Developer Tools / AI Safety / MCP Security
Open-source MCP proxy that blocks agent send/share actions when the destination first appears in untrusted tool output. It uses deterministic rules rather than an LLM and logs every allow/deny decision.
The page clearly describes a real AI-adjacent developer tool with a specific security purpose: an MCP proxy that protects agents from sending data to destinations lifted from untrusted tool output. The snapshot includes concrete behavior, quickstart usage, supported workflows, logging/audit details, and a stated limitation/status, which is enough for a useful public listing.
The page does not show broader platform support beyond MCP over stdio, and it is still early-stage v0.1.4. Visitors also cannot tell how well it performs across different clients or how much setup is needed in real deployments beyond the shown quickstart.

CodeGraph is a local code knowledge graph for AI coding agents like Claude Code, Cursor, Codex, OpenCode, and Hermes Agent. It aims to cut token use, tool calls, and runtime by letting agents query pre-indexed code structure instead of scanning files repeatedly.
Mercemur is a store automation platform with three interfaces: a REST API, an MCP server for AI agents, and a CLI for editing storefronts as files. The docs show authentication, scopes, rate limits, error handling, pagination, idempotency, and a large API surface for catalogue, orders, customers, pricing, and money.
Lumae is a free native macOS screen recorder and screenshot tool for polished demos, with automatic zooms, cursor smoothing, motion blur, captions, voiceover, and annotated screenshots. It also exposes editing commands over MCP so agents like Claude Code or Claude Desktop can edit projects directly.
A zero-dependency C++23 CLI and MCP server that gives coding agents a ranked map of a repository, including call context, blast radius, and tests to run.
