp_servers": { "posty": { "transport": "streamable_http", "url": "https://api.posty.hu/mcp/AZ_API_KULCSOD" } } } ``` 4 ### Review the schedule Muse writes the announcement, and Posty schedules it. Before it goes out, you review and approve the copy, the platforms, and the time in the Posty calendar. Review in the Posty calendar terminal ``` $ posty posts:list [ { "id": "cmf7p2…", "state": "QUEUE", "publishDate": "2026-08-16T07:00:00Z" }, { "id": "cmf7q8…", "state": "DRAFT", "publishDate": "2026-08-18T06:30:00Z" } ] ``` ![Muse](https://posty.hu/icons/ai/muse.svg) In short ## What is Muse? Muse, full name Meta Muse Code, is a coding agent. You work with it in the same session where the code is written. It connects to Posty as an MCP client, so you can write and schedule the release announcement in the same place. You finish the release, then ask for the matching post in the same Muse session. Muse writes it, and Posty schedules it. You do not have to switch tools, or start over in a separate UI. Muse connects through its config file: the Posty MCP block goes under mcp\_servers, with streamable\_http transport and the schema\_version field. You get the ready-made block on the Settings → Developers page. ### Writes next to the code Muse writes the release post next to the code. The announcement is written in the same session as the release. ### Connects over MCP The Posty MCP server receives the Muse request, then schedules the post to the given social account. The service URL is https://api.posty.hu/mcp. ### Your own model writes Muse writes the copy, not Posty. Posty has no built-in AI writer, on purpose, so you use your own model. Built for agents ## A predictable interface for Muse Posty responses and errors are easy to parse. You reach the same account three ways. - Machine-readable JSON Command JSON output is easy to parse, so Muse does not have to pull data out of human-readable text. - Clear error signals The CLI writes status and errors to stderr, and on failure it exits with a non-zero code. - Built-in skill file The SKILL.md in the npm package teaches the agent how to use the CLI, with no extra training. - Flat command set A single flat command set handles posts, integrations, analytics, uploads, settings and login, with no hidden state. - Three ways in You reach the same Posty account over MCP, the published CLI, and the public REST API. SKILL.md ``` --- name: posty description: Posty schedules and publishes social posts from the command line. homepage: https://posty.hu --- # Output contract Every command prints its JSON result — and nothing else — to stdout; status lines, warnings and errors go to stderr, and every failure exits 1. # Two Hard Rules (Read First) Rule 1 — Authenticate before anything. Rule 2 — Every file passed to `-m` MUST first go through `posty upload`. ``` SKILL.md is part of the npm package. The agent can read it directly and learn the Posty CLI from it. See how Posty connects to the other agents, and pick the path that fits your workflow.

Posts `posty posts:create`New post: scheduled, as a draft, or published right away. `posty posts:list`Posts in the given period. You can filter by client group too. `posty posts:delete `Delete a post by id. `posty posts:find-slot `The next free publishing time for a social account. `posty posts:status `Switch a post between draft and scheduled. `posty posts:missing `Content already on the platform for a post with a missing id. `posty posts:connect `Connect a post to content that is already published. Social accounts `posty integrations:list`Connected social accounts and their ids. This is what the -i flag needs. `posty integrations:groups`The list of client groups, if you work with more than one brand. `posty integrations:settings `An account's settings schema, rules, length limit, and tools. `posty integrations:trigger `Call a platform tool for extra data, for example to search for music. Media and analytics `posty upload `Upload a media file. The URL you get back goes into the posts:create -m flag. `posty analytics:platform `A social account's stats going back the given number of days. `posty analytics:post `Performance of a single post. Login and settings `posty auth:login`Log in with OAuth2 device authorization: the browser opens, you approve. `posty auth:logout`Clear stored login data. `posty auth:status`Shows whether you're logged in, and checks access too. `posty config:set <érték>`Save a CLI setting, for example the default timezone. `posty config:get [kulcs]`Print the saved settings. posts:create flags `-c, --content`The post text. Repeat it to make a thread: the first is the post, the rest are comments. `-m, --media`Media for the -c that comes before it. The URL has to come from posty upload. `-i, --integrations`Ids of the target social accounts, comma-separated. `--date, -s`When to publish. Either with an explicit offset, or together with the --timezone flag. `--timezone`IANA timezone name, for example Europe/Budapest. Only pass a date with no offset together with this. `-t, --type`schedule (default), draft, or now. `-d, --delay`Delay in MINUTES between items in the thread. `--json`The full post description from a JSON file, when the flags are not enough. `--settings`Platform-specific settings as JSON. The schema comes from integrations:settings. The CLI writes JSON to stdout, and status and errors to stderr. On failure it exits with a non-zero code.

Check that the Posty block is under the mcp\_servers key in ~/.config/muse/settings.json, and that transport is set to streamable\_http. Keep the schema\_version field too. Without it, Muse silently skips the file. #### Does Muse write the post, or Posty? Muse writes the copy in the coding session. Posty schedules and handles it. Posty has no AI writer, on purpose, so you use your own model. #### Can I review the post before it is published? Yes. Muse schedules the announcement, and you approve the copy, the platforms, and the time in the Posty calendar before it goes out. #### How does media get into the post? You upload the media file with the posty upload command. The URL you get back goes into the -m value, right next to the -c content the media belongs to. #### Can I use Posty from a release script or CI? Yes. posty posts:create runs from a release script and from CI, and POSTY\_API\_KEY can come from the environment. You install the CLI with npm install -g posty-cli; the command name is posty. #### Which plans include MCP, the CLI and the REST API? All three are available on the Pro, Kreátor and Csapat plans. Posty handles 12+ platforms, including Facebook, Instagram, TikTok, LinkedIn, X and YouTube. Get started today ## Write it where you ship it.
