Shager for Agents

Your agent already writes. Now it ships.

Shager is distribution infrastructure that agents work with directly: an MCP server, a documented API, and a sign-up an agent can do on its own. The agent creates, schedules and measures, and a person approves before anything goes live.

01Quickstart

Three steps, no SDK.

The agent opens a sandbox

One call returns an API key and a claim link. In the sandbox the agent can create clients, upload media, build drafts and previews, but not publish.

POST /api/v1/agent/signup

curl -X POST https://app.shager.ai/api/v1/agent/signup \
  -H 'content-type: application/json' \
  -d '{"agent_name":"Acme marketing agent",
       "contact_email":"owner@acme.com",
       "purpose":"Distribute weekly videos to 40 branch pages"}'

200 OK

{ "data": {
  "api_key": "shgr_live_…",
  "claim_url": "https://app.shager.ai/claim/…",
  "sandbox": true,
  "mcp_url": "https://app.shager.ai/api/mcp",
  "expires_at": "…"
} }

Connect the MCP server

Paste the config into Claude Desktop, Claude Code, Cursor or any MCP client. Or work directly against the REST API.

mcp.json

{
  "mcpServers": {
    "shager": {
      "url": "https://app.shager.ai/api/mcp",
      "headers": { "Authorization": "Bearer shgr_live_…" }
    }
  }
}

03
A person claims it, the agent ships
The owner opens the claim link, signs in and connects the accounts (or sends the client a connect link). From then on, the agent schedules and publishes for real.

03Safety

The agent executes. A person decides.

Nothing goes live without a person: A sandbox an agent opened stays in draft until a person claims it with the link.
Scoped keys: Every key belongs to one organization and can be revoked at any time.
Rate and volume limits: Per-account and daily publishing caps, and staggered delivery that respects network limits.
Audit log: Every agent action is recorded: who, what, when and with which key.

Live networks: Facebook (Pages), Instagram (professional accounts), YouTube. TikTok and LinkedIn are in development.
Publishing only through official APIs, and only to accounts the user manages and is authorized to post to.
Numbers on this site are illustrations unless stated otherwise.

What we're building next

OAuth sign-in for MCP: Sign in with your Shager account straight from the MCP client, with no key to copy.
CLI: A command line with device login, for scripts and CI pipelines.
A billing link for your human: The agent sends a person a checkout link, then works within a budget the person sets.

API and MCP are included on every plan. See pricing
