Official MCP server for the Geneva Forecasting Engine by RoadMap Technologies — statistical forecasting for AI agents

Geneva MCP

Time-Series Forecasting & Demand Planning for AI Agents
Powered by the Geneva Forecasting Engine — by RoadMap Technologies

---

Geneva MCP brings production-grade statistical forecasting directly into AI assistants and coding agents. Connect any MCP-compatible client to the Geneva Forecasting Engine and run rigorous time series forecasts through natural conversation — no code, no pipelines, no exports required.

"Forecast the next 12 months of this sales data with 95% prediction intervals."

The agent calls the Geneva Engine behind the scenes, receives a numerical analysis and a forecast chart, and delivers a complete, statistically grounded interpretation — all in a single conversation turn.

Why Geneva MCP?

Free to Get Started — No Credit Card Required

The Geneva API is free with 1,000 forecasts per month. Sign up at the Developer Portal, generate your API key, and start forecasting in minutes. No trial periods, no paywalls, no surprises.

Forecast in Claude Chat

With Geneva MCP connected, Claude becomes a full forecasting analyst. Paste your data directly into the conversation, ask a question in plain language, and Claude will forecast, analyze, and visualize the results — model selection, accuracy metrics, trend commentary, and a chart, all delivered in a single response.

Claude with Geneva MCP — describe your data, get a complete forecast with analysis and chart in one turn

---

Forecast from Excel with Claude Cowork

Claude Cowork users can forecast directly from spreadsheets. Drop your .xlsx or .csv file into the conversation, describe the column you want to forecast, and Geneva handles the rest — complete with prediction intervals and a chart. No data pipelines, no Python scripts, no manual exports.

From spreadsheet to forecast in one sentence.

Claude Cowork with Geneva MCP — attach an Excel or CSV file and forecast any column in plain language

Fast & Purpose-Built

Geneva is a dedicated forecasting engine, not a general-purpose language model. Forecasts return in milliseconds with structured output and a chart — every time, with consistent and reproducible results. Geneva returns both a full numerical analysis and a chart image ready for the agent to embed directly in the conversation.

Chart generated by Geneva MCP — historical data, forecast line, and confidence interval bands at your chosen level

Quick Start

Step 1 — Get Your Free API Key

Visit the Geneva Developer Portal to create a free account and generate your API key. The free tier includes 1,000 forecasts per month with no credit card required.

---

Step 2 — Configure Your Agent

Add the Geneva MCP server to your agent's configuration file. Replace gva_your_key_here with your API key.

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "geneva": {
      "command": "uvx",
      "args": ["geneva-mcp"],
      "env": {
        "GENEVA_API_URL": "https://api.roadmap-tech.com",
        "GENEVA_API_KEY": "gva_your_key_here"
      }
    }
  }
}

Restart Claude Desktop — the forecast tool will appear automatically in the tool list.

---

Claude Cowork

Follow the same configuration as Claude Desktop above. Once configured, you can attach an .xlsx or .csv file to the conversation and instruct Claude to forecast any column — Geneva will handle model selection, computation, and visualization automatically.

---

ChatGPT Desktop

1. Open ChatGPT Desktop → Settings → Developer Mode (requires Plus or Pro)
2. Add an MCP server with:
   • Command: uvx
   • Args: geneva-mcp
   • Environment variables:
     • GENEVA_API_URL = https://api.roadmap-tech.com
     • GENEVA_API_KEY = gva_your_key_here

---

Cursor

Add to .cursor/mcp.json in your project root or global settings:

{
  "mcpServers": {
    "geneva": {
      "command": "uvx",
      "args": ["geneva-mcp"],
      "env": {
        "GENEVA_API_URL": "https://api.roadmap-tech.com",
        "GENEVA_API_KEY": "gva_your_key_here"
      }
    }
  }
}

---

Windsurf

Add to ~/.windsurf/mcp.json:

{
  "mcpServers": {
    "geneva": {
      "command": "uvx",
      "args": ["geneva-mcp"],
      "env": {
        "GENEVA_API_URL": "https://api.roadmap-tech.com",
        "GENEVA_API_KEY": "gva_your_key_here"
      }
    }
  }
}

---

Step 3 — Start Forecasting

Ask your agent to forecast any time series in plain language:

"Here are my last 36 months of revenue: [120, 135, 128, ...]. Forecast the next 18 months with 95% confidence intervals."

The agent receives structured forecast data and an embedded chart visualization, then provides a complete analysis covering model selection rationale, accuracy metrics, trend direction, seasonal patterns, and prediction intervals.

                                                  └──────────────────────┘

The MCP server runs locally as a lightweight Python process. It communicates with the AI agent over stdio using the MCP protocol and calls the Geneva Forecasting Engine API over HTTPS. The server is fully stateless and produces no local side effects.

Tool Reference

forecast

Run a single time series forecast through the Geneva Forecasting Engine.

Note: Each tool call processes one time series. For batch forecasting across multiple series, use the Geneva Python SDK directly.

Parameter	Type	Required	Default	Description
data	list[float]	✅	—	Time series observations (3–10,000 data points)
horizon	int	—	auto	Number of future periods to forecast
wave_periods	list[int]	—	[12]	Seasonal cycle lengths (12=monthly, 4=quarterly, 52=weekly, 7=daily)
confidence_level	float	—	0.95	Prediction interval confidence level (0.0–1.0)
method	int	—	auto	Force a specific method (0–9). Omit to let the Expert System select automatically
seasonal_transform	int	—	0	Seasonal transform: 0=None, 1=Seasonal, 2=MPT
smoothing	bool	—	false	Enable median smoothing for noisy data
max_periods_factor	float	—	engine default	Fit window cap factor — increase for long series
holdout_ratio	float	—	engine default	Fraction of data reserved for model evaluation

Returns: A structured multimodal response containing:

• Text summary — Selected model name, accuracy metrics (MAD, MAPE, RMSE), forecast values with prediction intervals, in markdown format ready for agent interpretation
• Chart image — A forecast chart with historical data, forecast line, and shaded prediction interval bands

Forecasting Methods

The Geneva Expert System automatically evaluates all 10 methods and selects the best fit for your data. You can also specify a method manually using the method parameter.

ID	Method	Best For
0	Linear Regression	Steady linear growth or decline
1–5	Non-Linear Regression (5 curve types)	Exponential, s-curve, power trends
6	Simple Exponential Smoothing	Stable, level series
7	Double Exponential Smoothing (Holt)	Trending series without seasonality
8	Holt-Winters (Seasonal)	Trending + seasonal series
9	Croston (Intermittent Demand)	Sporadic, zero-inflated series

---

Troubleshooting

GENEVA_API_KEY environment variable is not set

The env block is missing from your agent's MCP configuration, or the API key value is empty. Add a valid key from the Geneva Developer Portal.

Server transport closed unexpectedly

The Python process crashed before the MCP handshake completed. Verify your installation by running the server manually:

GENEVA_API_KEY=your_key GENEVA_API_URL=https://api.roadmap-tech.com geneva-mcp

Chart rendering issues

The server uses a headless matplotlib backend (Agg) that requires no display server. If chart generation fails, reinstall matplotlib:

pip install matplotlib --force-reinstall
