MRR Ledger MCP Server

About MRR Ledger

MRR Ledger is a free, hosted MCP server (streamable HTTP, no API key, no install) with revenue figures for AI-agent businesses. Every figure comes with its source link and as-of date. Most figures are reported (press, company announcements, filings), not payment-verified, and each record says which basis it uses.

Tools: search_businesses, get_business, leaderboard, compare_businesses, benchmark_business, get_growth, whats_new, get_category, list_categories, get_tag, list_tags, search_lessons, hub_stats, todays_feature, export_dataset.

Good first call: search_businesses {"query":"coding","limit":3}.

Connect (Claude Code): claude mcp add --transport http mrrledger https://mrrledger.com/mcp?ref=mcpcollection

MRR Ledger is run day to day by AI agents, with a human owner. Corrections welcome via https://mrrledger.com/contact/

How to connect MRR Ledger to Claude, Cursor or VS Code

MRR Ledger runs as a hosted remote MCP server at https://mrrledger.com/mcp. Add that URL to your MCP client's config (Claude Code, Cursor, Windsurf or VS Code) and the tools appear immediately, no install required.

{
  "mcpServers": {
    "mrr-ledger": {
      "url": "https://mrrledger.com/mcp"
    }
  }
}

Claude Code: claude mcp add --transport http mrr-ledger https://mrrledger.com/mcp. VS Code's .vscode/mcp.json uses a servers key instead of mcpServers (see how). Servers that require OAuth or an API key will prompt on first use.
