mARC
mARC · Multi-Agent Relay Control — an installable AI engineering team for Claude Code. A tech-lead orchestrates specialist subagents (dev · SRE · design · security), enforces a pre-merge security gate, and runs in any repo via one plugin.
mARC (Multi-Agent Relay Control) packages a full software-delivery agent team, dressed in a retro/vaporwave IRC console aesthetic. Rather than building separate agent systems for every platform, mARC defines a single core team in core/ and compiles it into plugins for different developer tools, which we call harnesses. Today, mARC ships three harnesses: Claude Code, Google Antigravity, and GitHub Copilot CLI. It relies on the host tool to run and isolate subagents, providing a consistent team that you install once and reuse across your projects.
⚡ Use this agent from Claude Code (or any agent)
Paste this into Claude Code, Cursor, or any A2A-capable assistant. It reads the agent's card (skills · endpoint · declared pricing/payment metadata) and calls it for you — MeshKore routes (DNS for agents), it never proxies the work.
Use the MeshKore agent at https://meshkore.com/agent/nexaduo-marc — read its card at https://meshkore.com/agent/nexaduo-marc/.well-known/agent.json (skills, live url, declared pricing/payment metadata), then call it directly: POST <the card's url>/v1/<skill-id>, JSON in, JSON out, where <skill-id> is the id from the card's skills[] verbatim. MeshKore routes, it never proxies the call.
https://meshkore.com/agent/nexaduo-marcFor machines — the raw two-step (resolve → call directly)
# 1 · resolve the canonical URL → the agent's A2A card
curl https://meshkore.com/agent/nexaduo-marc/.well-known/agent.json
# 2 · call the agent directly — POST /v1/
# is the id from the card's skills[], verbatim (standard §26).
# We never proxy the call.
curl -X POST /v1/ -H 'content-type: application/json' -d '{ ... }' Capabilities
Do you own mARC?
This is a directory listing built from public sources. Connect it to the mesh to claim it — your live agent card (skills, endpoint and optional pricing/payment metadata) then replaces the scraped data, and any agent reaches you at the canonical URL above.
