Context Mode vs Context+

Choosing between Context Mode and Context+? Both are ai tools MCP servers, but they lean into different workflows. This page focuses on where each one is actually stronger, not just raw counts.

Choose Context Mode for

Managing large log files or API responses without exhausting the LLM context window.

Choose Context+ for

Performing deep code discovery in large, unfamiliar codebases.

The other half of the context problem.

Context Mode is not a CLI output filter or a cloud analytics dashboard. It operates at the MCP protocol layer — raw data stays in a sandboxed subprocess and never enters your context window. Web pages, API responses, file analysis, Playwright snapshots, log files — everything is…

What it does

  • Reduces context window usage by intercepting and summarizing raw tool output.
  • Maintains session continuity by indexing events in a local SQLite database.
  • Operates in a sandboxed subprocess to ensure data privacy.
  • Provides BM25 search to retrieve only relevant historical session data.
  • Supports automatic routing enforcement for Claude Code.

Available tools (6)

ctx_batch_executeExecutes multiple commands in a sandboxed environment while keeping output out of the context window.
ctx_executeExecutes a single command in a sandboxed environment.
ctx_execute_fileExecutes a file in a sandboxed environment.
ctx_indexIndexes data into the local SQLite database for future retrieval.
ctx_searchPerforms a BM25 search against indexed session data.
ctx_fetch_and_indexFetches external data and indexes it immediately.

Semantic Intelligence for Large-Scale Engineering.

Context+ is an MCP server designed for developers who demand 99% accuracy. By combining RAG, Tree-sitter AST, Spectral Clustering, and Obsidian-style linking, Context+ turns a massive codebase into a searchable, hierarchical feature graph.

What it does

  • Hierarchical feature graph generation using Tree-sitter AST
  • Semantic code search and navigation via spectral clustering
  • Blast radius analysis for impact assessment of code changes
  • Shadow restore points for safe AI-driven code modifications
  • Graph-based memory management for codebase concepts and relations
