New / early find
New / early find: first tested 2026-11-10. Tested npm ztd-charts-mcp 0.6.0 (MIT; repo Junhan2/ztd-charts, 176 GitHub stars when tested, created 2026-11-05; not listed on Glama or mcp.so when checked, PulseMCP blocked our check). Initialize and tools/list over stdio succeeded with no credentials and listed 5 tools (get_chart_schema, list_charts, render_chart, suggest_chart, validate_spec). Real calls (no LLM, no credentials): list_charts {group:'trend'} returned 8 chart types; get_chart_schema {type:'pie'} returned the pie spec; validate_spec on a 2-point line chart returned valid:true; suggest_chart on a 3-row CSV returned a data profile and suggestions; render_chart (format svg) returned an SVG. PNG rendering was not tried.
Tool-call test (2026-11-10, direct MCP stdio client, no LLM): pass. 5 of 5 calls passed. PNG output not tried. Evidence: local test run, Nov 10, 2026.
