Integration

Mailbox Power integration

Mailbox Power sends physical greeting cards, postcards and gifts by mail, one-off or through automations (birthday, drip and other campaigns). An agent can list contacts, create contacts (optionally in a group), list and create contact groups, add a contact to or remove it from a group, list automations, and add a contact to an automation, which starts real mailings billed to the account (postage at USPS rates plus the products sent). Contact mailing addresses, birthdays, family names, notes and custom merge fields are not returned by the reads, and the address-collection link of each group is not returned. Deleting contacts or groups, renaming groups, updating contacts and listing a group's contacts are not exposed. Authentication is the API key from your Mailbox Power account (Integrations & API menu), sent in the APIKEY header.

Say what should happen.
The workflow builds itself.

When this happens, do that in Mailbox Power.Built from the 8 Mailbox Power tools below, on the connection you add once.

What you can do with Mailbox Power

Each of these is one operation on one endpoint, available both as a workflow step and as a tool an AI agent can call on its own. Nothing bundles several operations into one action, so what a run did stays readable afterwards.

Most endpoints run on the free plan. A few, mainly the ones that publish on your behalf, need a paid plan.

Contact, 2 operations

create_contactCreate contactPOSTCreates a contact (pass forcenew=true), or with forcenew=false updates the existing contact whose name, street, city and state match. Optionally adds it to a group (groupId). Returns ID.
list_contactsList contactsGETLists all the account's contacts: id, names, company, email, phones, group IDs and names, dates. Mailing addresses, birthdays and other personal details are not returned. Use id with the group and automation tools.

Contact group, 2 operations

create_contact_groupCreate contact groupPOSTCreates a contact group with a name (groupname) and returns its ID (GROUPID).
list_contact_groupsList contact groupsGETLists the account's contact groups: ID, name, number of contacts and message. Pass ID as groupId to create_contact, add_contact_to_group or remove_contact_from_group.

Group contact, 2 operations

add_contact_to_groupAdd contact to groupPOSTAdds an existing contact to a contact group. Pass contactId from list_contacts or create_contact and groupId from list_contact_groups.
remove_contact_from_groupRemove contact from groupDELETERemoves a contact from a contact group (the contact itself is kept). Pass contactId and groupId.

Automation, 1 operation

list_automationsList automationsGETLists the account's automations (mailing campaigns): AUTOMATIONID, AUTOMATIONNAME, TYPE (for example BIRTHDAY or DRIP) and STATUS (for example ACTIVE or PAUSED).

Automation contact, 1 operation

add_contact_to_automationAdd contact to automationPOSTAdds a contact to an automation for real: the automation then mails that contact its cards or gifts, billed to the account (products plus postage). Pass automationId from list_automations and contactid.

Use Mailbox Power from Claude Code, Cursor or Codex

Connect Mailbox Power in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its Mailbox Power operations become tools the client can call, next to every other integration you connected.

Claude Code

claude mcp add --transport http livecontext https://livecontext.ai/mcp --header "X-API-Key: YOUR_API_KEY"

Codex (~/.codex/config.toml)

[mcp_servers.livecontext]
url = "https://livecontext.ai/mcp"

[mcp_servers.livecontext.http_headers]
"X-API-Key" = "YOUR_API_KEY"

Cursor, Claude Desktop and other JSON configs

{
  "mcpServers": {
    "livecontext": {
      "type": "http",
      "url": "https://livecontext.ai/mcp",
      "headers": {
        "X-API-Key": "YOUR_API_KEY"
      }
    }
  }
}

Set up the MCP server step by step

The workflow builds itself in front of you and picks the endpoints it needs. Drag the steps yourself on the canvas whenever you would rather be explicit.
