⚙️ MCP Configuration (LM Studio)
Add to mcp.json of LM Studio:
{
"mcpServers": {
"TOOL4LM": {
"command": "node",
"args": ["--enable-source-maps", "C:/path/to/tool4lm/dist/server.js"],
"type": "mcp",
"env": {

📝 Example of usage flow
Web search with citations → web.search → web.fetch → web.read → summary + attach URL.\ Internal document → doc.find → doc.read summary + excerpt (with notes included path)\ Academic → sch.search → sch.get theo DOI/arXivId.\ Calculation → calc.eval with ^/pow(a,b) (or has been normalized **)
