t4ea-mcp 0.1.0

Teamcenter Gateway (T4EA) API Reference MCP Server

t4ea-mcp

MCP server that provides Teamcenter Gateway for Enterprise Applications (T4EA) API documentation to AI assistants. It enables AI coding tools like Claude, Cursor, and Windsurf to look up ITK functions, validate Tcl scripts, and navigate T4EA documentation accurately.

Why

AI assistants frequently hallucinate function names and parameters when writing Teamcenter/T4EA code. This MCP server gives them access to the actual API reference, a function allowlist, and a script linter — drastically reducing errors in generated Tcl/ITK code.

Installation

From PyPI

pip install t4ea-mcp

From source

git clone https://github.com/aldokruger/teamcenter-gateway-mcp.git
cd teamcenter-gateway-mcp
uv sync

Requirements: Python 3.10+

Quick Start

Run locally (stdio)

# Installed from PyPI
t4ea-mcp

# From source
uv run python -m t4ea_mcp

Run as HTTP server

t4ea-mcp --http --port 8000

Use the hosted version

A public instance is available at:

https://t4ea-mcp.fly.dev/mcp

Connecting to Your AI Client

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "t4ea": {
      "command": "t4ea-mcp"
    }
  }
}

Or use the remote server:

{
  "mcpServers": {
    "t4ea": {
      "url": "https://t4ea-mcp.fly.dev/mcp"
    }
  }
}

Claude Code

claude mcp add t4ea -- t4ea-mcp

Or remote:

claude mcp add t4ea --transport http https://t4ea-mcp.fly.dev/mcp

Cursor / Windsurf / VS Code

Add to your MCP settings (.cursor/mcp.json, etc.):

{
  "mcpServers": {
    "t4ea": {
      "command": "t4ea-mcp"
    }
  }
}

Tools

The server provides 9 tools:

Tool	Purpose
resolve_topic	Start here — routes natural language queries to the right docs
search_docs	Grep for exact strings across all documentation
get_doc	Read a specific documentation file (supports pagination)
get_section	Extract a section by markdown header
list_docs	List all available documentation files
get_functions	List valid T4EA/ITK functions by group
validate_function	Check if a function name exists in the allowlist
get_manifest	Get the LLM routing guide
lint_script	Lint Tcl/ITK scripts for errors and style issues

Recommended Workflow

1. resolve_topic("create item revision") — find relevant docs
2. get_functions("ITEM") — list valid ITEM functions
3. get_doc("modules/itk/item.md") — read the full reference
4. validate_function("ITEM_create_item") — verify before using
5. lint_script(your_code) — validate the generated script

Linter Rules

The lint_script tool checks for:

Rule	Severity	Description
E001	Error	Missing package require for used namespaces
E002	Error	Deprecated function usage
E004	Error	Removed/unsupported function usage
E005	Error	Function not found in the T4EA allowlist (likely hallucinated)
W001	Warning	Missing ITK_ok check after ITK calls
W002	Warning	Missing ITK::isITK_ok guard pattern

Documentation Coverage

The server bundles comprehensive T4EA reference documentation:

• 42 ITK modules — AOM, BOM, ITEM, EPM, AM, POM, and more
• 23 utility modules — base64, SQL, SOAP, HTML/XML, encryption, etc.
• 100+ namespaces — pipeline, configuration, OAuth2, monitoring, pl4x, and more
• 7 class references — PipelineStep, StepParameter types, Function
• Function allowlist — JSON index of all valid T4EA/ITK function names
