# get_chain_assets GET /api/chainAssets Agent View of the PolicyLayer registry record for `get_chain_assets`. HTML page: https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-chain-assets ## Facts - Tool: `get_chain_assets` - 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_chain_assets", "arguments": {} } } ``` ## Why get_chain_assets is rated Low This is a straightforward data retrieval tool that queries blockchain asset information. GET requests are inherently read-only operations that do not modify, execute, delete, or create any data. The blast radius of misuse is minimal—an agent could only retrieve information it shouldn't have access to, not cause irreversible harm or execute arbitrary operations. From the tool's own definition: "Tool name 'get_chain_assets' and description 'GET /api/chainAssets' indicate a read-only API endpoint that retrieves chain asset data." ## Use case AI agents call get_chain_assets 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_chain_assets": {} } } ``` ## 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_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 - `get_entities` — Read — https://policylayer.com/tools/0xreisearch-crypto-mcp-beta/get-entities.md - …and 86 more: https://policylayer.com/tools/0xreisearch-crypto-mcp-beta.md ## For agents This record is a snapshot.
