# get_etf_overview GET /etfs/overview Agent View of the PolicyLayer registry record for `get_etf_overview`. HTML page: https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-etf-overview ## Facts - Tool: `get_etf_overview` - Server: REI Crypto MCP Server (`0xreisearch/crypto-mcp-beta`) — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta.md - Homepage: https://github.com/0xReisearch/crypto-mcp-beta - Risk category: Read (Low risk) - Registry record: grade B, 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": "get_etf_overview", "arguments": {} } } ``` ## Why get_etf_overview is rated Low This is a straightforward data retrieval operation. The GET HTTP method is inherently read-only and returns ETF overview information. There are no side effects, no code execution, no financial transactions, and no destructive operations. The tool fits the Read category as it 'retrieves or queries data; no side effects'. From the tool's own definition: "Tool name 'get_etf_overview' and description 'GET /etfs/overview' indicate a read-only HTTP GET request that retrieves ETF overview data without modifying, deleting, or executing operations." ## Use case AI agents call get_etf_overview to retrieve information from REI Crypto MCP Server 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 REI Crypto MCP Server: ```json { "version": "1", "default": "deny", "tools": { "get_etf_overview": {} } } ``` ## Other tools on REI Crypto MCP Server (116) - `date_to_timestamp` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/date-to-timestamp.md - `get_active_users` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-active-users.md - `get_api_important_entities` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-api-important-entities.md - `get_balances_address` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-balances-address.md - `get_balances_entity` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-balances-entity.md - `get_batch_historical_prices` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-batch-historical-prices.md - `get_bridge_day_stats` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-bridge-day-stats.md - `get_bridge_details` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-bridge-details.md - `get_bridge_transactions` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-bridge-transactions.md - `get_bridge_volume` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-bridge-volume.md - `get_bridges` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-bridges.md - `get_categories` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-categories.md - `get_chain_assets` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-chain-assets.md - `get_chains` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-chains.md - `get_closest_block` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-closest-block.md - `get_coin_by_contract` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-coin-by-contract.md - `get_coin_by_id` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-coin-by-id.md - `get_coin_markets` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-coin-markets.md - `get_coin_ohlc_range` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-coin-ohlc-range.md - `get_counterparties_address` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-counterparties-address.md - `get_counterparties_entity` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-counterparties-entity.md - `get_current_prices` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-current-prices.md - `get_current_time` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-current-time.md - `get_derivatives_overview` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-derivatives-overview.md - `get_derivatives_summary` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-derivatives-summary.md - `get_dex_overview` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-dex-overview.md - `get_dex_overview_by_chain` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-dex-overview-by-chain.md - `get_dex_summary` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-dex-summary.md - `get_emission_data` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-emission-data.md - `get_emissions` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-emissions.md - …and 86 more: https://policylayer.com/tools/0xreisearch-crypto-mcp-beta.md ## For agents This record is a snapshot.
