Full-text search spaceflight news articles aggregated from dozens of sources (Spaceflight Now, NASASpaceflight, NASA, SpaceX, Blue Origin, ESA, and more). Filter by source, publish date, and featured status. Newest first. Keyless.
AI agents call search_articles to retrieve information from Spaceflight News MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
limit | number | — | Max articles to return (default 10, max 25). |
search | string | — | Full-text query, e.g. "starship", "artemis", "mars sample return". Optional — omit to list recent articles. |
news_site | string | — | Filter to a single source name, e.g. "Spaceflight Now", "NASASpaceflight". Use list_sources to discover names. |
featured_only | boolean | — | If true, return only editorially featured articles. |
published_after | string | — | Only articles published on/after this ISO date or datetime, e.g. "2026-01-01" or "2026-01-01T00:00:00Z". |

Attacks that exploit this kind of access
Full-text search spaceflight news articles aggregated from dozens of sources (Spaceflight Now, NASASpaceflight, NASA, SpaceX, Blue Origin, ESA, and more). Filter by source, publish date, and featured status. Newest first. Keyless. It is categorised as a Read tool in the Spaceflight News MCP MCP Server, which means it retrieves data without modifying state.
search_articles accepts 5 parameters: limit, search, news_site, featured_only, published_after. The full parameter table on this page comes from the server's own tool schema.
Register the Spaceflight News MCP server in PolicyLayer and add a rule for search_articles: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Spaceflight News MCP. Nothing to install.
search_articles is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the search_articles rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for search_articles. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
search_articles is provided by the Spaceflight News MCP server (pipeworx-io/mcp-spaceflight-news). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
