heim — local, on-box LLM platform: build a model library, then run, chat, and serve it with MCP tools. Ships a DHIS2 assistant Chrome side panel. Source-available, proprietary.
winterop-com/heim is an MCP server distributed on github, maintained by winterop-com, tracked here since July 2026. It has shipped 3 releases and exposes 70 tools. Tools include add_to_date, base64_decode, base64_encode, calc, char_count, convert_time, and 64 more. Its composite risk grade is C — an inferred review prompt computed from observed signals, not a verdict.
Reading the source raised 2 review prompts — exfiltration combo and toxic flow (lethal trifecta) — each a pattern worth a human look rather than a finding of fault.
