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

Description and use

legacy2mcp converts a legacy SOAP or REST API into a safe MCP server in 60 seconds, providing read‑only access, schema validation, and audit logging.

Problem

Legacy systems expose risky operations; a single wrong call can cause serious issues.

Outcome

The legacy2mcp tool transforms a legacy SOAP or REST API into a safe MCP server within 60 seconds, providing read‑only access, schema validation, and audit logging.

Workflow

• Install legacy2mcp via pip
• Initialize the MCP server with the legacy endpoint using legacy2mcp init --rest-url or --wsdl-url
• Run legacy2mcp inspect to generate MCP tools and review the config
• Connect an MCP client (e.g., Claude Desktop) to the generated MCP server via the provided JSON configuration

Evidence

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

Source

Read‑only by default. Write‑like operations stay hidden until you opt in.

Source

Schema‑validated. Every call is checked before it reaches your backend.

Source

Audit‑logged. One JSON line per call.
