v0.1.2: mcp-ts-core 0.12.3 / SDK v2 adoption, error-contract reclassification

mcp-ts-core 0.12.3 / SDK v2 adoption, error-contract reclassification

• Framework ^0.10.6 → ^0.12.3 (MCP SDK v2): protocol revision 2026-07-28 served alongside the 2025 era, strict tool inputs, error envelope declared in outputSchema, ctx.log reaches clients, Retry-After honored
• unsupported_currency and unknown_category now return NotFound (-32001); invalid_range returns ValidationError (-32007)
• Docker build stage pinned to $BUILDPLATFORM so linux/amd64 images build natively instead of under QEMU; bun 1.4.0 base, BuildKit cache mounts, --omit=peer production installs
• Internal: supply-chain install guard (minimumReleaseAge + Socket scanner), community health files, websiteUrl dropped from createApp identity, protocol docs and README badges synced
• deps: @cyanheads/mcp-ts-core ^0.10.6 → ^0.12.3, typescript ^6.0.3 → ^7.0.2 (+ @types/node 26.2.0, vitest ^4.1.11, @biomejs/biome 2.5.9)

CHANGELOG v0.1.2

v0.1.1: Metadata correctness

Metadata correctness

Changed:

• README <h1> now reads @cyanheads/coingecko-mcp-server, mirroring the published npm package name.

Added:

• repository field in manifest.json pointing at the GitHub repo.

44 tests pass; bun run devcheck clean.

v0.1.0: Initial release — CoinGecko market-data MCP server

Initial release — CoinGecko market-data MCP server

Cryptocurrency market data via the live CoinGecko v3 REST API. Read-only, keyless by default; optional COINGECKO_API_KEY attaches the Demo-tier header.

Added:

• 8 tools: coingecko_search_coins, coingecko_get_prices, coingecko_list_markets, coingecko_get_coin, coingecko_get_market_chart, coingecko_get_trending, coingecko_get_global, coingecko_list_categories
• 2 resources: coingecko://coin/{id}, coingecko://global
• coingecko_coin_research prompt — guides the search → get_coin → get_market_chart → get_global chain
• COINGECKO_API_KEY optional env var (x-cg-demo-api-key header); keyless public tier by default
• CoinGecko service — one method per endpoint, fetch+parse wrapped in withRetry (429/5xx/timeout); 404 surfaces as typed coin_not_found. Every output carries CoinGecko attribution.

44 tests pass; bun run devcheck clean.
