Asymptote Labs · Agent Memory Layer

Beacon

An open-source memory and trace layer for AI coding agents, written in Go. It captures full session history across Claude Code, Cursor, Codex, OpenCode, Cline and more than 20 other harnesses, including prompts, tool calls, commands, edits, approvals, MCP activity and tokens, in one OpenTelemetry-based event model, then serves reviewed workflows, corrections and repo conventions back to future agents over MCP or Agent Skills. This week added beacon mcp connect to register its MCP server in harness configs, git commits linked to the agent sessions that wrote them, and threat rules v1.1 for spotting secret reads and indirect prompt injection. Local-first, though setup preselects the hosted option. MIT, 1,755 stars, v1.3.29 on 28 September.
