Changelog¶

Notable changes to The Coin Daily MCP and this guide. Historical entries below describe their release at the time, not the current tool catalogue.

Added the combined Market regime and volatility widget: observed hourly variation on 4-hour, 1-day and 7-day horizons, historical percentiles and frozen state colours, with one shared selected-hour reader. The MCP now exposes 28 tools across 14 widget families.
The account experience now uses Coin Daily email/password or Google sign-in, with explicit Link Google from an existing signed-in account. Membership recovery stays a separate, mailbox-proved action; matching emails are not treated as linked accounts.
The shared evidence store is restart-safe: a routine service replacement no longer discards an unexpired capture. Captured evidence still normally expires within about 15 minutes; ask for a new read instead of expecting a permanent archive.
Added the customer sign-in and account guide and the market regime and volatility guide, and corrected study defaults, counts and update guidance across the guide.

2026-09-15 — A guide for both research experiences¶

Added Research Desk walkthroughs for chart selection, full-range explanations, cohort controls, asset discovery and the Desk Brief.
Added a plain-English glossary focused on what each reading contributes.
Reorganised navigation into Research Desk, AI-assistant workflows, reading guides and account help. Technical contracts remain available separately at their existing URLs.
Updated the product page around practical research questions, with links to these walkthroughs. Pricing and product access are unchanged.

Replaced the publication-oriented MCP with 13 focused widgets and 26 tools using the same Research API as the browser product.
Added price replay, native metric/study views, pinned cohort comparisons and dated news/video context. The Market Update retains its published chapter evidence.
Research and MCP use the same current subscription check. Old token/key tier labels do not establish entitlement; temporary billing failures remain retry states.
Updated the product, account, setup and methodology guides. Retired widget screenshots and internal operational documents are no longer part of the public guide.
The established public reference URL now documents only the current Research tools. See the catalogue.

Added configuration-derived market-universe discovery. The MCP recognises the reviewed 246-instrument observed-market catalogue while reporting Analyst and quantitative artifact availability as separate publication layers.
Bare, -USD, and observed-market -USDC ticker forms now resolve to the same public ticker; unsupported quotes fail closed.
Active Analyst publication now covers all 246 configured tickers in one immutable cohort: 246 MIAs, ranks 1–246 and a same-cut 246-population MAR.
The public Signal Book rank is the deterministic analytical-attention order. Retired scalar direction/conviction and LLM tradeability semantics are not reintroduced.
OAuth discovery now uses the public MCP issuer while preserving Cognito token issuer/JWKS validation, and supports PKCE clients through DCR.

The Coin Daily MCP is now a subscription: $19/month or $190/year, with a 7-day free trial for new customers (one trial per customer and per card; renewals bill from day one). Access activates automatically at checkout and self-corrects on your next request if you subscribe after connecting.
The product is used entirely through Claude and ChatGPT — add the connector, sign in, ask.
New product page and a new Manage your subscription guide (renew, cancel, payment failures, lapse behaviour).
This guide was rebuilt around the Widget catalog — screenshots first, plain language throughout — with a refreshed design in light and dark.

Added the Daily Read widget — the flagship synthesized daily briefing (cross-market summary, key tension, tone/confidence, and analytical-attention rows with level context).
Added My Watchlist — the publication's read on your own coins, editable and remembered across sessions.
Every response now carries a not_live_quote_notice alongside the existing disclosure — an explicit flag that values are timestamped publication snapshots, not executable exchange quotes.
Refresh cadence documented correctly as roughly every 30 minutes.
New Methodology section — how the analysis is produced, and the editorial gates every brief and report pass.
New Widget catalog — every card and what to ask for it.
