How to run each

agent-antigravity

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

Noosphere As a local MCP server: PyPI package

Claude Code

claude mcp add --env "GITHUB_TOKEN=<YOUR_GITHUB_TOKEN>" --transport stdio noosphere -- uvx noosphere-mcp

Requires: GITHUB_TOKEN (secret)

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

Only agent-antigravity asks for

GEMINI_API_KEY (secret)

Only Noosphere asks for

NOOSPHERE_MCP_PROFILE
NOOSPHERE_REPO

Settings as each marketplace publishes them. Asking for fewer is not better in itself.
