Implementation Reference

• src/evm/modules/network/tools.ts:41-50 (handler)

  Handler function for get_supported_networks tool: retrieves supported networks using getSupportedNetworks() and returns them wrapped in mcpToolRes.success.

  async () => {
    try {
      const networks = getSupportedNetworks()
      return mcpToolRes.success({
        supportedNetworks: networks
      })
    } catch (error) {
      return mcpToolRes.error(error, "fetching supported networks")
    }
  }

• src/evm/modules/network/tools.ts:37-51 (registration)

  Registers the get_supported_networks tool on the MCP server with description, empty input schema {}, and inline handler function.

  server.tool(
    "get_supported_networks",
    "Get list of supported networks",
    {},
    async () => {
      try {
        const networks = getSupportedNetworks()
        return mcpToolRes.success({
          supportedNetworks: networks
        })
      } catch (error) {
        return mcpToolRes.error(error, "fetching supported networks")
      }
    }
  )

• src/evm/chains.ts:179-183 (helper)

  Core implementation: extracts keys from networkNameMap, filters out short aliases (length > 2), sorts, and returns the list of supported network names.

  export function getSupportedNetworks(): string[] {
    return Object.keys(networkNameMap)
      .filter((name) => name.length > 2) // Filter out short aliases
      .sort()
  }
