Agent-Reach: Give AI Agents Access to Web Sources
Agent-Reach is a Python CLI that helps AI agents read and search across websites and platforms such as YouTube, Reddit, GitHub, and Twitter. It installs and checks integrations, with some sources available immediately and others requiring login or configuration.
open-pencil: Edit and Automate Design Files
OpenPencil is an AI-assisted design editor for opening and editing .fig and .pen files. It combines a visual canvas with CLI, MCP, and scripting tools for design workflows, plus real-time collaboration and a headless Vue SDK.
palmier-pro: Edit Video with AI on macOS
Palmier Pro is a Swift-native macOS video editor that combines timeline editing with generative AI and MCP access for AI agents. It suits creators who want to generate or edit media alongside agent-assisted workflows on Apple Silicon.
codebase-memory-mcp: Build a Searchable Code Knowledge Graph
A local MCP server that indexes repositories into a persistent graph of code structure and relationships. It helps AI coding agents answer architectural and code-navigation questions with focused queries instead of repeated file searches.
synara: Manage Coding Agents in a Desktop Workspace
Synara is a local-first desktop workspace for coordinating coding-agent sessions with project files, terminals, previews, and Git review. It suits developers who want to run locally installed agent providers and keep execution and review in one place.
deliberation: Get Multi-Model Reviews and Consensus
Deliberation is an MCP server and coding-agent plugin that routes plans and code questions to external AI models for second opinions or arbiter-mediated consensus. It suits developers who want independent reviews before making consequential changes.
warpchart: Track GitHub Repository Growth and Rankings
Warpchart turns GitHub star data into live growth telemetry, showing repository rankings, velocity, neighbors, and milestones. It suits maintainers who want a hosted dashboard, embeddable charts, or a self-hosted tracker for a repository.
mcp-grafana: Connect AI Clients to Grafana
Grafana’s MCP server lets compatible AI clients access Grafana dashboards, data sources, alerts, incidents, and other stack features through the Model Context Protocol. It suits teams that want to bring Grafana context and selected operations into agent workflows.
engram: Give AI Coding Agents Persistent Memory
Engram is a Go-based memory system that helps AI coding agents retain useful project knowledge between sessions. It stores memories locally in SQLite and makes them available through MCP, a CLI, an HTTP API, and a terminal UI.
GitNexus: Map Codebases for AI-Assisted Analysis
GitNexus indexes a codebase as a knowledge graph and exposes its relationships through CLI and MCP tools. It helps developers and AI coding agents trace dependencies, understand execution flows, and assess change impact.
OpenHuman: Run a Modular AI Agent Harness
OpenHuman is a Rust-based agent harness available as a desktop app, browser UI, terminal client, and embeddable library. It connects configurable language models, memory, search, tools, and workflows for people building or using persistent AI agents.
agentmemory: Persistent Memory for AI Coding Agents
agentmemory gives coding agents persistent, searchable memory across sessions and tools. It captures work through agent integrations and exposes shared memory through MCP and REST, with a local-first runtime built on iii-engine.
