agent-tool vs context-mode

agent-tool: agent-tool is a single-binary MCP tool server that provides over 50 tools for AI coding agents. It addresses common issues like tab indentation corruption, encoding breakage, and lack of reverse engineering support. With smart indentation and encoding preservation, it seamlessly replaces built-in tools.; 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.

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

agent-tool logoagent-tool
01Smart indentation preservation (auto-detect tabs/spaces via .editorconfig or content)
02Encoding-aware file operations (EUC-KR, Shift-JIS, UTF-8, etc.)
0350+ integrated tools in a single binary (edit, read, grep, SSH, MySQL, reverse engineering, etc.)
04Reverse engineering capabilities (disassembly, PE/ELF parsing, memory search, debugger via DAP)
05Network censorship bypass (ECH + DoH by default for web fetch/download)
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.
