AI-powered social media management for agents
Add one MCP server to Claude, ChatGPT, Cursor or VS Code. Your agent can then draft, schedule and review posts on 15 channels and read the analytics. You approve the connection once with your PostBoost sign-in.
Free plan: 3 social accounts, no credit card. MCP and API on every plan.
Read the MCP docsYour agent walks you through signup, the connection and a first draft. It asks before it does anything you have to approve.
Set up PostBoost (https://postboost.co) so you can help me with social media.
1. If I do not have a PostBoost account yet, send me to https://postboost.co/app/register and wait until I say I have signed up.
2. Add the PostBoost MCP server to this client: https://postboost.co/mcp
It uses OAuth sign-in, so give me the login link and wait until I approve it.
If you cannot add servers yourself, tell me exactly where to add it in this client.
3. Then list my connected social accounts in PostBoost.
If none are connected, use the create-connect-link tool to give me a link for each network I want, and wait.
4. Write one short post for one of my accounts and save it as a draft. Do not schedule or publish anything until I say so.
Setup help for each client: https://postboost.co/agents.mdPrefer to set it up yourself? Pick your client below.
Claude.ai
Open Settings, then Connectors, then Add custom connector.
Name: PostBoost. URL:
https://postboost.co/mcpClick Add, then Connect, and approve the connection on the PostBoost sign-in screen.
ChatGPT
Open Plugins in ChatGPT, click +, then choose Add custom MCP server.
Name: PostBoost. Server URL:
https://postboost.co/mcpAuthentication: OAuth, then confirm the risk warning (I understand and want to continue).
Select Create as a plugin, install it, and approve the connection on the PostBoost sign-in screen.
In a chat, type @ and pick PostBoost. ChatGPT asks you to confirm before write actions.
Claude Code
Run:
claude mcp add --transport http --scope user postboost https://postboost.co/mcpThen run /mcp in Claude Code and choose Authenticate next to postboost.
Running headless, for example in CI? Add --header "Authorization: Bearer YOUR_API_TOKEN" and skip the sign-in.
Cursor
Or add this to .cursor/mcp.json in your project, or ~/.cursor/mcp.json for every project:
{
"mcpServers": {
"postboost": {
"url": "https://postboost.co/mcp"
}
}
}Cursor opens the sign-in when you first turn the server on.
Full guideVS Code
Add this to .vscode/mcp.json:
{
"servers": {
"postboost": {
"type": "http",
"url": "https://postboost.co/mcp"
}
}
}Other MCP clients
Any client that supports remote MCP servers over Streamable HTTP with OAuth can use this URL:
https://postboost.co/mcpIf your client cannot run an OAuth sign-in, send an access token instead (next tab).
API token
Create a token in the dashboard: click your avatar in the top bar and choose Access Tokens. It is shown once.
The connector accepts the token as a header:
Authorization: Bearer YOUR_API_TOKENWant one tool per API operation? Use the advanced server:
https://postboost.co/mcp/postboostCodex:
[mcp_servers.postboost]
url = "https://postboost.co/mcp/postboost"
bearer_token_env_var = "POSTBOOST_API_TOKEN"Gemini CLI:
gemini mcp add --transport http --header "Authorization: Bearer YOUR_API_TOKEN" postboost https://postboost.co/mcp/postboostNever paste a real token into a shared file. Read it from an environment variable such as POSTBOOST_API_TOKEN.
The same posts, calendar and accounts your team sees in the dashboard.
Generated from the connector itself, so this list is always current.

list-posts
List posts in a workspace, most recent first.

List the tags defined in a workspace.
list-media
List the media files (images, GIFs and videos) in a workspace's library, newest first.
get-media-upload-status

get-account-analytics
Get the analytics of one connected account for a period.
get-post-analytics
Get the analytics of a published post by its uuid: totals of views, likes, comments and shares across every account it was published to, their trend over time, engagement rate, breakdown, reach-to-engagement funnel and peak day, plus the same figures per account (by numeric account id) with the provider's own metrics and how the post compares with that account's average.
get-best-posting-times
Get the best times to post, learned from how past posts of the chosen accounts performed.
validate-post
Checks a post exactly as create-post would, without creating anything: content rules per network, per-network requirements, duplicate guard, per-account daily caps, account authorization and the X monthly allowance (when enforced).
get-account-health
Pre-flight check before publishing: for every connected account whether it is authorized, still holds a token, and how much of its daily posting cap is used today; plus the workspace's X (Twitter) posts this month against its monthly allowance.
get-ai-credits
The workspace's AI credits: text credits used, limit and remaining in the current billing cycle, and image credits for the current calendar month (UTC).
get-brand-voice
The workspace's brand voice: business name, mission, industry, personality, audience, preferred and avoided topics, tone sliders (formal, playful, technical: 1-5), emoji and hashtag style, words to avoid, preferred calls to action and example posts.
list-automations
Everything that creates posts on its own in the workspace: recycling rules (evergreen recurring posts, with next run, runs done and the source post or tag) and RSS feed auto-posts (url, mode, accounts, last poll and last error).
get-repurpose-run
Status of a repurpose-content run that was still going when the tool answered.
list-agents
The background agents switched on for the workspace (for example the pre-publish checker), with type, schedule, settings, whether they are enabled and when they last ran.
list-agent-proposals
Proposals made by the workspace's background agents, newest first; pending ones by default.
list-inbox-drafts
Reply drafts waiting for a person in the social inbox (comments and messages on Bluesky, Mastodon, LinkedIn Page and Google Business), newest first, 25 per page, with the incoming message they answer.
count-characters
Counts a post text the way each network counts it (X weighs links as 23 and emoji as 2, Bluesky counts graphemes, Mastodon drops mention servers) and returns each network's limit, remaining characters and whether the text is over.
check-post
Checks a post text and its media (count, type, video length) against each network's publishing rules without an account: errors that would stop it from publishing (too long, too many hashtags, media missing where the network needs it, too many files, media type, video length) and warnings (see-more cut-off, link not clickable on Instagram).
create-post
Create a post in a workspace and optionally schedule or publish it to the connected social media accounts.
update-post

create-recycling-rule
Re-publishes evergreen content on an interval.
add-rss-feed
Watches an RSS 2.0 or Atom feed every 30 minutes and turns each item published after the feed was added into a post for the given accounts: a draft by default (`mode: draft`), straight into the posting queue (`mode: queue`), or into the queue awaiting approval (`mode: needs_approval`, nothing publishes until someone approves it).
create-report
Generates a downloadable analytics report for a period: a CSV of posts or accounts, or a branded PDF with the workspace's report branding (agency logo, name, colour).
repurpose-content
Turns an article URL, a YouTube video, a public PDF or pasted text into one draft post with a caption written for each target account, plus an image carousel on the networks that take several images.
approve-agent-proposal
Applies a pending proposal at once: `hold_post` moves the post back to draft, `edit_caption` replaces the caption of that version, `retry_account` publishes that failed account again (with the shortened caption, if any), `reconnect_account` only records it (the user reconnects the account in PostBoost).

signup: https://postboost.co/app/registerMCP (Model Context Protocol) is an open standard that lets AI clients like Claude, ChatGPT and Cursor use tools from other apps. PostBoost runs an MCP server, so your agent can work with your social posts directly.
No. In Claude.ai and ChatGPT you add a URL in the settings and sign in. Claude Code and Cursor take one command or one config file.
No for the connector at postboost.co/mcp: you approve the connection with your PostBoost sign-in. Use an access token only for clients without OAuth sign-in, for scripts and for the advanced server.
New posts are drafts unless your agent schedules them, and your client can ask you before any tool that changes something. Tell your agent to keep everything as drafts and your team can review them in the calendar.
