An open-source MCP council checks every quote word-for-word and abstains when unsure
ilyautov · reddit · 2026-07-28
An open-source MCP server and Claude Code skill designed to prevent hallucinated quotes and citations.
- The builder was motivated by two failure modes: models sound confident when they are wrong, and they invent quotes to sound more convincing.
- The system uses a “council” of advisors grounded in public-domain corpora, with retrieval-based evidence rather than roleplay.
- It supports a simple local tier with lexical char-ngram retrieval and exact-match citation gating, and a fuller tier using semantic retrieval with bge-m3 on Ollama.
- Every word-for-word quote is checked against the source corpus; if grounding is missing, the system abstains instead of fabricating an answer.
- The author says the repo is open source and invites critique on the retrieval/abstention design.
