v0.8.1
SQD Portal MCP v0.8.1 makes blockchain investigations more dependable under empty results, invalid inputs, upstream failures, and client cancellation.
Highlights:
- stable structured tool errors with bounded codes, origins, retry guidance, and next steps
- explicit data, empty, partial, error, and cancelled outcomes across all 28 tools
- HTTP cancellation that closes active upstream work and supports immediate recovery
- bounded Portal retries without invalid-request amplification
- privacy-safe metrics that never capture forwarded user questions or arbitrary client headers
- synchronized SQD packages for Codex, Claude, Grok Build, Gemini CLI, and Cursor
- clearer pagination, coverage, freshness, ordering, and evidence paths across network and analytics tools
Authentication remains deferred to the unified v0.9.0 flow.
