context-mode vs perseus-vault

context-mode: Every tool call in an MCP (Model-Controller-Program) environment dumps raw data into the context window, quickly consuming space and causing the agent to lose track of ongoing tasks. Context Mode is an MCP server that tackles this by sandboxing tool outputs to significantly reduce context usage, tracking session events in SQLite for continuity, and promoting 'think in code' to minimize data processing within the LLM.; perseus-vault: Perseus Vault provides durable, encrypted, local-first memory for AI agents, operating as a single Rust binary with zero dependencies. It integrates seamlessly with popular AI agent frameworks like LangGraph, CrewAI, and AutoGen, offering advanced features like hybrid semantic search, bitemporal queries, and a robust memory lifecycle.

TL;DR

context-mode logo
context-modeMemory & Context · ★ 31.8k
When to choose:
  • Your sessions fill up with tool output such as Playwright snapshots, GitHub issue lists or logs.
  • You want work state (edits, git operations, tasks, decisions) to survive context compaction without being dumped back into the window.
  • You use a hook-capable agent, where tool routing happens automatically.
When to skip:
  • You need an OSI open-source licence: it uses the Elastic License 2.0, which restricts uses such as offering it as a managed service.
  • Your sessions are short and rarely hit the context limit.
  • You do not want hooks changing how your agent's tools behave.

Features

context-mode logocontext-mode
01Context Saving: Sandbox tools keep raw data out of the context window, achieving up to 98% reduction.
02Session Continuity: Tracks every file edit, git operation, task, and user decision in SQLite for seamless session resume.
03Think in Code: Promotes LLMs to program analysis, not compute it, saving 100x context by logging only results.
04Batch Execution & Search: Run multiple commands/queries in one call with tools like `ctx_batch_execute`.
05Advanced Knowledge Base: Uses SQLite FTS5 with BM25 ranking, smart snippets, and TTL cache for efficient information retrieval.
perseus-vault logoperseus-vault
01Bundled semantic search with zero configuration and network dependencies.
02Biomimetic memory lifecycle with Ebbinghaus decay, layer promotion, and automatic archiving.
03AES-256-GCM transparent encryption for stored entity data.
04Recall-first context injection with relevance gating and per-model budget.
05Multiple transport options including stdio, SSE, and HTTP for MCP clients.
