MCP Tool Search Budget Simulator

What This Tool Does

MCP Tool Search Budget Simulator is built for deterministic developer and agent workflows.

Compare full tool-schema injection versus search-first retrieval to model context cost, token pressure, and safe operating budgets before deployment.

How to Use MCP Tool Search Budget Simulator

  1. 1

    Provide workload sizing inputs

    Enter context window size, total tool count, average schema token size, query overhead, and retrieved tool count in JSON format.

  2. 2

    Run simulation for both injection strategies

    Execute Run Simulation to compute full injection and search-first token footprints side by side.

  3. 3

    Inspect savings and overflow status

    Review savings percentage, utilization, and overflow indicators to decide whether your current settings are safe for production traffic.

  4. 4

    Tune retrieved tools for safe headroom

    Use the recommendation output to adjust retrieval depth and re-run until you maintain acceptable context-window margin.

Frequently Asked Questions

What is MCP Tool Search Budget Simulator?
MCP Tool Search Budget Simulator estimates context-window usage for two strategies: full tool-schema injection and search-first retrieval. It helps teams choose safer token budgets before production rollout.
Which inputs are required?
Provide context window size, total tool count, average schema token size, retrieval overhead, and retrieved tool count. The simulator then calculates utilization, savings, and overflow risk.
What does overflow status mean?
Overflow means the computed prompt payload exceeds your configured context window for at least one strategy. Reduce tool count, schema size, or retrieved tools to restore safe headroom.
Does MCP Tool Search Budget Simulator store or send my data?
No. All calculations run locally in the browser and your planning inputs remain private.
