Your security boundary fits: No auth required (Free / Open Source).
Find where your notes disagree — contradiction detection for markdown vaults.
Persistent, local-first AI memory: a semantic knowledge graph of plain Markdown files that humans and LLMs both read and write. Works with any MCP client, with optional cloud sync and team workspaces.
Scan the vault for note pairs with high concept overlap but conflicting numerical or qualitative claims. Returns all detected conflicts with the specific issues flagged.
check_pair
Run the full contradiction check between two specific notes (by path or filename stem). Returns the detailed conflict analysis — shared concepts, quantitative conflicts, negation conflicts.
extract_claims
Pull all quantitative claims (numbers with units) and negation patterns from a single note. Useful as input to your own verification pipeline.
generate_reconciliation_prompt
For 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.
Basic Memory Tools (15)
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
