Frequently Asked Questions

What is Serena?

A fully-featured coding agent that relies on symbolic code operations by using language servers.

What tools does Serena provide?

Serena provides 39 tools including find_symbol, find_referencing_symbols, get_symbols_overview, insert_after_symbol. Each tool can be called by AI agents to perform specific operations.

Is Serena safe to use?

We cannot tell you that, and nobody scanning at this scale can. What we did in March 2026 was shallow-clone Serena 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. At least one matched — the specific finding is in the scan report on this page. 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.
