OpenRouter MCP Multimodal Server v3.0.0 — the most comprehensive multimodal MCP server available. 11 tools: chat_completion, analyze_image, analyze_audio, analyze_video, generate_image, generate_audio, generate_video, get_video_status, search_models, get_model_info, validate_model. Security highlights: • IPv4 + IPv6 SSRF blocklist (covers mapped, compat, multicast, 6to4, Teredo, ORCHID, ULA, link-local, documentation ranges) • Path-sandboxed disk writes (save_path validated against OPENROUTER_OUTPUT_DIR before any API call) • No credentials in deeplinks or logs • Bounded URL fetches with Content-Length short-circuit, redirect cap, and per-hop re-validation • Retry-After-aware backoff with jitter (no thundering herd) • Closed error taxonomy (_meta.code) — no internal paths or stack traces leak to clients • MCP 2025 tool annotations (readOnlyHint, destructiveHint, idempotentHint) on every tool • Process safety: uncaught exceptions exit cleanly (no zombie servers) 163 unit tests, 16 live E2E scenarios against real OpenRouter API.
