Tokencast
Estimate token and dollar cost before you run long agent workflows, then tighten forecasts with calibration over time.
Overview
tokencast is a MCP server for the Operate phase that estimates LLM agent workflow cost before execution and improves forecasts via calibration learning.
What is this MCP server?
- Pre-execution cost estimation before agent workflows run
- Calibration learning to improve estimates from past runs
- Stdio MCP server distributed via PyPI package tokencast
- Fits budget checks before expensive multi-step agent chains
- Version 0.1.1 MCP registry entry for agent clients
- Server version 0.1.1
- PyPI identifier tokencast with stdio transport
- Advertised features: pre-execution cost estimation and calibration learning
Community signal: 1 GitHub stars.
What problem does it solve?
You only discover how expensive an agent workflow was after it finishes, which makes solo-builder API budgets easy to blow on one unscoped run.
Who is it for?
Indie builders running frequent multi-step agent workflows who want a MCP-side cost preview before triggering long jobs.
Skip if: Builders who only run rare single-shot prompts or who already have a full observability platform with enforced spend policies and no need for MCP estimates.
What do I get? / Deliverables
After install, you can query pre-execution cost estimates and benefit from calibration that tightens future forecasts before you launch agent jobs.
- Pre-execution cost estimates exposed as MCP tools
- Calibration-informed forecasts for repeat agent workflows
- Stdio MCP registration via PyPI package tokencast 0.1.1

How it compares
LLM cost-estimation MCP, not a code search or task-management server.
Common Questions / FAQ
Who is Tokencast for?
Solo developers and small teams using MCP agents who need upfront token or cost estimates before expensive autonomous workflows.
When should I use Tokencast?
Use it in Operate when you are about to run repeatable agent pipelines and want a forecast plus improving calibration instead of surprise bills.
How do I add Tokencast to my agent?
Add the PyPI stdio MCP server Tokencast (version 0.1.1) to your Claude Code or Cursor MCP configuration and call its estimation tools before executing workflows.
