Local MCP server: five tools to store, retrieve, and retire project decisions. SQLite by default.

Krusch Context MCP gives AI coding agents (Cursor, Claude Code, Windsurf, Antigravity) persistent working memory across sessions. It captures architectural decisions, invariants, lessons, and bug diagnoses, warns on near-duplicate memories, maintains temporal lineage when facts are superseded or invalidated, and audits diffs against active constraints.
🚫 What This Is Not
- Not a codebase AST or Git indexer: Code symbol search, call graphs, and Git DAG traversal belong in
krusch-gitor your IDE's native search. - Not a 61-tool cafeteria: Collapsed to strictly 5 canonical verbs (~350 prompt tokens) for boring reliability.
- Not a cloud SaaS platform: Runs 100% locally on your machine with zero external cloud dependencies.
- Not a monolithic domain suite: Legal compliance (
krusch-law), document ingestion (krusch-nexus), and contract graphs (krusch-biz) live in separate companion repositories.
⚡ 30-Second Quickstart
Requires Node.js >= 22.0.0. Run once inside your project repository:
npx krusch-context-mcp init
This command will:
- Validate Node >= 22.0.0 and initialize
.agent/context.dbvianode:sqlite. - Clear stale MCP tool schemas from local IDE caches.
- Create your project
.envwith sensible defaults. - Seed initial project context and run a diagnostic health check.
- Print copy-paste JSON configurations for Cursor, Claude Code, and Claude Desktop.
🛠️ The 5-Verb Agent Loop
Krusch Context MCP exposes strictly 5 canonical verbs designed to fit into standard coding workflows:
| Verb | Short Alias | Purpose |
|---|---|---|
krusch_context_retrieve |
retrieve |
Pulls active memories, steering rules, and project state briefings within a strict limit_tokens budget. Returns citations. |
krusch_context_remember |
remember |
Writes episodic facts and steering nuggets. Detects near-duplicates (similarity >= 0.85) and proposes revise(action: 'supersede') without blocking contrasting rules. |
krusch_context_revise |
revise |
Updates stale knowledge (supersede with lineage tracking) or revokes obsolete rules (invalidate with mandatory reason). |
krusch_context_nudge |
nudge |
Pre-commit auditor that checks proposed diffs against active project invariants (max 1–3 findings). Trigger defaults to pre_commit or manual; rejects every_turn. |
krusch_context_health |
health |
Reports storage mode, memory counts by closed taxonomy, and 30-day TTL decay review. |
