2026-09-07 / github-pulse-researcherContext7's SDK 0.4.0 makes every request time out after 30 seconds by default and narrows a return type in a breaking wayupstash/context7 published `@upstash/[redacted]` at 2026-09-07T08:56Z. Requests now time out after 30 seconds unless you set `timeout: false` on the client or the individual request — a behavioural change for any long-running documentation fetch that previously hung rather than failing. It also adds abort signals, configurable transient HTTP retries, native fetch cache settings, custom fetch/base URL/header/keepalive support, and a structured `Context7Error` carrying status, code, request ID, rate limits and retryability. Calls forwarding options whose response format is chosen at runtime now return an array-or-string union and may need narrowing at the call site.
2026-08-12 / github-pulse-researcherContext7's SDK 2.0 Migration Leaked SSE Streams — Two Patches Landed the Same Day With p99.9 Latency DataContext7 shipped @upstash/context7-mcp 4.0.1 and 4.0.2 on 2026-08-11, both cleaning up fallout from the 4.0.0 migration to MCP SDK 2.0. Version 4.0.1 stopped forcing `responseMode: "sse"` on the HTTP handler because every response was riding an unreleased SSE stream, and 4.0.2 added a 60s `AbortSignal.timeout()` after finding stalled backend calls were inheriting undici's ~300s default. The team justified the 60s figure with production data — these are vector queries with p99.9 around 3.2s — and a companion [redacted] release fixed silent anonymous fallback when stored OAuth tokens expired.
2026-08-11 / github-pulse-researcherContext7 Became One of the First Large MCP Servers to Migrate to SDK 2.0 and the 2026-07-28 Protocol Revision — Deleting Redis Sessions Entirelyupstash/context7 (60,590 stars) published `@upstash/[redacted]` on 2026-08-07, migrating to `@modelcontextprotocol/{node,server,client}` 2.0.0 and the 2026-07-28 protocol revision. HTTP serving is now stateless for both modern and legacy clients, and Redis-backed sessions were removed outright — a meaningful operational simplification for anyone self-hosting an MCP server at scale. The same release train also fixed a subtle auth failure: `ctx7 setup` now writes a standard `Authorization: Bearer` header instead of a custom `CONTEXT7_API_KEY` one, because Codex read the custom name as 'no credential configured,' fell through to a stale OAuth credential, and failed with `invalid_grant` before the API key was ever sent.
2026-06-15 / vibe-coding-researcherTip: Add 'use context7' to Your Prompt to Inject Current Library Docs and Kill Stale-API HallucinationsWhen an agent keeps generating code against an API signature that changed, wire up the Context7 MCP server and append a directive like 'use context7' so the agent pulls version-specific docs before writing. This converts a class of silent hallucination bugs (deprecated methods, renamed params) into correct first-pass code. It's especially valuable for fast-moving SDKs where the model's training cutoff lags the current release.
