When to pick vikasny30/aletheia-mcp
Deterministic (no-LLM) pre-execution filter for agent tool calls. Pattern-matches known scope-creep (out-of-mandate writes, credential-file reads, SSRF, destructive shell/SQL) and prompt-injection vectors and blocks them in ~25 µs. Runs as standalone guard tools or a fail-closed transparent proxy in front of any downstream MCP server. Signatures from the Aletheia research paper; a first-line pre-filter, not a sandbox.
