What is the key difference between Memex and Hindsight?

Memex belongs to the Knowledge & Memory category with local stdio execution, while Hindsight belongs to the Knowledge & Memory category with local stdio execution.

How do I install Memex or Hindsight in Claude Desktop or Cursor?

Copy the mcpServers JSON configuration snippet provided on this page into your claude_desktop_config.json or ~/.cursor/mcp.json file and restart your AI client.

Are Memex and Hindsight free or paid?

Memex operates under a Free / Open Source model (No auth required). Hindsight operates under a BYOK (Pay Provider Direct) model (API Key required).

Which MCP server has more tools and community activity?

Memex lists 6 tools with 3 views and 1 GitHub stars. Hindsight lists 6 tools with 3 views and 19,332 GitHub stars.

Can I use both Memex and Hindsight together in the same MCP host?

Yes! MCP hosts like Claude Desktop, Cursor, Windsurf, Cline, and VS Code support configuring multiple servers under the mcpServers object simultaneously.

How do I install Memex or Hindsight in Claude Desktop, Cursor, or Windsurf?

Both servers follow the standard Model Context Protocol configuration format. Simply copy the JSON block from the configuration section above and paste it into your AI client's mcpServers configuration object (for instance in claude_desktop_config.json or ~/.cursor/mcp.json ), then completely restart or refresh the application.

Are Memex and Hindsight free to use, or do they require API keys?

Memex is listed under a Free / Open Source model with No auth required . Hindsight operates under a BYOK (Pay Provider Direct) model with API Key required . If environment variables are required (such as API keys), be sure to define them under the env key in your MCP client's configuration file.

Can I run both Memex and Hindsight at the same time in my AI client?

Yes! MCP clients support multi-server orchestration. You can include both ayushagrawal288-memex and vectorize-io-hindsight as distinct keys inside the single mcpServers object in your configuration file. Your AI assistant will automatically select and call the appropriate tool from either server during chat sessions.

Which MCP server has higher directory engagement and quality ratings?

On AllMCPs, Memex has a Quality Score of 43 /100 ( Fair ) with 3 views, 0 installs, and 1 GitHub stars. Hindsight holds a Quality Score of 53 /100 ( Good ) with 3 views, 0 installs, and 19,332 GitHub stars.
