Quick Start
Hosted Server (Recommended)
PostPulse runs a hosted MCP server at https://mcp.post-pulse.com — no setup required. Point your MCP client to this URL and authenticate via OAuth.
Example MCP client configuration:
{
"mcpServers": {
"postpulse": {
"url": "https://mcp.post-pulse.com"
}
}
}
Install via Smithery
You can also install through Smithery:
npx -y @smithery/cli install post-pulse/mcp-server --client claude
Self-Hosted
If you prefer to run the server yourself:
- Clone the repository:
git clone https://github.com/PostPulse/mcp-server-postpulse.git
cd mcp-server-postpulse
- Install dependencies and build:
npm install
npm run build
- Start the server:

Tools
list_accounts
List all connected social media accounts with their IDs, platforms, usernames, and display names. Use this as the first step to discover available accounts before scheduling posts or accessing chats.
Parameters: None
Returns: JSON array of account objects (id, platform, username, name, needsReauthorization). A new user has no accounts yet: the result is [] plus a hint to use connect_account. Accounts with needsReauthorization: true must be reconnected with connect_account before posting; the result names them in a second text block.
connect_account
Get a secure PostPulse link that connects (or reconnects) a social media account to PostPulse directly from the chat. The user opens the link in any browser and lands on a PostPulse page that shows which PostPulse account (masked email) the social account will be attached to. After Continue and approving access on the platform, the page says "Account connected — return to your chat". The tool does not wait for completion: once the user says they are done, call list_accounts to confirm the account.
Parameters:
| Name | Type | Required | Description |
|---|---|---|---|
platform | string | One of the two | INSTAGRAM, FACEBOOK, YOUTUBE, TIKTOK, THREADS, LINKEDIN, X_TWITTER, BLUE_SKY, TELEGRAM, PINTEREST |
accountId | number | One of the two | Reconnect an existing account (from list_accounts, usually one with needsReauthorization: true). The platform is taken from the account |
Behaviour:
- For a new connection the tool first checks that the user may add an account (plan or credits). If not, it returns the reason and a link to billing.
- The link is single-use, tied to the user's PostPulse account and valid for 24 hours; the platform consent starts only when the user clicks Continue on the page. It must not be shared: whoever completes it attaches their social account to this PostPulse account.
- If too many links are requested in a short time, the tool asks to wait a few minutes and try again.
- Telegram cannot be connected with a link: the tool returns instructions to connect it on https://post-pulse.com/app/accounts instead.
- A new Facebook connection creates one
FACEBOOK_PAGEaccount per picked Page: post to it directly, withoutlist_chats. ForTELEGRAMand for a reconnectedFACEBOOKaccount, calllist_chatsafterwards to pick the channel or Page. - Clients that support URL-mode elicitation additionally get a native "open this link" dialog; the link is always in the text result as well.
- Errors that happen in the browser (account limit, account already used by another PostPulse user, expired link) are shown on the page, not returned by the tool.
list_chats
List publishing destinations for accounts that have sub-destinations. Facebook accounts publish to Pages, Telegram accounts publish to channels or chats, and Pinterest accounts publish to boards. Call this before scheduling posts to these platforms — use the returned id as the facebookPageId, telegramChannelId or pinterestBoardId in schedule_post.
Only supports accounts whose platform is FACEBOOK, TELEGRAM or PINTEREST. Other platforms, including FACEBOOK_PAGE (an account that is one Page), do not have sub-destinations and should be posted to directly.
Parameters:
| Name | Type | Required | Description |
|---|---|---|---|
accountId | number | Yes | Account ID obtained from list_accounts |
Returns: JSON array of destination objects (id, title, type, platform).
upload_media
Upload media files (images, videos) for use in scheduled posts. Supports two modes: importing from a public URL (with automatic processing) or uploading binary data directly as base64. Returns a media key to reference in schedule_post.
Parameters:
| Name | Type | Required | Description |
|---|---|---|---|
mediaUrl | string | No | Public URL of the media file to import |
mediaData | string | No | Base64-encoded media file content |
mediaType | string | No | MIME type (e.g., image/jpeg, video/mp4). Required when using mediaData |
mediaName | string | No | Filename for the uploaded media |
Either mediaUrl or both mediaData and mediaType must be provided.
schedule_post
Schedule a social media post to one or more connected accounts. Supports platform-specific options like publication type (feed, reel, story), video titles, and topic tags. Posts are scheduled for a future time using ISO-8601 timestamps.
Parameters:
| Name | Type | Required | Description |
|---|---|---|---|
accountId | number | Yes | Account ID from list_accounts |
platform | string | Yes | Target platform: INSTAGRAM, FACEBOOK, TELEGRAM, YOUTUBE, TIKTOK, THREADS, LINKEDIN, PINTEREST, X_TWITTER, BLUE_SKY |

Resources
postpulse://accounts
An MCP resource providing the list of all connected social media accounts. Returns the same data as the list_accounts tool in JSON format, including needsReauthorization.
Authentication
This server uses OAuth 2.0 with Auth0. OAuth metadata is discoverable at /.well-known/oauth-protected-resource and /.well-known/oauth-authorization-server.
No existing PostPulse account is needed: signing in through the MCP client (with Google or a passwordless email code) creates the PostPulse account on first use. The user then connects social accounts with connect_account.
Dynamic Client Registration (DCR)
MCP clients that support OAuth can register automatically via Dynamic Client Registration (RFC 7591). The server advertises a registration_endpoint in its OAuth metadata, so compliant clients (such as Claude Desktop, Cursor, etc.) will handle the entire OAuth flow — registration, authorization, and token exchange — without any manual setup from the user.
Pre-Registered Client Credentials
If you already have client credentials created through the PostPulse Developer Portal, you can configure your MCP client to use them directly instead of DCR. Pass your client_id and client_secret in the OAuth authorization code flow against the PostPulse authorization server.
HTTP Endpoints
| Path | Purpose |
|---|---|
POST /, POST /sse | MCP Streamable HTTP transport (initialize + messages), Bearer token required |
GET /, GET /sse with Mcp-Session-Id | SSE stream for an existing session |
GET /, GET /sse with Accept: text/html | Minimal landing page for browsers and crawlers (links to the setup guide and API docs). Any other Accept without a session still gets 400 |
GET /health | Health check (ok) |
GET /robots.txt | User-agent: * / Disallow: / — the host is not a website |
GET /.well-known/* | OAuth metadata and the Smithery server card |
| anything else | 404 ({"error":"Not found"} or plain text for HTML clients) |
Every response carries X-Robots-Tag: noindex, nofollow so search engines never index this host.
Example Workflow
A typical interaction with the PostPulse MCP server:
- List accounts to find connected social media profiles
- Connect an account (if the platform is missing) with
connect_account - Upload media (optional) to prepare images or videos
- Schedule a post with content, media, and a future publish time
User: "Schedule an Instagram reel for tomorrow at 9am with the video at https://example.com/video.mp4 and caption 'Check this out!'"
First run (new user)
User: "Post 'Hello LinkedIn!' to my LinkedIn tomorrow at 10:00 UTC"
Assistant: list_accounts → [] ("No social accounts are connected yet")
connect_account(platform: LINKEDIN) → link
"Open this link, check the PostPulse account on the page, approve access on LinkedIn, then tell me when you are done."
User: "Done"
Assistant: list_accounts → [{ id: 123, platform: LINKEDIN, ... }]
schedule_post(accountId: 123, platform: LINKEDIN, content: "Hello LinkedIn!", scheduledTime: ...)
