Quo plugs into Claude as a callable business-comms tool while transcripts become first-class data.
Quo's recent shipping is two-pronged. The headline move is an official Claude connector that turns the product into an action surface for AI — summarizing calls, sending texts, looking up and editing contacts. Around it, the team is treating call transcripts as searchable, exportable data and tightening the HubSpot integration so contact edits flow both ways.
Slack is turning its app platform into an AI-agent surface — MCP on both ends, richer Block Kit.
The developer-facing changelog is busy and coherent: a Slackbot MCP client and expanded Slack MCP server tools, new Block Kit blocks (data visualization, data table, alert/card/carousel), streaming API updates for AI assistants, and a steady drumbeat of CLI and SDK releases.

Quo is positioning itself as the business-phone surface that AI assistants reach into. The Claude connector gives Quo distribution inside an AI client; transcript search and markdown exports make Quo conversations queryable by humans and agents alike; the HubSpot two-way edit removes the last 'open another tab' moment in a sales call. The trajectory points to AI-native customer-conversation workflows, not just calling and texting.
Expect more agent connectors (ChatGPT, custom MCP) and more agent-callable verbs (initiate calls, draft follow-ups, push transcripts into pipelines). Watch for deeper CRM-write integrations beyond HubSpot — Pipedrive, Salesforce — to keep parity as the agent surface grows.

Slack is positioning itself as both an MCP host (Slackbot calling external tools) and an MCP server (external agents acting in Slack), while Block Kit gains data-rich primitives and the streaming API matures for assistant experiences. The direction is making Slack a first-class surface for AI agents and data apps.
Expect deeper MCP capabilities and more data/visualization blocks, with continued frequent CLI/SDK releases supporting the agent-and-app platform push.
