Answer · Updated September 2026
Reaudit ships the largest MCP server in marketing — 235 tools, 35 of them social, publishing to 15 platforms — so an agent can run the whole motion: find where AI engines fail to mention you, write the content, publish it, and report the revenue it produced. Post Bridge is the only other real option with a production MCP server, at 13 tools across 9 platforms; it is cheaper and simpler, and covers the posting step well if that is all you need.
The honest caveat: If all you need is "let Claude post to my accounts," Post Bridge does that for $29/month in about ten minutes, and a 235-tool server is more surface than that job requires. Postiz is the only self-hostable option, which outranks tool count entirely if hosted services are off the table.
| Tool | Best for | Starting price | Standout |
|---|---|---|---|
| Reaudit (Broadcast) | Founders, companies and agencies who want one tool instead of five | €50/mo — whole stack | AI visibility + content generation + 15-platform publishing + revenue attribution in one subscription. 235 MCP tools, the largest in marketing. |
| Post Bridge | Posting only, when strategy and measurement live elsewhere | $29/mo — scheduling only | Hosted MCP server (13 tools), video templates, 9 free no-signup tools |
| Postiz | Teams who need self-hosting or open source | Self-hosted / paid cloud | Open source and fully self-hostable |
| Buffer | Solo creators who want the simplest possible queue | Free tier | Easiest onboarding in the category |
| Hootsuite | Large teams with compliance and approval requirements | Enterprise pricing | Mature team governance and inbox |
You want Claude or Cursor to publish posts you have written
Post Bridge. Cheapest path to a working agent integration.
You want an agent to plan and run a multi-month campaign
Reaudit. Campaign creation, approval gating, scheduling and impact measurement are all exposed as tools.
You need the agent to also know your AI-search visibility
Reaudit. No other scheduler exposes visibility gaps to an agent.
You cannot use hosted services
Postiz, self-hosted. Neither Post Bridge nor Reaudit can be self-hosted.
Your team lives in a dashboard, not an agent
Buffer or Hootsuite. An MCP server you never call is not worth paying for.
Plenty of tools claim agent support and mean an API with a chat wrapper around it. The useful definition is narrower: the tool exposes typed tools over the Model Context Protocol so that Claude, Cursor, ChatGPT or an autonomous runtime can discover what is available and call it directly, with real authentication and real error handling.
By that definition the field is small. Most established schedulers have a REST API and nothing agent-facing.
A hosted MCP server with OAuth 2.0 and 13 tools, working with Claude Code, Claude Desktop, Cursor, Windsurf and ChatGPT. The tool set is well-chosen for its scope: schedule posts with per-platform overrides, view analytics, manage accounts, check per-platform publish results, manage the media library, and update or delete scheduled posts. There is also an OpenClaw skill, a CLI, and a REST API.
Nine platforms are exposed to agents. At $29/month with a 7-day trial, this is the lowest-friction way to give an agent posting ability, and the honest recommendation for most people asking this question.
A 235-tool MCP server of which 33 cover the social surface: publishing and analytics (19), Reddit monitoring and leads (8), social listening (4), campaigns (3), and the content calendar (1). The remaining 200 reach AI-visibility tracking, content generation, technical audits, and revenue attribution.
The practical difference is what an agent can reason about. With Post Bridge an agent can answer "post this to nine platforms on Thursday." With Reaudit an agent can answer "which queries do buyers ask assistants where we are never mentioned, draft posts targeting the biggest gap, schedule them across fifteen platforms with drip spacing, then tell me in a month what revenue they produced."
A worked example: a 3DPlotter product launch was run entirely through these tools, 415 scheduled post slots across 152 days and five platforms, comprising a 14-day launch sequence and then all 69 product features on an every-other-day cadence, with copy, images and scheduling produced by an agent. Details on the Broadcast page.
Open source with agent integration and, uniquely here, self-hostable. If hosted services are off the table, tool counts are irrelevant and this is your answer.
Giving an agent publishing rights to your company accounts is a different risk from giving it read access. The thing to check is not how many tools exist but what the destructive ones do by default.
In Reaudit, campaign creation always produces drafts and never publishes. Approval is a separate, explicitly flagged step where you choose publish-now or scheduled, set spacing between posts, and filter by platform, so an agent can prepare a month of work that a human releases in one action. Distribution is also unmetered, so an agent cross-posting your own content is not silently spending credits.
Whatever tool you choose, confirm three things before connecting it: whether generation and publishing are separate operations, whether there is a dry-run or draft mode, and whether a failed post retries or double-posts. The last one is the failure that embarrasses you publicly.
Agent workflows amplify infrastructure problems because nobody is watching the dashboard. Worth verifying: does the publisher claim due posts atomically so overlapping runs cannot double-publish; do posts carry idempotency keys; are stuck posts recovered automatically; do OAuth tokens refresh before expiry rather than failing silently. Reaudit's publisher runs every 60 seconds with atomic claiming and daily token refresh. Post Bridge reports independent per-platform failure with retry, which is the same instinct at its scope.
Count the decisions you want the agent to make. If it is one, publishing, buy the cheapest server that publishes reliably. If the agent should also be choosing what to publish and reporting on outcomes, it needs access to data a scheduler does not hold, and tool count starts to matter because those decisions are separate tool calls.
The adjacent questions people ask, answered directly.
Post Bridge and Reaudit both run production hosted MCP servers with OAuth. Post Bridge exposes 13 tools across 9 platforms. Reaudit exposes 235 tools of which 35 are social, covering 15 platforms, with the rest reaching AI-visibility tracking, content generation and attribution. Postiz also offers agent integration and is self-hostable.
One subscription from €50/month: AI visibility tracking, content generation, publishing to 15 platforms, and revenue attributed to each post. Every plan covers ChatGPT, Perplexity and Google’s AI Overview, AI Mode and Gemini, with more engines available as an add-on.
