Antigravity & Gemini Memory in Philadelphia
The agentic future is multi-model. Whatever Google ships next, your project memory stays put — versioned, permission-checked, and reachable through standard MCP rather than a vendor format.
Google Antigravity and Gemini CLI bring Gemini-grade reasoning to your repository — with the same amnesia as every other agent. MemHub supplies the durable memory layer over MCP that makes their output consistent week over week.

Why Philadelphia engineering teams choose MemHub
In Philadelphia, software teams ship faster when their tools share one memory instead of three silos. Distributed squads stay aligned because every session opens with the same briefing.
MemHub runs hosted or fully self-hosted, so the storage boundary follows your compliance requirements rather than dictating them.
- Philadelphia: connect Claude Code, Cursor, Windsurf, Cline, Codex CLI, or Antigravity to one shared memory. It also plugs into any CLI that speaks MCP or reads a JSON config.
- Local-first writes keep sessions productive through outages and travel.
- One command onboards the whole team: memhub login, then connect for Claude Code, Cursor, Windsurf, Cline, Codex CLI, or any JSON client.
UNIVERSAL COMPATIBILITY
Plugs into any CLI or development tool you use.
If it speaks MCP or reads a JSON config, MemHub plugs in. One command wires the majors; everything else joins as a generic client.
- Claude Code
- Cursor
- Windsurf
- Cline
- Codex CLI (GPT)
- GitHub Copilot
- Google Antigravity
- Gemini CLI
- Aider
- OpenCode
- CI bots via REST
WHAT YOU GET
Antigravity & Gemini Memory in Philadelphia, without the trade-offs.
01
Team provenance
Authorship and source links keep agent context accountable.
02
Offline outbox
Local SQLite queues writes through connectivity gaps and syncs safely after.
03
Scoped credentials
Per-project keys with roles and instant revocation.
04
MCP-first
Antigravity and Gemini CLI consume Model Context Protocol servers; MemHub plugs straight in.
05
Multi-model ready
The same memory serves Gemini, Claude, GPT, and local models without duplication.
06
Incremental briefings
Sessions receive deltas since their last sequence — never a stale dump.
The honest comparison.
No feature-matrix gymnastics — just what changes the week you adopt MemHub.
| Status quo | With MemHub |
|---|---|
| Context lives in heads and DMs | Memory is structured, shared, and searchable |
| Every agent re-learns the repo | Sessions open pre-briefed with only what changed |
| Rules files cap out at ~2k tokens | Unbounded versioned history stays one query away |
Connect the tools already in your repository.
One command injects configuration for Claude Code, Cursor, Codex CLI, Google Antigravity, Windsurf, Cline, or any JSON MCP client.
repository terminal
$ npm install --global @simplexlat/memhub
$ memhub login
✓ project resolved · context ready · memory synchronized
Questions, answered straight.
What about Gemini CLI?
Gemini CLI reads the same JSON MCP config shape; the connect command writes it for you, or select it as an “other” JSON client.
Does Google Antigravity support MCP servers?
Yes — Antigravity is built around the Model Context Protocol. Point its MCP configuration at the memhub proxy and restart.
What happens when our connection drops?
Nothing interrupts the work. Writes commit to the local SQLite outbox and synchronize automatically when the shared service is reachable again.
Can we try it without sending data anywhere?
Yes — the local engine works fully offline, and the self-hosted stack keeps even the shared layer on your own PostgreSQL.
How much does it cost?
A Community tier is free, and the Team plan adds multi-project contexts, seats, and higher synchronization limits. Self-hosting is unlimited.
