MCPg v0.6.8 — release notes

Released: 2026-07-05 Tool surface: 252 tools across 19 capability buckets Tests: 2746 pass (PG 14 / 15 / 16 / 17 / 18 / 19 / WarehousePG) Runtime: Python 3.14

This is a patch-level bump (0.6.7 → 0.6.8) focused entirely on adoption: installing MCPg into any MCP client is now a one-click or one-snippet affair. No tool signatures changed; everything is backward-compatible.

Headline: one-click installs, everywhere

• Claude Desktop — this release attaches the first mcpg-<version>.mcpb desktop-extension bundle: download, double-click, paste your connection URL (stored in the OS keychain), done. The bundle is ~2 kB and works on every platform/architecture — it uses the MCPB uv server type, so Claude Desktop resolves the pinned mcpg release from PyPI at install time. Access mode defaults to read-only.
• Cursor and VS Code — one-click install badges in the README, via the official HTTPS deeplink endpoints. The VS Code install prompts for the connection URL as a masked input, so it never lands in plain-text settings.
• Everything else — the new client integrations guide covers 14 clients with copy-paste configs: Windsurf, JetBrains AI Assistant, Cline/Roo Code, Zed, Google Antigravity (+ Gemini CLI), Qwen Code, Perplexity, ChatGPT (remote connectors), Microsoft Copilot Studio, Continue, Claude Code CLI, and generic streamable-HTTP clients — plus a straight answer on Aider (no native MCP support upstream yet) and DeepSeek (a model provider whose models drive MCPg through these clients).

Directory-ready metadata

Rounding out v0.6.7’s readOnlyHint work, every tool now also carries:

• a human-readable title, auto-derived from the tool name with an acronym/product-name table (recommend_ivfflat_probes → “Recommend IVFFlat probes”), and
• an explicit destructiveHint on all 67 write-capable tools, from a curated destructive (18) / non-destructive (49) partition. A contract test requires the partition to cover the write surface exactly, so a new write tool cannot ship unclassified.

Together with the new PRIVACY.md (self-hosted, no telemetry, one documented external call), MCPg now meets the published metadata requirements for connector-directory listings.

Also fixed

• GitHub Release bodies had shipped the “See CHANGELOG.md” stub on every release since automation was added — an awk range-pattern bug in the extraction step. This release is the first with the fix in effect; the body you’re (hopefully) reading it in came from the changelog.

Upgrade

pip install --upgrade mcpg
docker pull ghcr.io/devopam/mcpg:0.6.8   # or :latest

Or grab mcpg-0.6.8.mcpb from this release and double-click it into Claude Desktop. No configuration changes required.
