# ripestat-announced-prefixes List all IP prefixes announced by an ASN over a time window. Agent View of the PolicyLayer registry record for `ripestat-announced-prefixes`. HTML page: https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/ripestat-announced-prefixes ## Facts - Tool: `ripestat-announced-prefixes` - Server: Meta Data Mcp (`pypi:meta-data-mcp`) — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp.md - Install: `npx -y pypi:meta-data-mcp` - Homepage: https://github.com/derekslinz/meta-data-mcp - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "ripestat-announced-prefixes", "arguments": {} } } ``` ## Why ripestat-announced-prefixes is rated Low This tool queries and retrieves historical or current routing announcement data from RIPE's public database. It is a read-only operation that returns information about IP prefixes without any side effects, modifications to data, or triggering external operations. The low severity reflects that this queries publicly available network data with no ability to alter, delete, or execute actions. From the tool's own definition: "Tool 'ripestat-announced-prefixes' performs a 'List' operation on IP prefix data announced by an ASN. The description indicates pure data retrieval with no modification, deletion, execution, or financial transaction capability." ## Use case AI agents call ripestat-announced-prefixes to retrieve information from Meta Data Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Meta Data Mcp: ```json { "version": "1", "default": "deny", "tools": { "ripestat-announced-prefixes": {} } } ``` ## Other tools on Meta Data Mcp (395) - `hackernews-new-stories` — Execute — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/hackernews-new-stories.md - `opendata_plugins_create` — Execute — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/opendata-plugins-create.md - `ovapi-stop-departures` — Execute — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/ovapi-stop-departures.md - `overpass-query` — Execute — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/overpass-query.md - `ssllabs-analyze` — Execute — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/ssllabs-analyze.md - `wikidata-sparql` — Execute — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/wikidata-sparql.md - `arxiv-get-paper` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/arxiv-get-paper.md - `arxiv-query` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/arxiv-query.md - `arxiv-search-by-author` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/arxiv-search-by-author.md - `arxiv-search-by-category` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/arxiv-search-by-category.md - `arxiv-search-by-title` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/arxiv-search-by-title.md - `au-data-gov-get-dataset` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/au-data-gov-get-dataset.md - `au-data-gov-get-organization` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/au-data-gov-get-organization.md - `au-data-gov-list-groups` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/au-data-gov-list-groups.md - `au-data-gov-list-organizations` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/au-data-gov-list-organizations.md - `au-data-gov-list-tags` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/au-data-gov-list-tags.md - `au-data-gov-search-datasets` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/au-data-gov-search-datasets.md - `awc-metar` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/awc-metar.md - `awc-station` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/awc-station.md - `awc-taf` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/awc-taf.md - `ca-open-gov-get-dataset` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/ca-open-gov-get-dataset.md - `ca-open-gov-get-organization` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/ca-open-gov-get-organization.md - `ca-open-gov-list-groups` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/ca-open-gov-list-groups.md - `ca-open-gov-list-licenses` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/ca-open-gov-list-licenses.md - `ca-open-gov-list-organizations` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/ca-open-gov-list-organizations.md - `ca-open-gov-list-tags` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/ca-open-gov-list-tags.md - `ca-open-gov-search-datasets` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/ca-open-gov-search-datasets.md - `cbs-get-metadata` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/cbs-get-metadata.md - `cbs-get-typed-dataset` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/cbs-get-typed-dataset.md - `cbs-list-tables` — Read — https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/cbs-list-tables.md - …and 365 more: https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp.md ## For agents This record is a snapshot.
