Zed

Long-term memory for the Zed editor's AI assistant, powered by Hindsight. One command connects Zed's Agent Panel to the Hindsight MCP server and adds a rule telling the agent to use it — so it recalls relevant memory at the start of a task and retains durable facts as it goes. Recall happens at query time against your actual message, and from your seat it's automatic.

How It Works

Zed has no pre-prompt hook, but it supports two things this integration uses:

• MCP context servers: Zed runs MCP servers configured under context_servers in settings.json and surfaces their tools in the Agent Panel. hindsight-zed registers the Hindsight MCP server there, giving the agent recall / retain / reflect tools.
• A global instructions file (~/.config/zed/AGENTS.md) that Zed includes in every conversation. The integration adds a small rule there telling the agent to recall first and retain what it learns.

Zed doesn't yet have native HTTP-MCP transport, so the server is connected through the mcp-remote stdio bridge (run via npx), which means Node.js must be installed.

Setup

pip install hindsight-zed
hindsight-zed init --api-token YOUR_HINDSIGHT_API_KEY --bank-id my-memory

init adds the hindsight MCP server to ~/.config/zed/settings.json and the recall/retain rule to ~/.config/zed/AGENTS.md. Restart Zed, open the Agent Panel, and the hindsight server should show a green dot.

Use a Hindsight Cloud key, or point at a self-hosted server with --api-url http://localhost:8888 (no token needed for an open local server). If your settings.json has comments (JSONC), init prints the entry to paste rather than rewriting the file — or run hindsight-zed init --print-only anytime.

Commands

Command	Description
hindsight-zed init	Add the MCP server + recall/retain rule
hindsight-zed status	Show whether the server + rule are configured
hindsight-zed uninstall	Remove the server + rule

Note

Recall and retain run through MCP tools the agent calls, guided by the always-on rule. This makes recall query-time precise (no lag), with the tradeoff that it relies on the agent following the "recall first" instruction rather than the editor enforcing it.
