Mcp Contradiction Check
Runs static analysis on your markdown vault to catch notes that cite conflicting numbers or make opposing claims about the same concepts. The find_contradictions tool scans for pairs with high semantic overlap but disagreeing quantitative values or negation patterns, while check_pair lets you audit two specific files. Free tier covers detection, Pro tier adds extract_claims for pulling structured assertions from individual notes and generate_reconciliation_prompt to build LLM inputs that preserve full context for dispute resolution. Built to complement hebbian-vault's retrieval weighting so you don't reinforce contradictory knowledge. Useful if you maintain a growing knowledge base where stale or conflicting information creeps in across hundreds of notes and you need automated flagging before the inconsistencies propagate.

extract_claimsPull all quantitative claims (numbers with units) and negation patterns from a single note. Useful as input to your own verification pipeline.

generate_reconciliation_promptFor a detected contradiction, produce a structured prompt you can feed to an LLM to reason through the conflict and suggest a resolution. Preserves the exact claims + shared concepts + both notes' context windows.

mcp-contradiction-check
Find where your notes disagree — contradiction detection for markdown vaults.
Find pairs of notes in your markdown knowledge base that have high concept overlap but disagree — quantitative conflicts (different numbers with the same unit on the same concept) and negation conflicts (one note claims "X is not Y", another claims "X is Y"). Prevents knowledge corruption by surfacing disputes before they propagate. Designed to pair with hebbian-vault's usage-weighted retrieval to flag notes that shouldn't be strengthened yet.
