Epoch MCP server

Epoch -- Time Estimation MCP Server

Epoch is a time estimation MCP server that helps engineering leads, agents, and planners who need calibrated duration estimates produce PERT/reference-class estimates and record actuals.

TL;DR: Epoch — time estimation MCP server. Best for engineering leads, agents, and planners who need calibrated duration estimates.

Epoch helps AI agents understand time.

AI can write code, analyze data, and build apps -- but it can't tell you how long something will take, what it'll cost, or whether a deadline is realistic. Epoch fixes that.

Show Me

You: "How long will a 15,000 line project take with a small team?"

Claude (using Epoch):
  COCOMO II nominal: 100 person-months (traditional team)
  AI-adjusted: 9 person-months (LLM-assisted workflow)
  Schedule risk: medium (MAPE 15%, based on 28 historical features)
  Cost estimate (Claude Sonnet): ~$340 in API tokens

You: "How many working days between now and launch?"

Claude (using Epoch):
  Start: May 1, 2026
  End: July 15, 2026
  Business days: 54
  Weekend days: 16
  Holidays: 1 (Independence Day)
  Total calendar days: 75

You: "Which AI model should we use for a 50k-token job?"

Claude (using Epoch):
  gemini-2.0-flash:  $0.02 -- fast, budget-friendly
  gpt-4o-mini:       $0.02 -- fast, budget-friendly
  gemini-2.5-pro:    $0.37 -- standard, high quality
  claude-sonnet-5:    $0.57 -- standard, high quality
  Recommendation: gemini-2.0-flash for cost, claude-sonnet-5 for quality

Why Epoch?

Every AI agent hallucinates timelines. "This should take about 2 hours" becomes 2 days. Epoch gives AI grounded, data-driven estimates instead of guesses. It packages established estimation methods (PERT, COCOMO II, Monte Carlo, reference class forecasting) into 26 tools any AI can call -- so your assistant stops guessing and starts calculating.

Works out of the box. Epoch ships with a bundled reference database: task-type correction factors and scope baselines from the maintainer's recorded estimate-vs-actual history plus curated public research, and tool-usage/latency telemetry samples (117,791 across the bundled canary-test and session benchmarks) that keep the token-time bridge grounded. You get reasonable estimates from day one — no data collection or account setup required. If you choose to record your actuals, Epoch's self-improvement engine learns your patterns and gets even more precise over time.

What is MCP?

MCP (Model Context Protocol) is how AI assistants like Claude connect to external tools. Think of it like a plugin system -- you add Epoch with one command, and suddenly your AI assistant can estimate timelines, calculate business days, compare model costs, and predict whether your project will finish on time.

Quick Start

30-second setup -- works in Claude Code, Cursor, VS Code, and Windsurf:

claude mcp add epoch -- npx @kyanitelabs/epoch

That's it. Your AI assistant now has 26 time estimation tools.

Or add it to your project's .mcp.json:
