# courtlistener-get-opinion Fetch a single CourtListener opinion (with full text) by numeric id. Agent View of the PolicyLayer registry record for `courtlistener-get-opinion`. HTML page: https://policylayer.com/tools/io-github-derekslinz-meta-data-mcp/courtlistener-get-opinion ## Facts - Tool: `courtlistener-get-opinion` - 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": "courtlistener-get-opinion", "arguments": {} } } ``` ## Why courtlistener-get-opinion is rated Low This tool queries a public legal database (CourtListener) to retrieve existing opinion documents. It performs a simple retrieval operation without creating, modifying, deleting, or executing any operations. The data returned is already public information. The blast radius of misuse is minimal—an agent could retrieve many opinions but cannot modify or delete them, and the information is already publicly accessible. From the tool's own definition: "Tool fetches a single CourtListener opinion by numeric id. The verb 'fetch' and the operation of retrieving 'full text' indicate data retrieval with no modifications or side effects." ## Use case AI agents call courtlistener-get-opinion 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": { "courtlistener-get-opinion": {} } } ``` ## 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.
