# openaq-list-locations List OpenAQ air-quality monitoring locations. Filter by coordinates Agent View of the PolicyLayer registry record for `openaq-list-locations`. HTML page: https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/openaq-list-locations ## Facts - Tool: `openaq-list-locations` - 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": "openaq-list-locations", "arguments": {} } } ``` ## Why openaq-list-locations is rated Low This tool queries public air-quality data from OpenAQ, an open data API. It retrieves information about monitoring station locations filtered by geographic coordinates. There are no data modifications, deletions, code execution, or financial transactions. The blast radius of misuse is minimal—an agent could only return unwanted or excessive lists of location data, which causes no harm. From the tool's own definition: "Tool name 'openaq-list-locations' and description 'List OpenAQ air-quality monitoring locations' indicate retrieval of data. The 'Filter by coordinates' clause confirms this is a query operation with no side effects." ## Use case AI agents call openaq-list-locations 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": { "openaq-list-locations": {} } } ``` ## 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.
