# Chorus documentation

Research date: 2026-09-02

Documentation coverage: partial.

Reference index, not a mirror of complete vendor documentation. Retrieved pages do not prove the MCP works.

## What it does

Records, transcribes, and analyzes sales calls, meetings, and emails, and syncs the resulting insights into the CRM.

## Access and connection

MCP support: community

Access requirements: enterprise-only (inferred, not an explicit vendor statement). No public self-serve pricing exists - the product page routes only to "Request Demo," and secondary sources note API access is not included on every ZoomInfo/Chorus plan.

Authentication: Community server: Chorus API key in the CHORUS_API_KEY environment variable (stdio via npx @opensourceops/chorus-mcp), with CHORUS_TOOL_MODE defaulting to readonly. The REST API uses a per-user API token generated in Chorus's Personal Settings page.

Research checked: 2026-09-02

These details come from catalog research. Check vendor sources for current setup instructions; this is not proof of a tested connection.
