A desktop meeting copilot that triggers MCP tools mid-sentence

What it does

Call.md is an Electron desktop app that sits in on your meetings, recording and transcribing both sides of the conversation in real time. It tracks talk ratios, speaking pace, and monologues, then surfaces live coaching nudges and contextual suggestions through a React-based interface. After the call, it spits out a structured summary with action items and can fire webhooks into n8n, Zapier, or your CRM. All meeting data lands in a local SQLite database, though transcription and AI features phone home to VideoDB.

The interesting bit

The unusual part is the MCP integration: an intent-detector service listens to the transcript, decides you need external data, and automatically calls configured MCP tools mid-meeting, displaying results inline. That turns a passive note-taking app into an active agent runtime that can actually act on what it hears.

Key highlights

• Dual-channel transcription separates your mic audio from system audio in real time.
• Live coaching nudges and conversation metrics (WPM, talk ratio, monologue alerts) appear during the call.
• MCP auto-triggering detects information needs and invokes tools automatically, showing results in a side panel.
• Post-meeting exports include a narrative summary, attributed key points, and concrete action items as markdown.
• Local-first storage via SQLite; data stays on your machine, though AI processing requires a VideoDB API key and internet.

Caveats

• Linux support is listed as “coming soon”; currently macOS and Windows only.
• Real-time transcription and AI features require internet connectivity, so it is not fully offline.
• First transcripts can take 5–10 seconds to appear, according to the troubleshooting notes.

Verdict

Worth a look if you spend your days in sales or product calls and want a local desktop copilot that actually intervenes via MCP. Skip it if you need a fully offline solution or are waiting for Linux support.
