Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Curated set · 3 capabilities

We ship only the actions that matter.

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through Claude Context Tracker.

  1. 01

    Apply pruning recommendation

    This capability checks if a suggested way to clear out context actually makes sense for your current session.

  2. 02

    Track consumption

    This capability updates the current token count by recording the character length of new information added to the chat.

  3. 03

    Get budget configuration

    This capability pulls your current token limits and the specific thresholds set for your session.

Real work

What teams actually run

01

Large File Analysis

The agent tracks how much of the window is used when reading massive datasets.

02

Long-Running Agents

An agent monitors its own budget during multi-step workflows to avoid crashing.

03

Capability-Heavy Workflows

Managing the cumulative token cost of frequent capability outputs and function calls.

04

Context Optimization

Deciding when to prune specific parts of a conversation to free up space.

One connector, every AI

Claude Context Tracker works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Who it's for

Built for the work Claude Context Tracker owners hand off.

This is for anyone running long, complex sessions where context management is a bottleneck.

  • 01

    AI Developers

    Building agents that need to stay within strict token limits during long tasks.

  • 02

    Data Analysts

    Processing large files that risk saturating the context window quickly.

  • 03

    Prompt Engineers

    Testing how different system prompts and capability outputs impact total token spend.

FAQ

Questions Claude Context Tracker owners ask.

  • 01

    How does this MCP calculate tokens?

    It uses deterministic character-based estimation to track usage for system prompts, files, and history.

  • 02

    Will this work with Claude?

    Yes, it is designed specifically to monitor and manage the Claude context window.

  • 03

    Can I set my own token limits?

    Yes, you can use the budget configuration capabilities to manage active limits and thresholds.

  • 04

    What happens when the context window is full?

    The MCP helps the agent identify when it is approaching limits so it can prune data before performance drops.

  • 05

    Does this work in Cursor or Windsurf?

    It works with any MCP-compatible client, including Cursor and Windsurf.

  • 06

    How does this capability estimate tokens?

    It uses a deterministic character counting method where code is estimated at 3.5 characters per token and prose at 4 characters per token.

  • 07

    What happens when I reach the critical threshold?

    When the critical threshold is reached, the capability returns a mandatory_action which specifies exactly how many tokens must be freed to continue effectively.

  • 08

    Can I customize my token budgets?

    Yes, you can use get_budget_configuration to retrieve the active limits and thresholds currently applied to your session.
