Knowledge graph for token-efficient code reviews -- semantic search and call-graph resolution across your codebase.
n24q02m/crg is an MCP server distributed on github, maintained by n24q02m, tracked here since September 2026. It has shipped 110 releases and exposes 25 tools. Tools include build, cache_clear, diff, embed, export, impact, and 19 more. Its composite risk grade is B — an inferred review prompt computed from observed signals, not a verdict.
Reading the source raised 2 review prompts — dangerous code and exfiltration combo — each a pattern worth a human look rather than a finding of fault.
full security breakdown →-
buildFull or incremental graph build. Set full_rebuild=true to re-parse all files; pass roots to federate extra repo directories into one graph. -
cache_clearRemove all computed embeddings. -
diffNodes added/removed/modified between two commit SHAs (from_sha, to_sha). -
embedCompute vector embeddings for semantic search. Dual-mode: local ONNX or cloud chain. -
exportExport the graph as graphml / json-ld / dot / cypher. Inline or to output_path. -
impactBlast radius of changed files. Auto-detects from git diff. Paginated with max_results. -
large_functionsFind functions/classes exceeding a line-count threshold. -
queryPredefined patterns: callers_of, callees_of, imports_of, importers_of, children_of, tests_for, inheritors_of, file_summary. -
renamed_in_diffSymbols whose callsite line shifted versus a base ref. -
reportRe-emit cached findings as JSON (format='json') or SARIF v2.1.0 (format='sarif'). -
rule_listList available rules for an engine. -
scanRun a security scan (engine='heuristic' default = 5 regex rules, or 'semgrep'). Findings persist on nodes.security_tags. -
searchSearch code entities by name/keyword or semantic similarity. -
setUpdate a runtime setting (key=log_level). -
setup_completeRe-resolve credentials from environment variables. -
setup_resetClear credentials and reset state. -
setup_skipSet local mode (skip relay permanently, use ONNX only). -
setup_startStart relay setup to configure API keys via browser (HTTP mode). -
setup_statusShow current credential state, providers configured, and setup URL. -
spot_checkRandom callsite snippets from the last callers_of/callees_of/inheritors_of/importers_of result.
