v0.5.02026-06-13

Added

  • Fenek Pro is live. Crypto sources (Bybit, on-chain wallets) now require a Fenek Pro license key, validated about once a month against Polar (the merchant of record, api.polar.sh); the check sends only the license key. Classic brokers (Trading 212) and the cross-broker analytics stay free, and the official free self-build path npm run pack:freepro (docs/building-pro.md) still unlocks everything without a license. Built on the tier-aware tool registry and license manager (monthly verdict cache, 14-day grace, "revoked" distinguished from "unreachable") with the LICENSE_KEY field stored in the OS keychain.
  • Update notices. Fenek now reminds you in chat when a newer version is out: a no-network age-based nudge when a build is over two months old, plus an opt-out weekly check against api.github.com that reads only the latest release number. Toggle it with the new "Check for updates weekly" setting (CHECK_UPDATES). The manifest's homepage and privacy links now point at fenek.tech.
v0.4.12026-06-12

Security hardening release: closes every finding from a full audit of the codebase, CI pipeline, and MCP surface. No new tools, no new data.

Security

  • On-chain token symbols (TON jettons, Solana SPL tokens via Jupiter) are sanitized before they reach tool results: control, bidi-override, and zero-width characters are stripped, whitespace is collapsed, and length is capped at 32. Anyone can mint a token with an arbitrary name and airdrop it to a watched wallet, which made this the one provider field a third party could weaponize for prompt injection. The server instructions now also direct the model to treat instrument and token names as data, never as instructions.
  • Schema-mismatch diagnostic dumps are redacted (credential-shaped fields removed) and size-capped before reaching stderr, which Claude Desktop persists to a local log file. Bybit's key-info endpoint echoes the API key in its response, so schema drift there would previously have written the key to that log.
  • Authenticated broker requests refuse HTTP redirects (redirect: "error"): fetch does not strip Bybit's custom X-BAPI-* auth headers on cross-origin redirects, and no broker read endpoint redirects legitimately.
  • The release workflow is split into a read-only test job and a minimal write job, so the dev toolchain never executes next to tokens that can rewrite releases or mint attestations. Dependency lifecycle scripts are disabled in CI (--ignore-scripts), actions are pinned to commit SHAs, checkout credentials are not persisted, and the .mcpb is packed with the lockfile-verified mcpb CLI instead of an unverified registry re-fetch.
  • GitHub vulnerability intake is enabled: Dependabot alerts and private vulnerability reporting (the channel SECURITY.md documents).

Fixed

  • Every outbound request now carries a 15-second timeout, so a hung provider cannot wedge a tool call (crypto wallets are read sequentially, which multiplied any hang).
  • A provider-supplied Retry-After header is honored up to 60 seconds instead of verbatim (a malicious 86400 would have put the call to sleep for a day).
  • Jupiter limit-order pagination is capped at 20 pages instead of trusting the provider-reported page count unbounded.
  • Free-form tool inputs (pagination cursor, search query, pie id, coin ids) are length-capped at the schema boundary.
  • In-memory TTL caches are bounded (1000 entries, FIFO eviction); they previously grew without limit because entries expired only when re-read.

Changed

  • Every tool now declares openWorldHint: true for network-backed broker and analytics tools, false for local-only playbooks and onboarding.
  • PRIVACY.md names every outbound host (adds litecoinspace.org and Jupiter) and documents the local-log behavior on schema drift; README gains a "Verify your download" section with the gh attestation verify command.
  • Checksummed synthetic addresses replace live-chain vectors in tests.
v0.4.02026-06-11

Full exchange data coverage: every read-only money bucket Bybit and Trading 212 expose is now reachable, and previously stripped response fields are kept.

Added

  • Bybit derivatives — bybit_get_derivative_positions: open USDT/USDC perpetual, futures, inverse, and options positions with side, size, entry/mark price, unrealized and realized P&L, leverage, liquidation price, and TP/SL. Previously invisible.
  • Bybit Earn — bybit_get_earn_positions: staked and saving balances across flexible savings, on-chain staking, fixed-term deposits, the BYUSDT yield token, and dual-asset products, with APY (normalized to percent) and claimable yield. Earn funds never appear in wallet balances, so they were invisible. Requires the Earn read permission.
  • Bybit all-account overview — bybit_get_balances_overview: total equity in USD across every account type (Funding wallet, Unified Trading, Earn, Trading Bots, Copy Trading, Launchpool) with per-account coin holdings, plus Funding-wallet quantities. Requires the Assets/Wallet read permission.
  • Bybit account & margin health — bybit_get_account: total equity, wallet/margin/ available balances, perp UPL, margin rates (IM/MM — liquidation-risk indicators), and per-coin equity, unrealized/realized P&L, borrow amount, accrued interest, locked.
  • Bybit key diagnostics — bybit_get_key_info: read-only flag, permission groups, IP allowlist, expiry (warns within 14 days), margin mode, and UTA status.
  • Trading 212 exchange hours — t212_get_exchanges: venue working schedules including pre-market, after-hours, and overnight sessions; joins instruments via workingScheduleId.
  • Trading 212 richer history — executed orders now include limit/stop price, quantities, time-in-force, and realized P&L per fill; dividends include the instrument name, quantity, gross amount per share, and the event kind (ordinary/bonus/interest/...).
  • Trading 212 honest pies — pie lists now actually return dividend totals (gained/reinvested/in-cash), goal progress, and status; pie details report the dividend cash action (reinvest vs to cash).

Changed

  • Trading 212 account data is read from /equity/account/summary alone (one HTTP call instead of two) and now includes all-time realized P&L; the legacy /equity/account/cash endpoint remains as a fallback for older API revisions.
  • Bybit getAccount reports the exchange's totalEquity (includes derivatives UPL and option value) instead of summing spot coins, and carries perp unrealized P&L.
  • The Bybit key-setup guidance now lists the exact read permission groups (Unified Trading, Assets/Wallet, Earn); tools missing a group fail with an error naming it.
v0.3.02026-06-06

Added

  • Crypto wallets now cover Bitcoin, Litecoin, and Dogecoin alongside Solana and TON — all read keyless, with no API keys, via public endpoints.
  • A single Wallet addresses field replaces the separate per-chain fields: paste any mix of addresses (commas, spaces, or new lines) and each address's chain is detected automatically from its format and checksum.
  • crypto_get_positions reports addresses it skipped — unrecognized, on a not-yet-supported chain, or failed to load — instead of dropping them silently.

Changed

  • Solana is now keyless. Holdings are read from a public Solana RPC node (native SOL plus SPL Token and Token-2022 accounts); the Helius API key is no longer used.

Removed

  • The SOLANA_ADDRESS, TON_ADDRESS, and HELIUS_API_KEY configuration fields, replaced by the single keyless Wallet addresses field.
v0.2.22026-06-05

Changed

  • Point the manifest author field at the maintainer's GitHub profile (a directory submission requirement).
v0.2.12026-06-05

Connector configuration simplified.

Changed

  • Trading 212 demo vs live is now detected automatically from the API key; the ENVIRONMENT setting is gone. Every credential field is optional, so you configure only the sources you use.
  • Config fields are grouped by provider with clearer titles and shorter descriptions; the getting-started pointer now lives in the extension overview instead of being crammed into the first field.

Added

  • fenek_getting_started — a credential-free overview of what the extension does and how to set it up, runnable before any keys are entered. Exposed as both a prompt and a tool, so clients that surface only tools (not prompts) can reach it too.

Fixed

  • Cross-broker tools (portfolio_overview, portfolio_concentration, portfolio_pie_overlap, portfolio_dividend_history) no longer fail entirely when a single broker errors (e.g. an expired key → 401). They return the healthy brokers' data and report per-broker failures in an errors field.

Removed

  • The LANGUAGE setting and the Russian prompt translations. Prompts are English; the model replies in the user's language conversationally.
v0.1.12026-06-04

Directory-compliance and metadata release ahead of the Anthropic MCP Directory submission.

Added

  • Human-readable title and a readOnlyHint: true annotation on every MCP tool. The read-only hint is stamped centrally in the tool registry, so no tool can be exposed without it and a binding cannot override it.
  • privacy_policies link in manifest.json and a Privacy Policy section in the README.
  • docs/submission.md with the directory review packet.
v0.1.02026-06-04

First public release, submitted to the Anthropic MCP Directory.

Added

  • Read-only data aggregation across EU-available sources: Trading 212 (positions, pies, dividends, transactions, order history), Bybit (coin balances, open orders), Solana/TON wallets, and Jupiter limit orders.
  • Cross-source analytics: overview, concentration, pie overlap, dividend history.
  • Slash-prompt playbooks (overview, concentration, pie, dividends), EN + RU.
  • CI (typecheck/lint/test/audit), DCO enforcement, and a tag-triggered release workflow that packs the .mcpb and attaches build provenance.

Security

  • Strictly read-only. API keys stored in the OS keychain. No telemetry; the only outbound host is the broker API the user configures.
