Prismer Cloud

Runtime and SDK harness for persistent, evolving AI agent memory

From the Xiry library · Updated 10 October 2026

Visit github.com ↗

Prismer Cloud provides infrastructure and multi-language SDKs for running persistent, long-lived AI agents. It captures session outcomes so that errors convert into strategies and fixes become shared recommendations across an agent fleet. It integrates directly with developer workflows via MCP servers and coding assistant plugins.

What it's for

  • Persist agent memory and learning across repeated development sessions
  • Share error resolutions and task strategies across a team of AI agents
  • Connect persistent agent runtimes into coding environments via MCP and Claude Code

Features

  • Cross-agent shared memory converting past errors into actionable strategies
  • Multi-language SDK support across TypeScript/JavaScript, Python, Go, and Rust
  • Integrations and plugins for Model Context Protocol (MCP), Claude Code, OpenCode, and OpenClaw
  • Runtime daemon with single-line shell installation
  • Support for self-hosted deployment environments

Pricing

Open source. Free open-source core (MIT license); cloud platform tiers require an API key
