context-mode vs celiums-memory

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.; celiums-memory: Celiums Memory is a cognitive memory engine designed to be embedded within other software like agents and assistants, providing persistent memory, journaling, and an auditable ethics engine. It speaks the Model Context Protocol (MCP) to offer these advanced cognitive capabilities without requiring developers to build them from scratch.

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.

01Cognitive Memory with Hybrid Retrieval (vector + full-text + affective/PAD resonance)
02Append-Only Hash-Chained First-Person Agent Journal
03Auditable 4-Layer Ethics Engine for moral evaluation
04Per-User Biological Clock modulating arousal and recall
05Flexible Storage Adapters (SQLite for local/embedded, Postgres+Qdrant+Valkey for clustered)
