Missive integration

Missive public API v1, the shared inbox that puts email, SMS, WhatsApp and social channels in one collaborative thread. List and filter conversations by inbox, assignment, state or shared label, open one and read its messages, its internal comments and its integration posts, assign it, label it, close or reopen it and merge duplicates, create email drafts and send them, publish integration posts into a conversation, and manage the contact database with its contact books and groups. Also exposes the organisation directories of teams, users and shared labels.

What you can do with Missive

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 Missive from Claude Code, Cursor or Codex

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