Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "jcgeagentinterface-jl": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "ghcr.io/equicirco/jcge-agentinterface-mcp:0.3.1"
      ]
    }
  }
}

Run this in your terminal

claude mcp add jcgeagentinterface-jl -- docker run -i --rm ghcr.io/equicirco/jcge-agentinterface-mcp:0.3.1

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "jcgeagentinterface-jl": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "ghcr.io/equicirco/jcge-agentinterface-mcp:0.3.1"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "jcgeagentinterface-jl": {
      "type": "stdio",
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "ghcr.io/equicirco/jcge-agentinterface-mcp:0.3.1"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is JCGE Agent Interface safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.3.1) reached the registry last month.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Docker on your computer.

What can I use instead?

JCGEAgentInterface

What is a CGE?

A Computable General Equilibrium (CGE) model is a quantitative economic model that represents an economy as interconnected markets for goods and services, factors of production, institutions, and the rest of the world. It is calibrated with data (typically a Social Accounting Matrix) and solved numerically as a system of nonlinear equations until equilibrium conditions (zero-profit, market-clearing, and income-balance) hold within tolerance.

What is JCGE?

JCGE is a block-based CGE modeling and execution framework in Julia. It defines a shared RunSpec structure and reusable blocks so models can be assembled, validated, solved, and compared consistently across packages.

What is this package?

MCP-compatible interface layer for agents that need to discover, load, solve, validate, and inspect

JCGE models. It exposes a small action API and a standard MCP stdio server over the same functionality.

The agent surface is intentionally focused on:

discovering installed JCGE packages and available functionality,
listing and describing reusable JCGEBlocks components,
guiding users through CGE model development with JCGE blocks,
guiding formulation choices such as equality systems, inequalities, MCP/complementarity, and optimization-style representations,
guiding source-data preparation with released JCGEImportData adapters while retaining model-owned SAM construction choices,
guiding calibration with the currently available JCGECalibrate loaders, SAM helpers, labeled containers, and parameter workflows,
guiding solver choice and reporting from generated equations,
listing released JCGEExamples reference model modules,
solving registered RunSpec models,
validating solved contexts,
rendering implemented equations, blocks, and symbols through JCGEOutput,
reporting or applying updates to released JCGE packages in the active Julia environment.

The package services are grouped in the documentation as discovery, modeling guidance, model interaction, reporting, environment maintenance, and MCP runtime services. See docs/src/services.md for the full service contract and current limits.

MCP server

The standard MCP transport is:

using JCGEAgentInterface

serve(transport=:mcp_stdio)

Minimal local MCP client configuration:

"mcpServers": { "jcge": { "command": "julia", "args": [ "--project=/path/to/JCGEAgentInterface.jl", "-e", "using JCGEAgentInterface; serve(transport=:mcp_stdio)" ] } } }

The MCP tools use the jcge_ prefix:

jcge_capabilities
jcge_list_blocks
jcge_describe_block
jcge_modeling_guide
jcge_formulation_guide
jcge_solver_guide
jcge_import_data_guide
jcge_calibration_guide
jcge_reporting_guide
jcge_list_examples
jcge_package_status
jcge_update_packages
jcge_list_models
jcge_load_model
jcge_solve
jcge_validate_model
jcge_render_model
jcge_export_results

The original custom JSON action protocol remains available:

serve() reads JSON requests from stdin and writes JSON responses to stdout.

Docker and MCP Registry

OCI-oriented MCP registry metadata is declared in server.json.

Future version tags matching v*.*.* trigger .github/workflows/publish-mcp.yml, which:

verifies the tag version matches Project.toml,
builds the MCP Docker image,
pushes it to GitHub Container Registry as ghcr.io/equicirco/jcge-agentinterface-mcp: ,
updates server.json for that release,
publishes the metadata to the official MCP Registry through GitHub OIDC.

The Docker image includes the MCP ownership label required by the MCP Registry:

LABEL io.modelcontextprotocol.server.name="io.github.equicirco/JCGEAgentInterface.jl"

No release, tag, image publication, or registry publication is performed by editing this repository.
