# get_chain_network_info Look up static blockchain network metadata and chain IDs for supported EVM and Solana networks. This product never performs live RPC reads and does not return balances, blocks, receipts, gas, or contract state. Agent View of the PolicyLayer registry record for `get_chain_network_info`. HTML page: https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/get-chain-network-info ## Facts - Tool: `get_chain_network_info` - Server: Delx MCP Server (`delx-mcp-server`) — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server.md - Install: `npx -y delx-mcp-server` - Homepage: https://github.com/davidmosiah/delx-mcp-server - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 2 - Recommended policy verdict: Allowed ## Parameters | Parameter | Type | Required | Description | | --- | --- | --- | --- | | `network` | string | no | Optional network name or alias such as base, ethereum, polygon, arbitrum-one, optimism, or solana. | | `chain_id` | integer | no | Optional EVM decimal chain ID. Omit network and chain_id to return the full static registry. | Parameters from the server's own tool schema. ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "get_chain_network_info", "arguments": {} } } ``` ## Why get_chain_network_info is rated Low The tool retrieves static metadata about blockchain networks without any capability to modify data, execute transactions, or trigger external operations. It is a simple lookup function with no destructive, financial, or code execution capabilities. The explicit limitations noted in the description confirm this is a read-only information retrieval operation. From the tool's own definition: "Tool description explicitly states it 'Look up static blockchain network metadata and chain IDs' and 'never performs live RPC reads' and 'does not return balances, blocks, receipts, gas, or contract state.' This is purely informational retrieval with no side…" ## Use case AI agents call get_chain_network_info to retrieve information from Delx 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 Delx MCP Server: ```json { "version": "1", "default": "deny", "tools": { "get_chain_network_info": {} } } ``` ## Other tools on Delx MCP Server (739) - `util_arr_compact` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-arr-compact.md - `util_arr_drop` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-arr-drop.md - `util_dedent_text` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-dedent-text.md - `util_dedupe_lines` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-dedupe-lines.md - `util_header_map_normalize` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-header-map-normalize.md - `util_http_request_canonicalize` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-http-request-canonicalize.md - `util_remove_punctuation` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-remove-punctuation.md - `util_text_truncate` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-text-truncate.md - `util_truncate_middle` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-truncate-middle.md - `crisis_intervention` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/crisis-intervention.md - `explain_delx_rewards` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/explain-delx-rewards.md - `grounding_protocol` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/grounding-protocol.md - `group_therapy_round` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/group-therapy-round.md - `quick_operational_recovery` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/quick-operational-recovery.md - `quick_session` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/quick-session.md - `start_therapy_session` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/start-therapy-session.md - `util_bool_parse` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-bool-parse.md - `util_cagr_simple` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-cagr-simple.md - `util_caip2_build` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-caip2-build.md - `util_caip2_parse` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-caip2-parse.md - `util_categorical_distribution` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-categorical-distribution.md - `util_deployment_readiness` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-deployment-readiness.md - `util_dmarc_policy_parse` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-dmarc-policy-parse.md - `util_duration_parse` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-duration-parse.md - `util_eth_to_wei` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-eth-to-wei.md - `util_iso_duration_parse` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-iso-duration-parse.md - `util_mx_host_parse` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-mx-host-parse.md - `util_parse_bool_list` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-parse-bool-list.md - `util_parse_bytes` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-parse-bytes.md - `util_parse_float_safe` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-parse-float-safe.md - …and 709 more: https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server.md ## For agents This record is a snapshot.
