 - [2ools/mcp-server](https://github.com/2ools/mcp-server) [![2ools/mcp-server MCP server](https://glama.ai/mcp/servers/2ools/mcp-server/badges/score.svg)](https://glama.ai/mcp/servers/2ools/mcp-server) 🎖️ 📇 ☁️ 🍎 🪟 🐧 - Turn what your assistant just built into a durable, versioned project. One free authless tool (`create_public_preview`) renders a standalone HTML document as a real shareable URL; 42 more cover projects, refinement, version comparison, separately-delegated approvals, artifacts, work assignments and source export. Build authority and review authority are deliberately separate scopes. Remote Streamable HTTP, OAuth 2.1 + PKCE. `https://2ools.app/mcp`

Same-instant races elect exactly one winner; late duplicates replay a sealed, content-addressed receipt (fence_prepare / fence_commit / fence_abort). Ships a 1,000-attempt storm demo enforced in CI. `npx -y effectfence` (prebuilt binaries for macOS, Windows and Linux — no Rust toolchain) or `cargo install effectfence`.

Read-only, five tools, zero runtime dependencies. `npm i hono-telescope`, then `claude mcp add --transport http telescope http://localhost:3000/telescope/mcp`.
