Indie Founder Revenue MCP

charlie-morrison/indie-founder-mcp MCP server

A Model Context Protocol server that aggregates revenue across Lemon Squeezy + Gumroad + Polar + Stripe into a single Claude-queryable view. A solo founder can ask Claude "what's my MRR across all my stores?" — and Claude answers from one tool call instead of four browser tabs.

Status: v0.2 — all four adapters shipped. LS + Gumroad live-validated against production; Polar + Stripe offline-validated (live test requires your own org/account). Freemium: 3 tools free, 3 paid (see Pricing).

Tools exposed to Claude

ToolTierWhat it does
summary_mrr(days=30)FreeCombined MRR / ARR across every connected store. Per-provider breakdown.
recent_orders(limit=20)FreeLast N orders across all stores, normalized to one schema.
health()FreePer-adapter healthcheck — useful before the others.
top_customers(limit=10, days=30)PaidHighest-revenue customers in window, ranked by gross USD.
refund_signal(days=7, alert_multiplier=2.0)PaidCurrent N-day refund ratio vs prior N-day window. Fires alert when ratio jumps ≥2x. Zero-case safe.
export_csv_for_tax(year, quarter)PaidCSV export for Ukrainian FOP 3rd-group quarterly filing. NBU USD/UAH exchange rate per-order from bank.gov.ua.

Install (Claude Desktop / Claude Code / Cursor)

Until the PyPI release lands, install from this Git repo via uvx:

{
  "mcpServers": {
    "indie-founder": {
      "command": "uvx",
      "args": [
        "--from",
        "git+https://github.com/charlie-morrison/indie-founder-mcp@main",
        "indie-founder-mcp"
      ],
      "env": {
        "LS_API_TOKEN": "your_lemon_squeezy_token_here",
        "LS_STORE_ID": "optional_store_id_filter",
        "GUMROAD_ACCESS_TOKEN": "optional_gumroad_token",
        "POLAR_API_TOKEN": "optional_polar_token",
        "STRIPE_API_KEY": "optional_stripe_secret_key",
        "INDIE_FOUNDER_MCP_LICENSE_KEY": "optional_license_key_for_paid_tier"
      }
    }
  }
}

Drop this into ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows), then restart Claude Desktop.

What makes this different from the 3 existing LS MCPs

Three open-source LS-only MCPs already exist on GitHub. All expose raw CRUD API calls. None monetized, none aggregated.

This MCP differs:

  1. Multi-source aggregation — one query surface across LS + Gumroad + Polar + Stripe (all four shipped in v0.2).
  2. Summarized indie-founder daily view — MRR, top customer, refund signal, churn risk — not raw API parroting.
  3. CSV export for Ukrainian FOP tax filing — third-section single-tax filers need a specific NBU-rate-anchored format.
  4. Freemium with paid tier — Lemon Squeezy license keys gate the analytics + tax-export tools; the daily-check tools stay free forever.

Production validation

Built and validated on the author's own charliemorrison.lemonsqueezy.com store (store ID 344362) and live Gumroad account:

  • health{"lemonsqueezy": true, "gumroad": true} against each provider's /users/me-equivalent.
  • recent_orders → returns the real $17 Social Media AI Mastery LS order from johannaakoenig@gmail.com on 2026-05-07, normalized into the same schema as Gumroad orders.
  • summary_mrr$0 MRR (correct — no subscriptions converted yet on these stores; the tool's plumbing across active/trialing/past_due statuses is exercised).
  • top_customers(limit=5, days=90) → ranks customers by lifetime USD across all wired providers.
  • refund_signal(days=7) → zero-case alert=False for healthy young stores.
  • export_csv_for_tax(2026, 2) → one row, 2026-05-07,lemonsqueezy,8274123,johannaakoenig@gmail.com,Social Media AI Mastery,17.00,0.00,17.00,43.8528,745.50,745.50 — NBU rate fetched live from bank.gov.ua.

Polar + Stripe adapters are offline-validated (24 fixture tests across all four adapters pass). Live validation against those two requires the user's own Polar org / Stripe account — the adapter wires automatically when the corresponding env var is set.

Pricing

TierPriceTools
Free$0summary_mrr, recent_orders, health — the daily-check loop. Unlimited stores.
Paid$19/mo or $190/yr (2 months free)All Free tools plus top_customers, refund_signal, export_csv_for_tax (analytics + Ukrainian FOP CSV export).

Buy a license: https://charliemorrison.lemonsqueezy.com → drop the key into INDIE_FOUNDER_MCP_LICENSE_KEY and restart your MCP host.

Free tools never check the license — there's no rug-pull. The paid tier is just the analytics + export surface for people who want them.

License & monetization stack

  • Code: MIT (open server; paid features gated by a Lemon Squeezy license key at runtime).
  • License keys: Lemon Squeezy License API (/v1/licenses/validate), 6-hour validation cache.
  • Payouts: LS → Wise USD (proven — $17 cleared on the dogfood store).

Build plan

See PLAN.md for the staged build sequence. v0.2 ships all four adapters + license gate + 6 tools (3 free, 3 paid).

Why this exists

I was opening four dashboard tabs (Lemon Squeezy, Gumroad, Polar, Stripe) every morning to check MRR and recent orders, then re-doing the same math in a spreadsheet for FOP tax filing. So I asked Claude to consolidate it. This is the result — and now Claude does the morning check itself.
