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.

A lightweight React Markdown renderer with built-in LaTeX, syntax highlighting, streaming-safe rendering, and security-focused defaults.

An open-source SAS 9.4-compatible interpreter written by agents, with a browser playground, tests, and real clinical-programming pipeline support.

Open protocol for agent-consumable job feeds with MCP-native tools, discovery manifests, schemas, and a live API playground for job search and application flows.

An OWASP incubator project that protects AI agent memory from prompt injection, secret leakage, and tampering. It includes a Python library, policy-based controls, benchmarks, and integrations for agent frameworks like LangChain and AutoGen.

CLI for catching AI-generated code smells and regressions in code. It scans changes with 40+ rules across 7 languages, offers fixes, CI gating, hooks, and MCP tools.

Managed desktop environments for computer-use agents, with application monitoring, artifact checkpoints, and recovery controls. The page shows KiCad and FreeCAD support, an API/SDK, usage flow, pricing, and a quickstart example.

A PostgreSQL helper that previews INSERT, UPDATE, and DELETE effects as row-level proposals before applying them, aimed at AI agents and other write workflows.

Knowl is a persistent memory server for AI coding agents. It stores facts with provenance, supports supersession when information changes, and integrates with clients like Claude Code, Cursor, and Codex through MCP.

Tako VM is a secure file system and Python execution layer for AI agents, with gVisor-isolated containers, queued jobs, retries, replay, and a Python SDK/REST API.

An MCP server and CLI for shared notebooks for agents, with pull/commit workflows, durable S3 storage, and text-based conflict handling.

A curated-taste API for architecture, art, design, and photography, with both REST endpoints and a native MCP server for AI agents. It offers search, similarity, provenance, and taste metadata across 2,500+ hand-selected projects, plus free keys and documented pricing.

LLMIntel is a runtime telemetry and cost dashboard for LLM apps. The live demo shows spend by model, API key, environment, and tag, plus at-risk spend for retiring models and optimization suggestions.

A free public API for LLM pricing, specs, benchmarks, and cost calculations across 1,000+ models. It offers no-auth endpoints, CORS support, an OpenAPI spec, and a LiteLLM-compatible cost map that refreshes daily.

A transparent MCP proxy and terminal UI for watching real client-to-server tool calls, inspecting frames, replaying captured calls, and debugging live JSON-RPC traffic.

An MCP server that gives AI agents access to 8,500+ curated awesome lists and 1.3M+ resources, with hosted and local setup options plus tool docs and example queries.

A Model Context Protocol server for Uptime.com that lets AI assistants manage monitoring checks, alerts, outages, status pages, and account usage through tools and hosted or self-hosted deployment options.

Local dashboard for Claude Code sessions with live monitoring, session history, usage charts, resume commands, and LLM usage analysis.

AI code review tool that scores code against six decay-risk dimensions inspired by twelve classic engineering books, with book citations, severity labels, and remediation guidance.

Crit is a local-first review tool for AI coding agents, letting users comment on plans and code diffs, iterate through multiple review rounds, and share reviews when needed. It supports several agent ecosystems and can be installed as a single binary.

Open Bias is an open-source reliability harness for LLM apps and agents that enforces rules at runtime. It sits between your app and an LLM provider, using RULES.md policies to trace, block, or fix off-policy behavior.

A React mini-arcade component for turning loading screens into playable one-button games while long tasks run. It includes multiple game modes, skins, score tracking, achievements, and simple props for embedding in apps.

grith is a Linux security proxy for AI coding agents that supervises file, process, and network actions at the OS level before they execute. It supports tools like Claude Code, Codex, Aider, Cline, and Goose, with local audit logging and profiles for common agent workflows.

unbox-ai is an open-source CLI and local viewer for inspecting AI agent traces. It visualizes token usage, latency, tool calls, and repeated context in a bundle-analyzer-style interface, and also includes read-only commands for agents and a live AI SDK DevTools mode.
