Post Bridge and Flaghand both have an API and a hosted MCP server. Choose Post Bridge for broader cross-posting and an agent that can schedule or publish directly. Choose Flaghand for reviewed X and personal LinkedIn posts when an agent credential must never be enough to approve, schedule or publish.
Checked on October 31, 2026. Prices, account support and publishing behavior below are dated to this check; the sources link each product's official pages.
The short answer
- Post Bridge is already agent-capable. Its MCP
create_postcan publish, schedule withscheduled_at, use the next queue slot withuse_queue, or save a draft withis_draft. API and MCP access are included on current plans. - Flaghand separates preparation from permission. An agent drafts, checks and requests approval. The owner approves the exact account, content and time in Flaghand with a passkey; the server then creates the publishing job.
- Compare accounts and destinations before comparing prices. Post Bridge publishes to ten networks and sells explicit 15-account and 99-account starting bundles. Flaghand's current publishing fit is X and LinkedIn personal profiles, not an equivalent ten-network bundle. TikTok drafts are beta; general TikTok publishing is subject to TikTok's review.
Where Post Bridge is a better fit
Post Bridge lists X, Instagram, LinkedIn, Facebook, TikTok, YouTube, Bluesky, Threads, Pinterest and Google Business. Its LinkedIn help supports personal accounts you own and Pages that the connected personal account owns, with the correct permissions. Flaghand does not publish as LinkedIn company Pages.
Its plans explicitly allow multiple accounts on the same platform: 15 connections can all belong to one network. Operator adds team invitations. Its account help says team seats are for people posting to one business's accounts; people running their own independent brands need their own Post Bridge accounts. A team seat and a connected social account are different units.
Choose that broader coverage when you need an agent to distribute media across those networks, batch-schedule videos, use a publishing queue or read the advertised analytics (beta). Flaghand is not a replacement for all of those destinations or analytics features.
Pricing and access
Post Bridge's current public plans are in US dollars:
| Plan | Billed monthly | Billed yearly | Connected social accounts |
|---|---|---|---|
| Marketer | $39 a month | $390 a year, equivalent to $32.50 a month | 15 total, including multiple on the same network |
| Operator | $99 a month minimum | $990 a year minimum, equivalent to $82.50 a month | 99 minimum; $1 per additional account a month, or $10 per additional account a year |
Yearly means an annual bill, not a monthly subscription at the equivalent rate. For example, 100 Operator accounts cost $100 billed monthly or $1,000 billed yearly. The yearly selector advertises two months free. Both plans advertise a seven-day trial with $0 due today. Current plans include REST API, CLI and MCP access; the API billing article distinguishes older subscriptions that may still have an API add-on.
Check X link-post costs separately. Although Post Bridge advertises unlimited posts on paid plans, its MCP reference says links are stripped from the main X post unless the “Links in X posts” add-on is enabled: $10 a month for 40. It suggests putting links in first_comment otherwise. A link in a reply is not the same outgoing post as a link in the main text.
Flaghand starts with seven days of free drafting without a card. Add a card for the first approval, or by day 7 to keep drafting; otherwise reading and export remain available. See current plans and full first-charge terms, including any founding offer and its renewal, before choosing. A card or a payment never approves a post.
On the checked date, Flaghand's public pricing includes 300 X posts a month, 30 with a link, and 1,500 monthly credits. Optional X-reading automations spend credits; drafting, approval and posting do not. Neither product's base price alone is a promise of unrestricted platform usage.
What MCP approval means
Post Bridge recommends drafting first, reviewing in its dashboard, then scheduling. Its is_draft option saves inside Post Bridge, not as a draft on every social network. Its documentation also exposes a publishing-capable create_post flow. That is an optional draft-and-review workflow, not a documented requirement for a separate owner passkey over each post. This does not establish that Post Bridge lacks every review feature or permission setting.
Connecting an MCP client through OAuth, authorizing a social account and confirming a tool call in a chat app are not the same as approving the exact publishing snapshot. Post Bridge supports OAuth for its hosted MCP connection and API-key authentication for integrations; revoking either stops that connection.
In Flaghand, no API token can approve, schedule or post. The owner approves a frozen snapshot with a passkey, and the scheduler checks the matching approval again before publishing. Changing the approved content, destination account or time requires a fresh approval. One plan can contain several posts; one X thread is not a separate approval tap per part.
The agent's documented workflow is:
- Use
listConnectionsto choose the intended activeconnection_id, then upload media and prepare the proposed posts and times. - Call
createPostto draft, check and request approval in one call, or usecreateDraft,checkDraftandrequestApprovalseparately. A proposedpost_atdoes not schedule a publishing job. - Return the product's approval request. The owner reviews and approves inside Flaghand; the agent cannot take that step for them.
- Read job results after the approved time. For X,
verifyJobcompares the available live content with the approval. It does not verify link destinations or media-file identity; LinkedIn read-back is unavailable.
Accounts and calendars: what is available now
Flaghand's live API identifies destination accounts by connection_id; its agent guide requires an explicit destination when multiple connections are present. Its public plans do not state a numerical social-account allowance. Do not assume a 15-account or 99-account entitlement, or infer a one-account limit from a two-network description. The owner completes each platform's consent; an agent can prepare the connection link, not grant that consent.
The current desk documentation describes Queue's seven-day view of scheduled, posted and held posts. Weekly posting slots propose times for new drafts, and the private calendar subscription exposes approved jobs to a calendar app. The subscription is read-only; it cannot approve, schedule or post.
Further calendar work is planned. This comparison counts the documented week view, proposed times and calendar feed as available now, not a promised calendar editing or rescheduling workflow. Calendar plans do not give an agent permission to move an already approved publishing job without another owner approval.

Decide by the permission you need
If your integration should publish unattended across many destinations, Post Bridge's documented publishing tools and account bundles are the closer fit. If an agent should prepare a week's posts but never possess the authority to release them, Flaghand's required owner approval is the reason to choose it.
