README
Sverklo
Sverklo (Russian: сверкло, SVERK-lo) — archaic past tense of "сверкнуть," to flash or gleam. Code intelligence that illuminates your repo so your AI assistant stops guessing.
MIT Licensed — the only fully open-source code intelligence MCP. Free for commercial use, no restrictions. Compare with alternatives →
Stop re-explaining your codebase to your AI.
Sverklo is a local-first code intelligence MCP server that gives Claude Code, Cursor, Windsurf, VS Code, JetBrains, and Google Antigravity the same mental model of your repo that a senior engineer has. Hybrid semantic search, symbol-level blast-radius analysis, diff-aware PR review, and memory pinned to git state — running entirely on your laptop.
The problem
Your AI agent edits UserService.validate(). It doesn't know that 47 other functions call it. Breaking changes ship. Tests pass because they mock the dependency.
Sverklo gives your agent the dependency graph, the blast radius, and the risk score — before it writes a single line.
| 20 tools your agent actually uses | < 2 s to index a 1,700-file monorepo | 0 bytes of your code leave your machine |
npm install -g sverklo
cd your-project && sverklo init
sverklo init auto-detects your installed AI coding agents, writes the right MCP config files, appends sverklo instructions to your CLAUDE.md, and runs sverklo doctor to verify the setup. MIT licensed. Zero config. No API keys.

First 5 minutes: see
FIRST_RUN.mdfor three scripted prompts that demonstrate the tools sverklo adds that grep can't replace.
Grep vs Sverklo — the same question, side by side
Every one of these is a query a real engineer asked a real AI assistant last week. Grep gives you lines. Sverklo gives you a ranked answer.
| The question | With Grep | With Sverklo |
|---|---|---|
| "Where is auth handled in this repo?" | grep -r 'auth' . → 847 matches across tests, comments, unrelated vars, and one 2021 TODO | sverklo_search "authentication flow" → top 5 files ranked by PageRank: middleware, JWT verifier, session store, login route, logout route |
"Can I safely rename BillingAccount.charge?" | grep '\.charge(' → 312 matches polluted by recharge, discharge, Battery.charge fixtures | sverklo_impact BillingAccount.charge → 14 real callers, depth-ranked, with file paths and line numbers |
| "Is this helper actually used anywhere?" | grep -r 'parseFoo' . → 4 matches in 3 files. Are any real, or just string mentions? Read each one. | sverklo_refs parseFoo → 0 real callers. Zero. Walk the symbol graph, not the text. Delete the function. |
| "What's load-bearing in this codebase?" | find . -name '*.ts' | xargs wc -l | sort |
