Your agent Example

Everything you can do in the API, you can do with MCP.

MCP server

Streamable HTTP at /mcp on the dashboard host. Tools come from the catalog API. The same KYC, payment, and send gates apply.

Connect MCP

Role-based keys

Full access for setup. Support for the help desk. Support can research delivery. It cannot reconfigure the account.

Create a Support key

Platform API

Every MCP tool is a documented REST endpoint. The token's team is taken from the key.

Read the API reference

Connect in three steps.

1
Mint a key

Open API keys. Choose Full access for setup or Support for the help desk.
2
Paste the config

Add the mcp.json block to your MCP client. Put the token in the Authorization header.
3
Ask a question

Ask whether they got the email, whether Gmail is unhealthy, or to create a shared-IP cluster.

{
  "mcpServers": {
    "postshiba": {
      "url": "https://app.postshiba.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Deploy, operate, and answer.

Deploy

Create a shared-IP cluster, wait until it is sending-ready, then change region, size, or plan.

create_cluster name=production

get_cluster sending_ready=true

update_cluster region size plan

boost_cluster temporary capacity

Operate

Pause one tenant while you investigate. Leave the rest of the platform sending.

suspend_tenant acme

resume_tenant acme

suspend_sending_domain mail.acme.com

create_suppression user@example.com

Answer

Read delivery by mailbox provider, look up one recipient, and follow the events.

get_analytics dimension=mx_provider

lookup_recipient user@gmail.com

list_team_message_events mx_provider=gmail.com

get_status sending is not held

Scoped keys so support can lookup an email but not take down production.

Full access

Every catalog tool. Create clusters, pause tenants, send mail, and rotate credentials. The same gates as the dashboard.

Support

Five tools. whoami, lookup_recipient, get_analytics, get_status, and destroy_suppression. Any other tool returns 403 forbidden.

No SMTP passwords, webhook secrets, DKIM private keys, or raw bounce payloads. Digits in subjects are masked. The token stays in the Authorization header.
