Ignition MCP vs MoldSim MCP Server
A side-by-side look at the Ignition MCP and MoldSim MCP Server MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Ignition MCP for industrial & iot work as a local process; choose MoldSim MCP Server for industrial & iot as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Ignition MCP when
- You need dedicated capabilities in the Industrial & IoT domain.
- You prefer a local stdio subprocess transport.
- You have the keys it needs:
IGNITION_URL, IGNITION_API_TOKEN, IGNITION_BRIDGE_SECRET, IGNITION_ALLOW_WRITES, IGNITION_TLS_VERIFY, IGNITION_TIMEOUT_S, IGNITION_TAG_WRITE_ALLOWLIST.
Choose MoldSim MCP Server when
- You need dedicated capabilities in the Industrial & IoT domain.
- You prefer a local stdio subprocess transport.
- You want tools like
query_simulation_knowledge, get_material_properties, validate_process_parameters.

Frequently asked questions
Ignition MCP is categorized under Industrial & IoT and uses a local stdio subprocess. MoldSim MCP Server belongs to Industrial & IoT and uses a local stdio subprocess. Pick Ignition MCP for industrial & iot work and MoldSim MCP Server for industrial & iot.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Ignition MCP has no declared pricing — check the project's own site. MoldSim MCP Server has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add ignition-mcp and moldsim-mcp-server as separate keys in the same mcpServers object, and your assistant will call tools from either one.
