Second Brain for AI
Rahil Patel
Self-hosted persistent memory layer that lets Claude, ChatGPT, Cursor, and any MCP client share the same evolving context.
Key features
- Cross-Tool Persistent Memory: One memory layer shared by Claude, ChatGPT, Cursor, Codex, and any MCP client.
- Semantic Recall: Retrieves memories by meaning rather than exact wording, so different phrasings still surface the right note.
- Memory Graph (v2): Memories link automatically or explicitly, and recall can follow hops to surface related context.
- Notion Sync: Connect a Notion workspace and shared pages sync into memory nightly or on demand, staying current as they change.
- Self-Hosted on Cloudflare Workers: Deploy to your own account in about two minutes — memory stays under your control, not a vendor's.
- MCP Tool Set: remember, append, update, recall, list_recent, forget — usable directly from any MCP client or the brain CLI.
- Graceful Degradation: If Vectorize is missing, recall falls back to keyword search with a clear notice and a /health endpoint reports index status.
- Dashboard with Graph View: Web dashboard for browsing memories, managing integrations, and exploring the memory graph visually.
Best for
- Consistent Assistant Context: Keep the same project background, preferences, and decisions across Claude, ChatGPT, and Cursor without repeating yourself.
- Team Knowledge Capture: Use the CLI or MCP tools to store product decisions or interview notes so any AI tool can recall them later.
- Notion-Backed Memory: Share Notion pages with the connection so meeting notes and specs are automatically retrievable by any AI client.
- Self-Hosted Compliance: Run memory in your own Cloudflare account when data cannot leave your infrastructure or be locked in one AI platform.
- Developer Journaling: Save decisions and rationale from your terminal (`brain remember`) and recall them from Cursor while coding.
- Research Continuity: Store leads, references, and open questions once and surface them across whichever assistant you're using that day.

Toolport
Toolport
Free open-source local MCP gateway. Set up each server once and share it across Claude, Cursor, VS Code, Codex, Windsurf.
Key features
- Universal MCP gateway: Set up any MCP server once and every agent (Claude, Cursor, VS Code, Windsurf, Codex, Antigravity) shares it with hot toggles and no restarts.
- Lazy tool discovery: Exposes a handful of meta-tools instead of dumping hundreds of tool definitions, cutting tool-definition tokens 74–91% at the same task success on a frontier model.
- Tool integrity checks: Fingerprints every tool and flags rug-pulls (a definition changing after approval) and tool poisoning (hidden instructions in descriptions), on by default and entirely local.
- Keychain secrets: API keys live in your OS keychain and are injected at runtime — never in a config file, never in the cloud.
- Per-tool governance: Toggle any tool on or off with one switch to hide destructive tools from every agent fleet-wide.
- Live observability: Per-server latency, error rates, and a full audit trail of every tool call built into the app.
- Cross-platform local runtime: Runs on Windows, macOS, and Linux with no account and no cloud dependency, released under the MIT license on GitHub.
- Toolport for Teams: Shared governed set of MCP servers for a whole team (free for up to 5 people) while each person's API keys stay on their own machine.
Best for
- Individual AI power users running Claude, Cursor, and Codex who want a single place to configure MCP servers instead of pasting the same setup into each agent.
- Engineers hitting context-window limits from bloated tool-definition tokens who need lazy discovery to keep long agent sessions cheap and sharp.
- Security-minded developers who need API keys stored in the OS keychain and cryptographic integrity checks against tool poisoning and definition rug-pulls.
- Small teams (up to 5 people) who want one governed catalog of MCP servers while keeping each engineer's credentials on their own machine.
- Agent-tooling authors who want a local audit trail of latency, error rates, and every tool invocation across servers for debugging.
- Ops leads applying per-tool governance to hide destructive actions (writes, deletes) from every agent with a single fleet-wide toggle.
