MCP + REST API for social media

Give AI agents the power to publish, with human approval when you need it.

Postato is the execution layer that lets AI agents create, approve, schedule and publish across social networks with built-in governance and reliability.

// Discover account, publish, verify status
const accounts = await mcp.callTool("list_accounts", { platform: "linkedin" });

const { id } = await mcp.callTool("publish_post", {
  accountId: accounts[0].id,
  content: "New feature shipping today: schedule posts with a single API call. Details in the comments.",
  scheduledAt: "2026-04-08T14:00:00Z"
});

const status = await mcp.callTool("get_post_status", { postId: id });

Postato is agent execution infrastructure for social media. Not a scheduler. Not a dashboard with AI bolted on. It's the API and MCP layer that turns publishing, approval, scheduling and observability into capabilities your agents and AI-native products can call directly.

Why Postato

Five things every agent execution layer needs.

Capability is the foundation. Trust, governance, reliability and builder experience make it work in the real world.

01, foundation

Capability

Real actions for agents, not just text generation. Drafts, validation, scheduling, publishing, status, metrics, asset handling. Every primitive your agent needs to operate social distribution as a first-class capability.

Trust

Agents act through scoped, mediated access. No raw credentials. Revoke anytime.

Governance

Draft-first by design, literal. Approval routes per agent, per network, with team-based review and business-hours windows. Every state change is audited.

Reliability

Idempotency, retries, queues, webhooks, explicit states. CSV audit export, per-agent metrics, and queue health in one dashboard. Execution as a product.

Builder DX

One integration, multiple networks. MCP, REST, SDKs. Predictable JSON, agent-ready primitives.

How it works

From agent prompt to published post, with governance in the loop.

Four steps. Change the policy without changing a line of agent code.

Connect networks once

Authorize your social accounts via the official APIs. Tokens are encrypted and scoped per agent.

Agent calls publish_post

Your AI agent (or any backend) sends a finished post via MCP or REST. Content, media, options: Postato handles validation, idempotency, and retries.

Policy decides the route

Direct publish, require approval, or save as draft, per agent and per network. When approval is required, the post waits for review and a webhook fires.

Human reviews, post ships

A teammate reviews in the dashboard, approves or rejects with reason, and Postato delivers via the official APIs. Every step is in the audit log.

For builders

Built for indie hackers and AI-native startups.

Connect accounts once. Let your agents publish in minutes, not weeks of integration work per network.
