Frequently Asked Questions

What is Cicada?

Code Intelligence for Elixir: module search, function tracking, and PR attribution through tree-sitter AST parsing

Is Cicada safe to use?

We cannot tell you that, and nobody scanning at this scale can. What we did in March 2026 was shallow-clone Cicada and run five keyword searches over its source: auth identifiers, CORS configuration, rate-limit identifiers, the dependency manifest against a hardcoded list of 18 known-vulnerable packages, and unguarded eval/exec calls. None of them matched. A text search cannot follow a variable, judge intent, or tell you what a server does once it is running, so "nothing matched" is not "safe". What the scan does and does not cover is written out at /mcp/security.

What are alternatives to Cicada?

Similar MCP servers include Serena, MCP Run Python, DesktopCommanderMCP. Each serves a similar purpose but may differ in features, language, and compatibility.
