Convert your SOAP or REST API to an MCP server in 60 seconds

Repo: github.com/bvenkata/legacy2mcp

Letting an AI agent call a legacy system is risky. One wrong call to something like DeleteRecord and you have a problem.

legacy2mcp turns a SOAP/WSDL service, REST API or database into an MCP server, and it is safe by default:

Read-only by default. Write-like operations stay hidden until you opt in.
Schema-validated. Every call is checked before it reaches your backend.
Audit-logged. One JSON line per call.
Try it in 60 seconds
bash
pip install legacy2mcp
legacy2mcp init --rest-url https://petstore.swagger.io
legacy2mcp inspect --config config.yaml

For SOAP, use legacy2mcp init --wsdl-url instead.

inspect prints every MCP tool it generated. When it looks right, connect it to Claude Desktop or any MCP client:

json
{
"mcpServers": {
"legacy2mcp": {
"command": "uvx",
"args": ["legacy2mcp", "run", "--config", "/absolute/path/to/config.yaml"]
}
}
}
Known limits

The SOAP write filter is a name heuristic, so use include_operations for anything important. The MCP server has no auth yet, so don't expose it to untrusted callers.

Try it on your own system and tell me what breaks.
