ai.helixar由 helixar.ai 发布官方发布者v0.0.1更新于 Oct 24, 2026
Security tools for AI agents: scan MCP servers, validate HDP delegation chains, audit releases.
远程安全服务器，让助手扫描 MCP 服务器的风险并校验 HDP 代理委派链。
Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。
把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。
阅读 https://sourceweft.com/mcp/ai.helixar%2Fmcp/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。把它添加到你客户端的 mcpServers 配置中。

}Agentic-AI security tools for Claude, exposed as a remote MCP server.
Status: Live at
https://mcp.helixar.ai/mcp. Two tools available remotely (Streamable HTTP); a third runs locally over stdio. Public, no-auth in v1 — OAuth lands with Phase 8.
https://mcp.helixar.ai/mcphelixar_inspect_mcp and helixar_hdp_validate appear in the tool picker.mcp_servers)Add the server directly in a Messages API call (beta header mcp-client-2025-11-20):
The Workers deployment exposes two of three tools. helixar_releaseguard shells out to a Go binary via child_process and has no Workers equivalent — it remains stdio-only. For the full set, run locally:
Once the connector is added, paste either of these into a Claude chat. Both target the same intentionally-risky manifest in examples/risky-manifest.json and trip 7 of 8 quick-mode rules.
Inline JSON (works anywhere — no internet fetch from Claude's side):
URL (the same fixture, fetched by Sentinel through its SSRF guard):
Either prompt produces a CRIT-level finding (risk_score 100) flagging:
@modelcontextprotocol/sdk (official Anthropic)src/worker.ts), WebStandardStreamableHTTPServerTransport, statelesssrc/server.ts)api_key field in the tool's input arguments). OAuth 2.0 + Dynamic Client Registration is Phase 8.Per the implementation plan §6, internal detection methodology, Hunch Mode internals, sensor implementation, and exact thresholds are never exposed in this codebase. Public surface is rule IDs, severity buckets, public-safe detection categories, and remediation guidance only. The earlier helixar_triage_alert tool was revoked in v0.4.1 after review flagged that exposing kill-chain stage classifiers — even stripped — widened the public attack surface too far; helixar_releaseguard (wrapping the already-open-source Helixar-AI/ReleaseGuard) replaces it.

Scan an MCP server (URL or raw manifest JSON) against Helixar's Sentinel detection rules. Returns risk score, findings, and a Claude-generated security brief. Quick mode is free + authless (top 8 rules); deep mode runs all 26 rules with an api_key.
