Halo Surface Signal MCP Server for Threat Advisories
Bring published Halo Surface Signal and H/A/L/O threat advisory context into Cursor, Claude-compatible MCP clients, and security workflows with one login-generated API key.
Operationalize the signal where teams already work
The Halo Surface Signal MCP server exposes published threat advisories through standard MCP tool calls, so AI IDEs and security assistants can answer questions with the same public Signal and H/A/L/O advisory structure readers see on Halo Threat Intelligence.
The public website helps teams evaluate the signal. The authenticated MCP setup console turns that interest into a key, endpoint, and first query without requiring a custom API learning curve.
Use it with MCP
Log in once, generate an API key, and configure your MCP client with the Halo endpoint and Authorization bearer key. MCP requests do not require an active browser session after key creation.
The v1 tool set is intentionally narrow: list published Halo threat advisories, get one threat advisory by CVE ID, and search published threat advisory summaries for read-only workflow context.
What the feed includes
Each threat advisory centers Halo Surface Signal, the 1-5 public exposure lens for vulnerability triage. Full threat advisory lookups include the H/A/L/O sections: Horizon Alert, Attack Path, Live Threat, and Operational Fix.
Responses include a canonical advisory URL, concise summary, and supporting CVE facts where those facts are already part of the published threat advisory contract.
Where it fits
Use it for vulnerability prioritization, SOC enrichment, attack-surface triage, AI IDE context, internal tickets, and security assistant grounding.
The server is read-only. It does not expose admin actions, drafts, batch jobs, generation workflows, raw scoring internals, or customer data.
Start from live advisories
Browse public CVE advisories to understand the Signal in context, then sign in to generate a key when you are ready to connect your own client.
More read-only Surface Signal integrations can be added later without changing the core key model.
