Each figure is the marketplace's own and is never added up across marketplaces. A marketplace that publishes no figure shows none: no number is not zero.

Its card, with similar plugins by marketplace

What each says it does

bOpen Core

In its own words, on Community GitHub marketplaces:

Cross-agent development skills, hooks, orchestration, and optional custom-agent adapters for Claude Code, Codex, and Grok Build

Orchestrator

In its own words, on Official MCP Registry:

Let one coding-agent CLI consult another: Codex, Claude Code, OpenCode, Copilot or Antigravity.

How to run each

bOpen Core

No data for an automatic command: what its marketplaces declare does not say unambiguously how to connect it.

Orchestrator As a local MCP server: PyPI package

Claude Code

claude mcp add --env "ORCHESTRATOR_CONFIG=<YOUR_ORCHESTRATOR_CONFIG>" --env "ORCHESTRATOR_HOST_RUNTIME=<YOUR_ORCHESTRATOR_HOST_RUNTIME>" --transport stdio orchestrator-mcp -- uvx orchestrator-mcp-server

Requires: ORCHESTRATOR_CONFIG, ORCHESTRATOR_HOST_RUNTIME

Commands built only from what the marketplaces declare; the full set for every client is on each card.

Tools each declares

Neither one's marketplaces publish a list of tools, so there is nothing to compare.

Settings each asks for

The marketplaces of bOpen Core publish no settings it asks for, so we do not compare settings.
