Integration

ReachInbox integration

ReachInbox runs cold email outreach from many connected mailboxes. Create and run campaigns (sequences, schedules, sending accounts, options), add, update, pause and delete leads, manage lead lists, read campaign and warmup analytics, work the Onebox unified inbox (list, read threads, send replies), manage email accounts (warmup, settings, DNS checks), blocklists and tags. Not exposed: connecting mailboxes (OAuth link, IMAP/SMTP passwords), inbox placement tests, and the bulk ALL forms of account and lead-list routes. Authentication is the workspace API key (Settings, Integrations, API) sent as a Bearer token; rate limit 5 requests per second.

Ask it in chat

Say what should happen.
The workflow builds itself.

When this happens, do that in ReachInbox.Built from the 60 ReachInbox tools below, on the connection you add once.

What you can do with ReachInbox

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.

Use ReachInbox from Claude Code, Cursor or Codex

Connect ReachInbox in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its ReachInbox 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"
      }
    }
  }
}
