Typed diffs between observations
  1. Plain Freight Official MCP Registry estimate_price: description changed (+"10" -"100")
  2. Piloxa Official MCP Registry authorize_certified_letter: tool added
  3. Piloxa Official MCP Registry server instructions changed (+"Where your platform can give you a Stripe shared payment token for the exact total, the person can also approve and pay without leaving the conversation: state the exact total, recipient and service, get their explicit yes for that total, then call authorize_certified_letter with the mailing_id from prepare_certified_letter and one idempotency key you reuse on every retry. Its transaction_state says exactly where the letter stands; never say a letter was sent before it reads VENDOR_ACCEPTED or later.")

  5. io.github.lonniev/personalbrain-mcp Official MCP Registry brain_update_coupon: description changed (+"``tool_ids`` replaces the coupon's binding — tool ids or MCP tool names, ``["*"]`` for every paid tool, ``[]`` to unbind it.")

  7. io.github.lonniev/personalbrain-mcp Official MCP Registry brain_mint_coupon: description changed (+"The coupon owns its binding: ``tool_ids`` names the tools it discounts, and re-pricing a tool never touches it. A coupon bound to no tool discounts nothing, however many patrons redeem it.")

  9. PeopleSearch.im Official MCP Registry people_search: input schema changed
  10. PeopleSearch.im Official MCP Registry people_search: description changed (+"To look up one named person, give `first_name` and `last_name` with their company or company domain when known. For a kind of employer no industry names exactly, use `company_keywords` (words its own description contains, for example ["hostel"] or ["SEO"] with industries ["Marketing Services"])." +"search broadens itself: a job title is read more broadly first (`broadenedRole` gives the title as asked and as searched), then the" -"automatically")
  11. PeopleSearch.im Official MCP Registry find_people: input schema changed
  12. PegaRex Official MCP Registry get_fipe_valuation: description changed (+"`fipe_year` é o ano FIPE usado; 32000 é como a FIPE escreve "0 km" (carro novo) — mostre `fipe_year_label` ("0 km"), nunca "32000".")
