 # Changelog
 
+## 0.34.0 — 2026-09-02 — Leadbay on ChatGPT gets its own address
+
+- **On ChatGPT, add Leadbay as `https://mcp.leadbay.app/chatgpt/mcp`.** Same
+  Leadbay, same sign-in, same leads, same everything — except the assistant
+  cannot generate a top-up link or open your billing page there, and will not
+  suggest buying credits at all. ChatGPT's rules for apps do not allow an app
+  to sell credits or plans, or to push you toward an upgrade. When you run out
+  of quota it tells you which window is empty and when it refills. Buy credits
+  in your Leadbay account as usual; tell the assistant you did, and it picks
+  straight back up where it stopped.
+- **Nothing changes on Claude.** `https://mcp.leadbay.app/mcp` keeps the
+  30-second top-up and the billing link exactly as before.
+- **If ChatGPT was already set up for you**, our installer now points it at the
+  new address on its own.

+Promptforge emits the tool's normal const plus an entry in
+`NO_COMMERCE_TOOL_DESCRIPTIONS` with the block deleted;
+`buildServer({ includeCommerce: false })` serves the second one. Rules:
+
+- **The marker DELETES; it never substitutes.** Never write a softened
+  "ChatGPT version" of a paragraph. If a sentence cannot be removed without
+  rewording the prose around it, gate the whole paragraph instead.
+- Markers go on their own lines for a block. For an inline span, put the
+  leading space *inside* the markers — `resets{{commerce}} (or top
+  up){{/commerce}}.` — so deleting it leaves `resets.`, not a double space.
+- `packages/mcp/test/unit/commerce-gate.test.ts` asserts the gated strings are
+  character-level subsequences of the default ones, so any rewording fails.
+
 Include them via `{{include:rendering/score-bar}}` etc. Don't duplicate
 content across templates — extract a snippet if you find yourself
 copy-pasting.
