Self-Hosted Memory for AI Agents: What It Takes

Description and use

Developers can self‑host AI agent memory by choosing among four options—repo files, local MCP server, Postgres+embeddings, or hosted ContextForge—each with distinct trade‑offs for data residency, tooling, and maintenance.

Problem

Developers need a memory layer that saves decisions with reasons, recalls by meaning, and flags staleness, without relying on external services.

Outcome

Teams can self‑host agent memory at varying complexity levels, ensuring data residency and control while maintaining the core memory functions of decision saving, semantic recall, and staleness detection.

Workflow

• Identify the team’s data residency and tooling requirements
• Select the appropriate self‑hosting option from the four listed
• If using the hosted path, run npx contextforge-mcp init to link the repo
• Add hooks to reload context after Claude Code compacts
• Save decisions with clear reasons using the memory API
• Agents automatically recall relevant notes and detect staleness

Evidence

Self-hosted memory for AI agents sounds like a database problem, and the database turns out to be the easy part.

Source

The MCP server you install is open source. The storage behind it is not something you can run on your own machine today.

One command, in the repo you're working on: npx contextforge-mcp init
