About
LSP call graph for coding agents: a symbol's callers, callees, tests and live files in one call.
Security Report
Rarefaction is a local stdio MCP server that wraps language servers to produce LSP call graphs; the code shown reads project files, spawns the configured language server binaries, and makes no outbound network calls by its own design. The main observations are the shell-free but configurable child process spawning from .rarefaction.json-provided commands and env overrides, which are expected for this tool category, plus minor code quality notes; no data exfiltration or malicious patterns were found in the reviewed files. Supply chain analysis found 1 known vulnerability in dependencies (0 critical, 1 high severity). Package verification found 1 issue.
