Context Mode
Open-source MCP plugin that keeps raw tool output out of your AI coding agent's context window—free, local, ELv2.
Install the free plugin if you run Claude Code, Cursor, Copilot, Codex or Gemini CLI and care about token spend—it is a one-command install (npm i -g context-mode), runs locally with no account, and the vendor's own example of one repeated command costing 750,000 input tokens is the exact waste it targets. Teams already on the plugin can add Context Mode Insight at $20/seat/month for role-narrowed views and pattern detection on structural events only. If you don't use an MCP-compatible agent, or you want full source-code monitoring, this is the wrong tool—Context Mode never forwards code or prompts.

Skip Context Mode if your coding assistant isn't one of the 17 supported MCP adapters, or if you need an org view that includes source code, prompts or file content—the Platform forwards structural metadata only.
Team-level analytics sit behind the $20/seat/month Platform—without it, everything the plugin captures stays on each developer's machine and no one sees it.
The plugin is free and open-source, so per-developer cost is zero and the only paid surface is the $20/seat/month Platform for org visibility. That puts it well below most AI observability or developer-analytics seats. Compare it against doing nothing: if your agents re-send large tool output every turn, the unpaid version of that is your model bill.

About Context Mode
Context Mode is an MCP plugin for AI coding agents that attacks context bloat from the other direction: instead of tuning prompts or swapping models, it intercepts large tool output—gh issue list, grep results, file reads—before it ever enters the LLM context window, parks the raw data in a local FTS5 SQLite store on your machine, and lets the agent search that store only when it needs an answer. The vendor claims up to 98% context savings per session and roughly 30x fewer tokens, using an illustrative example where a single command re-sent across 50 turns costs 750,000 input tokens. The plugin runs entirely locally with no cloud, no telemetry and no account, is licensed under Elastic License 2.0, and supports 17 AI adapters including Claude Code, Cursor, Copilot, Codex, Gemini CLI, JetBrains Copilot, GitHub Copilot CLI, Antigravity CLI and Kiro. Install is one command: npm i -g context-mode. The vendor reports 331,200+ developers running it. For engineering organizations there is the Context Mode Platform at $20/seat/month, which layers opt-in event forwarding on top of the same plugin. The plugin already records structural events locally—tool name, file path, error counts, decisions—and Platform forwards only that metadata to a private org workspace over an authenticated channel. Source code, prompt content and file content never leave the developer machine. Onboarding is described as a single command with no new install. The first Platform solution is Context Mode Insight (live, v1.0), which gives role-narrowed dashboards for CTO, EM, IC, CISO, FinOps and DevOps, plus continuous pattern detection for capacity imbalance, error spikes and rework concentration, with findings ready by Monday morning. Context Mode also lists three roadmap solutions for 2026: Memory (long-term memory across sessions, teammates and projects), Audit (SOC2-ready compliance trail for the AI surface) and Cost (token spend x velocity per team). Choose the free plugin if you are an individual developer paying per token; consider the $20/seat Platform only if you are already running the plugin and need an org view.
Behind the Verdict
Context Mode is interesting because it argues the context problem has two halves, and almost everyone is working on the wrong one. Most tooling optimizes the prompt or picks a cheaper model. Context Mode instead keeps data from entering the window at all: it intercepts large tool output, writes the raw payload to a local FTS5 SQLite store, and lets the agent query that store on demand. The vendor's framing is that you get the same answers and the same work with roughly 30x fewer tokens, and it illustrates the bleed with a concrete case—a single command whose output is re-sent every turn, costing 750,000 input tokens over fifty turns. Even if you discount the headline 98% figure, the mechanism is sound: anything re-sent every turn compounds, and anything retrieved on demand does not. The plain strengths: it is free and open-source under ELv2, it runs entirely on your machine with no cloud, telemetry or account, install is one command, and it covers 17 adapters—Claude Code, Cursor, Copilot, Codex, Gemini CLI, JetBrains Copilot, GitHub Copilot CLI, Antigravity CLI, Kiro and eight more. That breadth matters because most developers do not standardize on one agent. The vendor also reports 331,200+ developers running it, and the free tier costs nothing to test. The honest constraints are structural, not hidden. First, it only helps if your agent speaks MCP—if your workflow is a chat window or a non-MCP IDE plugin, none of this applies. Second, the raw store lives on local disk, so it consumes machine storage. Third, team-level analytics require the $20/seat/month Platform, and until you opt in, everything stays per-developer; the Platform forwards only structural metadata (tool names, file paths, error counts), so if you want to inspect what code an agent touched, this is deliberately the wrong product. Fourth, the Platform surface you can buy today is narrow: Insight v1.0 is live, while Memory, Audit and Cost are 2026 roadmap items, so an org buying for SOC2 audit trail or FinOps reporting is buying ahead of delivery. Where it fits: individual developers on metered token budgets, and engineering orgs that want defensible numbers—productive session rate per engineer, retry waste per team—without new instrumentation on developer machines. Where it does not: non-developers, teams that need full source monitoring, and anyone whose coding assistant is outside the MCP ecosystem. Versus alternatives, Context Mode is not competing with prompt-compression tools or model routers; it sits one layer earlier, at the tool boundary, and its nearest comparison is doing nothing and paying the re-send tax every turn.

Real-world workflow fit
Concrete scenarios for the personas Context Mode actually fits — and what changes day-one when you adopt it.
Install with npm i -g context-mode, then keep working as usual—grep results, file reads and issue listings get intercepted and written to the local FTS5 store instead of being re-sent on every turn.
Outcome: Vendor-reported savings of up to 98% of context per session, with the agent pulling answers from the local store on demand rather than carrying raw output through the conversation.
Flip the single opt-in switch so structural events—tool name, file path, error counts, decisions—forward from each developer's plugin to the private org workspace over an authenticated channel, with no new install and no workflow change.
Outcome: Team-level dashboards for productive session rate and retry waste, scoped to team or org, with no source code or prompts leaving any machine.
Open Context Mode Insight v1.0 and read the same event stream through role-narrowed views while continuous detection surfaces capacity imbalance, error spikes and rework concentration.
Outcome: Findings are waiting by Monday morning; the CTO gets ROI, the EM sees who's stuck and the CISO sees the structural trail, without anyone translating between reports.
Use Cases
- Cut token spend in Claude Code sessions by keeping large tool output out of context
- Give CTOs and EMs a defensible ROI number for the AI tools their teams already run
- Detect retry waste and rework concentration per team without reading anyone's code
- See which engineers are stuck on blockers from capacity-imbalance patterns
- Roll out the plugin across a team with one opt-in switch and no new install
- Track productive session rate per engineer in self, team and org scopes
Limitations
- The plugin only helps where your coding agent speaks MCP; the vendor documents 17 supported adapters (Claude Code, Cursor, Copilot, Codex, Gemini CLI, JetBrains Copilot, GitHub Copilot CLI, Antigravity CLI, Kiro and eight more) and the list is finite.
- Raw tool output is stored in a local FTS5 SQLite store, so it consumes space on the developer's own disk.
- Team-level analytics require opting into the Platform, and the Platform forwards structural metadata only—tool names, file paths, error counts—so source code, prompts and file content are never available to the org view, even if you want them.
- Of the four Platform solutions listed, only Context Mode Insight is live (v1.0); Memory, Audit and Cost are dated 2026 and not yet available.

Where the pricing makes sense
The company stage and team size where Context Mode's pricing actually pencils out — and where peers do it cheaper.
The plugin is free and open-source, so per-developer cost is zero and the only paid surface is the $20/seat/month Platform for org visibility. That puts it well below most AI observability or developer-analytics seats. Compare it against doing nothing: if your agents re-send large tool output every turn, the unpaid version of that is your model bill.
Setup time & first value
How long it actually takes to get something useful out of Context Mode — broken out by persona, not the marketing-page minute.
Individual developers: one command. The vendor's install line is npm i -g context-mode, and it runs locally with no account, cloud or network, so first value lands in the first session. For the Platform, onboarding is described as a single opt-in command on machines that already run the plugin—no new install, no developer interruption—though the org view only becomes useful once events accumulate.
Switching to or from Context Mode
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From doing nothing: install the plugin with npm i -g context-mode and let it intercept large tool output that currently re-enters context every turn.
- →From per-developer ad hoc context trimming: switch to the local FTS5 store so the agent retrieves on demand instead of you manually pruning output.
- →From a non-MCP workflow: move to one of the 17 supported adapters—Claude Code, Cursor, Copilot, Codex, Gemini CLI and others—before the plugin can intercept anything.
- →From per-developer plugin use to org rollout: enable the Platform's single opt-in switch to forward structural events to a private workspace without reinstalling on each machine.
- ↗To a cloud-only agent stack: remove the plugin, since Context Mode deliberately keeps data local and has no cloud processing path for your code.
- ↗To full source-code or prompt monitoring: move to a tool built for that, because the Platform forwards only structural metadata and never source code.
- ↗To a standalone AI observability platform: you would take on a new install on every machine, which Context Mode avoids by activating a layer already present.

Featured Head-to-Head Comparisons
Context Mode vs Spider Cloud
Context Mode is your pick if you're an AI-assisted developer drowning in token costs and want privacy-first context optimization. Spider Cloud wins if you need real-time web data for AI agents or RAG pipelines. They solve different problems: one trims LLM context, the other feeds it with external data. Buy both if your stack needs both.
Context Mode vs Temporal Ai
Temporal and Context Mode solve completely different problems. Temporal is a heavy-duty orchestration platform for building crash-proof AI agents and workflows, while Context Mode is a lightweight context-saver for coding agents. If your pain is agent reliability and cross-service orchestration, choose Temporal. If your pain is token costs from large tool outputs in coding assistants, choose Context Mode. They are complementary, not competitive.
Context Mode vs Voyage Ai
If you're building enterprise RAG on finance or legal documents, Voyage AI's domain-specialized embeddings and rerankers are unmatched. For developers using AI coding agents, Context Mode's free plugin slashes token waste by 98%, saving serious costs without sacrificing privacy. They solve completely different halves of the context problem — choose based on your workflow, not overlap.
